Warning:I am not responisible for any damage to your phone and rooting usually nullifies the warranty. so please procede with your own risk
I tried to root my karbonn A2 for 2 weeks and finally i got it. so im gonna share the steps involved in rooting and also provoide the tools for it.
NOTE: I do not take credit for any tool since all the tools were already available online, so credit goes to whoever programmed them. only thing i did was to alter the method slightly to get my phone rooted.
Lets begin. Before we start rooting our phone, most important thing is the drivers. so u need two types of drivers one is ADB (android debugging bridge) drivers and the other is preloader drivers. i have attached both of these drivers in the attachments u can download it.
Step1[only for beginners]: Go to setting>applications>development>enable USB debugging in the phone, then connect your phone to ur pc (remove all previous drivers if u have installed) then go to device manager>devices, right click on the usb device and click update driver and browse to folder containing the SPdrvers (u need to extract the folder from the attachment first).If driver is successfully installed then u should see "android phone" in ur device manager. to confirm it just run adb devices from the command line by chagning the directory to where adb.exe is, u should see the list of devices attached to ur pc. (usually adb.exe will be in android sdk tools folder or if u dont have one then check in ADB folder from superoneclick in the attachment).
Step2: ok, now that u have installed adb drivers, u need to install preloader driver (also known as downloading mode in some devices). to do this, disconnect ur phone from the pc, then switch off the phone, remove the battery and then connect ur phone to pc again (without the battery). then u should see windows trying to install drivers and fails. then go to device manager again and browse to folder containing USB VCOM drivers (see attachment). after it successfully installs procede to step 3.
Step3:: download, extract the files MTKROM and SPflash tool to ur pc. then put the battery inside ur phone then switch it on, connect it to pc (enable debugging all the time). then open command line then go to adb folder then type :adb devices- u should see the list of device attached (u will get some long numbers so dont worry). then type "adb shell" (without the quotes). u will get a $ sign, then type "cat proc/mtd > /sdcard/firmware.info" if its successful then a file named firmware.info will be created in ur sdcard root. then copy that file to ur pc.
Step 4: Now open that firmware.info in MTKROM.exe u should see a list tables and address like in the image below. then click save scatter and rename the filename to MT6575 instead of MT6573 (and leave everthing else as it is). so a file named "MT6575_Android_scatter.txt" will be created.
Step 5: Now open Spflash tool and load the scatter file in that. u should see something like this in the image below.
STEPS TO BACKUP ORIGINAL BOOT AND RECOVERY
Step 6: Before we actually begin to root its important to make a backup of current images. so to do that, go to READ BACK tab in sp flash tool. click on Add>double click on the page file and save as "Boot.img" somewhere safe. then click on "Read Page only", this is very important. then look at the address side by side from MTKROM and enter into sptool. the start address is the address in which the boot.img begins and length is the length of boot.img. so final address will be startaddress+length =start address of next image (recovery.img). In MTKROM the start address is given as "PART ADDRESS". after entering those carefully click ok. if u want to be sure then use programmer calculator and add the address.
Note :the address will be in hexadecimal format not decimal.
Step7: In order to read the firmware from the phone, disconnect the phone from your pc, remove the battery, dont connect it yet. now click on "Read back" button in the sptool (its after Add,remove button). now the software starts searching for the device. now connect the device to the pc (without battery ofcourse). now if have installed USB VCOM drivers correctly then the sp tool should detect ur device and start reading from it. u will see Red colour in the
task bar when it detects then blue colour while the tool is reading the phone. wait untill the reading is complete. A green circle will pop up after it successfully reads from the device. (refer the images below)
Step 8: repeat step seven as described above for recovery.img (save the file as recovery.img) then select "read page only" option, enter start address as 0x0980000 and length as 0x0500000. (please enter the address carefully cross check with MTKROM image addresses.)
Note: You have to disconnect the device first then click read back button after entering the addresses then connect the device, otherwise the sptool wont detect your device!.
Actual Rooting Procedure
Step 9: Now that you have backed up both boot and recovery images its time to start the actual rooting. download the boot.img file from the attachment and save to your pc (dont replace it with your backup image that you saved earlier). go to download tab in the sp tool and tick only boot.img and uncheck all others (if any of them has been checked already) and click on Bootimg and browse for the folder where u downloaded boot.img from the attachment and NOT THE BACKUP! after that disconnect your device, then click download button above( after format->upgrade button) or f9 from keyboard. the tool will start searching the usb com ports. now connect your device and wait till it downloads fully. Note: In downloading your will get RED colour first, then YELLOW colour while flashing, and finally a GREEN circle after flashing is complete).
Step 10: The most important and complicates steps are over. now all you have to do is put your battery to your phone and switch it on. now after it sucessfully boots up, open superonclick.exe (you will get this software online and its very popular tool for rooting) and connect the device to your pc (enable debugging of course), then click Root button in superoneclick and Voila! your phone is rooted. enjoy and dont forget to press thanks button if ive helped
Note: u will need .NET framework 3.5 to run superoneclick.
Method To Unroot
For unrooting your mobile all you have to do is flash the original, backup boot image back to your phone. just open sptool and load the scatter file, then click on bootimg then browse to wherever u have stored backup boot.img then click download button then connect your device without the battery and thats it. you will get back original firmware without the root!.
Clockwork mod recovery for A2
There is no official cwm recovery for A2, but i ported cwm for other MT65xx devices to A2. so here are the steps to flash.
step 1: download recovery.img from the attachment.
step 2: open sp flash tool and load scatter.txt (for detailed description refer rooting steps). then tick recoveryimg and browse and set the path of the recovery.img you just downloaded from attachment.
step3: click on download button at the top or press f9. then take out the battery from the phone and connect it to the pc. the tool will detect your phone and start flashing cwm recovery.wait untill the green circle pops up.
step 4: now put in the battery and press power button+volume up and hold it for few seconds and voila!! cwm recovery boots up. And to revert back to original recovery just flash the recovery.img that you backed up during rooting process using the above steps.
Note: Do Not factory reset your phone without backing up the IMEI number. After rooting your device please backup your phones IMEI number which is stored in data/nvram/md/NVRAM/NVD_IMEI/MP0B_001 to a safe place. or there is an application called mobileuncletools (a chinese app) which helps to backup your IMEI to sdcard and restore it back. if u loose your IMEI and reset your phone then you cannot call or recieve sms etc
No service and invalid IMEI solution
explanation:
In case u did factory reset of the phone, then all your data will be wiped including the imei number. it will be reverted to factory imei number, hence you cannot connect to any mobile networks in india or anywhere else because most network operators wont allow to use the network with dupicate or invalid imei numbers. every device has a specific imei number. in this device your original imei numbers (15 digits) will be on the back of your battery.
Restoring is tough very simple procedure, creating the required files is a major headache. At first i thought it was impossible to restore the imei back (trust me i tried all the available solutions that u get in the internet, infact there are 5 different types of solutions, none of which worked for this device). luckily one day i found a chinese software which actually did create a imei file that is compatible with this device (phew !, yeah i know) and so i did successully restored my imei back and i can once again connect to mobile network and make calls..:victory: so here it goes.
How to restore IMEI number? (MUST BE A ROOTED PHONE)
1) if u have made the backup of MP0B_001 file in /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001 , then install root explorer and simply replace your current file with the backed up MP0B_001 and set the permissions to rw-rw---- and restart.
2) if u havent backed it up (too bad), then download the chinese software sn_gen.zip from the attachments and enter both imei numbers that is found in the back of your battery (enter the numbers correctly and cross check it again, its 15 digit number). then the software generates a new MP0B_001 file, copy and paste in the above mentioned directory and set the permissions to rw-rw---- and restart.:fingers-crossed:
dont forget to press thanks button if ive helped you :good:

its not possible to put ICS in A2 (since its officially not supported to our device), although cyanogenmod 9 can be installed but its very difficult to build it since most of the drivers are properitery and they wont release the sources. so its almost impossible to run cm9 and even if someone did build cm9 it wont run smoothly because of very low amount ram in our device (<256MB and ICS needs more than that to work smoothly). however im working to build cm7 (based on gingerbread) for our device and even that is really difficult since there is no device tree in github for this device. so i need build cm7 from scratch and that is not an easy job. so if any developers are working on building cm7 for A2 please pm me so that we can work together..

if we create any partion sd memory for our internal memory can it run cm10 b'cuz galaxy ace can run cm10 it has just 256MB ram and some wat 800MHZ speed only but our device has 256MD ram with 1GHZ processor speed so i think it can also run cm10 if we create a partition memory from ous sd card thats wat i think so........
waiting for reply from ur side thanks in advance.......
urgent help
i tried to reset my karbonn a2 and done it after reboot it shows no service and also no network wat to do pls tell me thanx in advance..........

lol i was a galaxy ace user untill last dec. (its touch digitizer got broke, so i temporarily bought karbonn). anyway i do know ace can run cm10 and pretty much any device can, even ours can run it. i did not say our device doesnt run at all. i said it wont run smoothly and developing cm other than stock os version is very very difficult since our device is a local device and threre is no lot of support for it. so if anything goes wrong we may permanently brick our devices and may not find solution at all.
on the other hand, since i was a former ace user, i know that even though ace can run cm9 and cm10 there were a lot of problem in getting camera, video recording, and other applications because of unavialablity of their sources. so furthermore most of extra features that arent available in gingerbread cannot be used ex: face recognition, google now,otg usb etc( they are built for high end devices). u wont notice the difference in optimizations and performance of jelly bean in low end devices because they need sufficient hardware to utilize the os to full extent. so only thing u get out of installing cm is user interface (which u can change using of launchers, oh yes there are big bunches of launchers out there) and some features of cm (deodexd rom,custom kernel with overclocking features and some tweaks.)
coming back to our device, ive been trying to build cm7 for our device and its really difficult without a device tree and some good prior experience in building cm for atleast 2 devices. so my advice is that first we will build a fully working cm7 for our device and later if possible we will port cm10.

what do u mean by reset? did u do factory reset from recovery or did u clear flash from by holding power+down? (oh btw recovery is power+up in our device).
either way ur imei number has been erased and it will be reset to factory number . i spent 1 week day and night searching for a solution and that is exactly why i told u to backup your MB0P_001 file.
in order to repair it u need to root ur phone. follow above steps and paste ur imei number (dial *#06#).
Nothing in SuperOneClick
I am successful in doing everything, but when I open SuperOneClick, it does not show any device, and clicking "Root" greys off the button for a few seconds, and everything is back to normal again. Nothing happens to the phone.
What is wrong?

ru sure u replaced boot.img which was attached in attachments to your phone? if it was successful then u have unlocked the bootloader. the problem here seems to be like superonclick isnt detecting ur phone when connected to pc. In case if the usb debugging is turned off enable it and check if ur device is listed in adb devices command as explained above. if it does and still rooting doesnt work, then maybe you are using wrong version of superoneclick. because some of the loopholes which is used to root your phone (by gaining temporary access to shell) is not available in older versions. the version must be compatible with gingerbread. try downloading superonclick 2.3.3 version.
also, after u root with superonclick, restart it and please check if u have superuser app in ur phone(it will be automatically installed by superoneclick, dont install it manually since the app should be in /system/app and su command should be in /system/bin directory, which u cannot do by installing it manually). if its installed then u have root access, if u still want to confirm just download root checker app from google play and run it.
CM10 means Jelly Bean Which has minimum Requirement of 512MB ram... device cant even Support Cm9(ics)...And generally cynogenmods are not developed for local Indian Brands.....Instead Try this making your phone look like XPERIA:

Thank you..... finally found out where I went wrong... now my phone is rooted..... A hundred thanks....:victory:
Hello,
In this thread I will teach you every method I had to use to root any Spreadtrum devices, Starting with the riskless ones to the reckless ones.
I have to warn you that the last root method (using ResearchDownload to load a modified system.img) may be dangerous ! (because of possible partition table changes)
The others methods are pretty safe, don't be afraid by them if you do exactly what I wrote.
Theses processors are also named SP6820 and SP8810, it's exactly the same processor, it's just some misnaming from Chinese sellers.
Theses methods do work on the newest Spreadtrum CPUs, like the SC7710 (the 3G WCDMA model), and the more powerful SC8825/SC6825 (dual core).
Why buying a Spreadtrum based phone ?
They are really cheap, and they work amazingly well ! They can play some games and emulators very well, that's unexpected for such low end devices (50$ or less)
They usually only have 256MB of RAM but despite that, they still runs well ! (I tested a lot of games and some 3D games are working flawlessly, pretty amazing) - I discovered that they are using zram (or other swap methods) to provide more RAM by compressing it when needed. That's pretty neat and really helps with such a small amount of RAM !
They are very good as a portable multimedia device, to read mails, browsing the web, play some games, mp3, videos.
As a 2G phone they are competent, but the 2G modem is not as good as the one in MTK processors. (It takes longer to load something in the same conditions)
Boot very fast, and have decent battery life. (3-4 hours of video out of a 1200 mAh battery - 5-6 hours out of a 1800 mAh)
Why you should not ?
Not true anymore, but they were extremely difficult to root in some cases.
They don't seem to be well tested ... You can have a microphone so quiet nobody will be able to ear you. But it's easy to fix as you can see here: http://forum.xda-developers.com/showthread.php?p=38731407
They don't have any form of usable 3G support. (except the SC7710 who have WCDMA 850/2100 compatibility)
They usually have only 256MB of RAM again. So that can be a problem when you are, for example, using Opera Mobile Classic with more than 3 tabs. And make the transition between apps longer.
SC6820 and SC8810 model are all using Android 2.x, even if some are marketed as Android 4.0 phone (very big and blatant lie !)
They usually use android 2.3, but some are only Android 2.2 phones ! (The fake Android 4.0.3 for instance is usually only android 2.2)
SC6825 and SC8825 seems to only have a (real this time) Android 4.0.3 firmware. 4.1 are better is often advertised, but it's again ... lies ... Android 4.0 is not really suitable for phones with only 256 MB of RAM, so SC6825/8825 phones are pretty rough on the edges. Using more than one tab on the default web browser is asking for troubles for example.
They all use the MocorDroid Firmware. It's some kind of fork of Android that use NON-Standards and sometime buggy Launchers and they often use alternative keyboards like Go Keyboard which is kind of a bad choice considering the RAM and ROM constraints on theses devices ...
The only difference between the SC6820 and the SC8810 is the support for the Chinese form of 3G.
If you don't live in china, that means this two processors are essentially the same. (Don't trust sellers, the 8810 is NOT WCDMA "3G" compatible)
Some phones with the fake Android 4.0.3 based on 2.3.5 will brick themselves nearly 2 months after you first used it. It's a really weird behavior of this early Spreadtrum firmware. So if you have this firmware, just do whatever it takes to root it, make a backup and install CWM as soon as possible to be able to recover from this possible breakage. It's only a problem with a fraction of Spreadtrum phones, but you will be very happy if you have installed CWM before encountering it ^^ (applicable only if you bought one in 2012)
A lot of fakery in the Spreadtrum scene. For example fake MTK6515/MTK6572 phones that are in fact just SC6820/SC6825 phones with a firmware modified to lie its processor ID to populars android benchmarking tools like Antutu Benchmark.
If you are searching for a 512MB RAM phone, you'd better go for an MTK(6575/6572 or better) Phone. As you will never find a real 512MB Spreadtrum phone in the jungle of lies you are looking at ...
On all model with 2.3.5 based firmware (SC6820 and SC8810 essentially), you can have a lot of problems with the SIM card detection on some sim cards. For example I can't call somebody with mine, but I can answer a call or send/receive SMS ... Very weird bug ...
This bug seems to be related on the type a sim card you have. With some their is no problem at all.
I can confirm that it's working flawlessly on SC6825 and 8825 based phones with the real 4.0.3 based firmware.
Why rooting it ?
Because a lot of them come with a lot of sh*tty softwares, including the bad launcher and keyboard.
Because they can come with a "Virus" that can send SMS messages to china (so you have to pay for unwanted international SMS cost)
I myself have this Virus on one of my phones, as of now, I haven't noticed anything unusual. Just the useless, unkillable com.android.caivs.app process eating 15 MB of RAM doing nothing. (It is a significant waste of ram on such devices)
(As of now I only seen this malware on Feiteng devices - You can share your experience with this thing down bellow)
More about CAIVS here: http://web.archive.org/web/20110812021151/http://www.cseed.cn/chinese/news/portfolio2.htm
That virus was on most of the earliest Spreadtrum phones but don't seem to be a worry nowadays. But I haven't tried any new Feiteng devices. They were so poor in quality that I will never buy feiteng again so find it by yourselves if you feel adventurous xD
How-to do that ?!
If you are lucky you will be able to root your phone by traditional means.
If you are not, you can root them by manually adding the root utilities to the ROM.
I will describe every methods that you should try in order of difficulty and risks.
Before doing any of that, go to the android setting -> applications -> Development -> Check USB Debugging.
Universal Root utilities
Theses methods are safe, and the second one is, as of now, working on every Spreadtrum phones flawlessly !
1.1 - Z4Root
Just try z4root !
http://forum.xda-developers.com/showthread.php?t=833953
z4root is a little tool to root Android 2.2 and sometime work on 2.3
It's known to work on devices with the fake Android 4.0.3 based on 2.2 and MocorDroid 2.2.2
It may work on more of them, just try, there is no risks at all.
Make sure you have at least 50 MB of available space on the /data partition before trying this. (not the SDCard, the Applications Space)
Try a temporary root to see if it works, then you can do the permanent root.
You will maybe have to try it 2 or 3 times before it works.
Even if it doesn't work, reboot the phone after this. Because it can eat your battery while running in the backgroung if it fails.
1.2 - vRoot
vRoot is a chinese tool to root many devices !
It's proved to work very well with Spreadtrum (and MTK) devices. I used it successfully on a lot of Spreadtrum devices, even the most recent ones (SC8825).
You only need a Windows Computer (I personally use it on Windows 7 32bits).
Then download it from here: http://www.mgyun.com/en/getvroot
Install it and then open it.
As of now you only need to plug your USB cable to your computer, and then click on the Root button. (you don't need to do anything else, don't touch your phone)
Once it's done and the phone rebooted you will be rooted !
The root app is some kind of custom chinese one, but it's working properly.
Don't try to replace it with SuperSU as SuperSU don't seem to work properly on Spreadtrum devices.
If you want to understand what the root app is saying, try to set the language on your device to English.
2 - Custom Firmware Flash
Please never use any custom firmware available in .pac file format ! Or at least, don't use them before doing a full backup of your current firmware !
Feiteng A7100 (only if you have the mt6515_c910_ht_en_4.0_v01 rom/firmware on it !!! If not, don't touch it, you will end up with a brick ! Or screen reversed, or other strange bugs): http://forum.xda-developers.com/showthread.php?t=2149396
If you have a Feiteng A7100 I really recommend NOT TO USE this rom ! Why ? Because it only works on a fraction of A7100, newer releases of the same phone don't use the same firmware. With this tutorial here, you can root your A7100 easily and way safer. Please go to "4-" on this tutorial to know how to root your A7100.
If you append to find some others Custom roms for spreadtrum devices, or are making one, please send me a PM, I will link them here.
3 - Fastboot to the rescue !
If every fast, simple and secure methods are not working, then this will be difficult my friend !
3.1 - Find Fasboot
First, let check if we have fastboot in your phone !
Fastboot is a little tool inside the bootloader. It's here to help you flash the firmware.
Not every Spreatrum phones have it, so let's check if you are lucky !
You can access it by powering on the phone up while holding a key.
First power off your phone.
Then hold some button like volume+
while pressing this button, press and hold down the power button.
Keep holding the two buttons until the screen light up.
You should now have something on your screen. Maybe a system diagnostic tool (a menu with a set of system tests, that's totally useless) or maybe the recovery mode (a screen with a warning sign, and now your phone is stuck here until you pull out the battery) or, and that means victory, a screen that says "Fastboot".
If you are not on fastboot, but are on the Recovery or the System Test, turn the phone off again and try another button press at boot time exactly like I said before.
This time, try the Home button if you have one, or the Volume-.
You should also try buttons combinations. Like volume up and down at the same time. Home + vol Up, etc and maybe the 3 at the same time ...
(if you just boot as if nothing was pressed, you maybe have to unplug the battery, wait for a while and put it back before powering the phone on. Theses things are also not working when the usb/charging cable is plugged in - if some keys combinations are not doing anything, it's perfectly fine, it means they don't trigger any hidden boot mode)
If nothing bring fastboot up, you have to use the Spreadtrum Debug tool "ResearchDownload" ...
So Skip to "4-" ! ^^
3.2 - Install the drivers
If you append to find Fastboot, we will have to install the PC part of it !
Like every android phone, you have to install adb and his drivers to access the Android Debug Bridge.
You can find them and learn how they work here: http://dottech.org/21534/how-to-ins...ows-computer-for-use-with-your-android-phone/
On Ubuntu or Debian Linux you just have to install them that way:
Code:
sudo apt-get install android-tools-adb android-tools-fastboot
You also have to install the phone drivers if you are using Windows:
ADB Drivers: http://www.mediafire.com/download.php?c5nf3rlhxmxhu4x
Debug Drivers: http://www.mediafire.com/download.php?2tyg0k2xp3ejgyg
Mirror: http://www.mediafire.com/?o9km8vl287ev24j
Then you will have to tell adb what phone to use. By that I mean adding the PCI ID to a text file to tell adb that this peripheral is compatible.
The Spreadtrum PCI ID is 0x1782
add this line to "Your user directory/.android/adb_usb.ini"
Code:

3.3 - Using fastboot to load CWM (Clockwork Mod)
CWM work on some of theses Spreadtrum devices, most of the time, the screen is reversed, but it works !
On some phone, you will be presented with a blank screen, but CWM will work ... That will just be very difficult to navigate ... (don't bother and use another method if you append to be in this boat)
Here are the recovery images available for Spreadtrum device to my knowledge:
* http://www.mediafire.com/download.php?u6uyignmdcpillt - extracted from a random SC6820 that I don't remember
* http://www.mediafire.com/download.php?bosnfcq9n65mtc5 - i9270+
* http://www.mediafire.com/download.php?xem49dy5dh99ml0 - 5830, S5830, Q5830, Q206 and GT-N9300 (maybe more)
* http://www.mediafire.com/download.php?adfwq6b5268qb58 - S9300 (SC6820A S3 Clone)
* http://www.mediafire.com/download.php?y2f7aaan4b00l1m - Feiteng GT-A7100 and probably more Feiteng devices.
* http://www.mediafire.com/download.php?lg7m6v49efzpnjk - 6500-TV or S560
* http://www.mediafire.com/download.php?6xn977jjsuusjan - N9300 (I9300 Clone)
* http://www.mediafire.com/download.php?d68wc334qn47tdd - S930 or N8820
If your device is not listed or the one for your device doesn't work, try them all, even if your phone is SC6820 and the recovery was made for SC8810, if none are working, we will have to flash the entire system partition, which is a lot more difficult and dangerous ...
Flashing CWM to the phone:
Linux Only: Initialize ADB:
Code:
sudo adb kill-server
sudo adb start-server
Boot your phone in fastboot mode.
Be sure your device shows up:
Code:
fastboot devices
if your device show up, it's time to flash
Code:
fastboot flash recovery recovery.img
It's flashed ! Let's reboot now.
Code:
fastboot reboot
Start on CWM, if it works, you can start to root the phone !
Download this patch: http://www.mediafire.com/download.php?131nsw87afzwb5v
Put it on the root of your SD Card.
Now you will have to boot on CWM, he is on the same key combination than the old useless recovery was. (Most of the time Volume- and Power)
You can also try this command with adb:
Code:
adb reboot recovery
Now it's the perfect time to do a full backup of your firmware with CWM, so please do so, that can come in handy. (please go to the end of this tutorial after rooting your phone to know how to make a FULL backup. CWM will only make a partial one.)
choose apply update.zip
Choose the file you have put on your sd card before
Apply it then reboot.
This update.zip have pushed everything needed to root your phone in the right place, you should be rooted now !
If you have an error like:"Can't mount /sdcard" you may have to try with another SD Card and be sure your SD Card if formated as Fat32.
3.4 - Using Fastboot to load a modified system partition image
Please follow the instructions down bellow on how to "5 - Create a rooted system partition image"
When you have done your Rooted system partition image, flash it like that:
Code:
sudo fastboot devices
#if your device show up, it's time to flash
Code:
sudo fastboot flash system system.img
#It's flashed ... Now let's reboot with all the apprehension of the world
Code:
sudo fastboot reboot
If it boots (should boot), you will be up and rooting !
4 - Spreadtrum ResearchDownload tool to the rescue !
First, if you have fastboot, use fastboot ! It's simple, more reliable, faster. It's bottomline better !
If you don't have fastboot or can't figure out how to bring him up on your phone despite trying for about an hour. This tool will most likely work.
First, you should use Windows XP 32bits. Even real XP or in virtualbox.
It might work on windows 7 32 bits and 64 bits but you will have to tweak the system to allow installation of non signed devices drivers ...
ResearchDownload work as this:
First you start the Channelserver - This thing is here to make a bridge between the tools and the driver.
Then you start ResearchDownload.
Now you can make a full firmware flash (you should not !! It's a terrible idea !) or flash a single partition. But to do that, unfortunately, you should have a compatible set of fdl files.
Finding them on google is impossible, you have to extract them from your full firmware .pac file.
If you can't find your firmware on the Internet, you will have to try every single one you can find from others firmwares. I gathered all the fdl files I could find in a single package, so it won't be that difficult.
It's highly probable that you will find one that will work with your phone. This thing have to boot the phone and flash the Nand Flash chip. I'm pretty sure there is not a lot of different ways to do this on a single processor.
I really don't know the risks of using a wrong fdl set. But we haven't seen any risks at all yet. Some will work on your phone, others will just do nothing. You will just have to try every single one until one work.
I named the folders with the names of the phones I know working with theses. So it will be easier to find the good one. (A7100, 6500-TV, 5830, Q206 and S930 users will feel very lucky ^^)
4.1 - Learn how ResearchDownload Work
First you have to install the drivers, you can find them here:
ADB Drivers: http://www.mediafire.com/download.php?c5nf3rlhxmxhu4x
Debug Drivers: http://www.mediafire.com/download.php?2tyg0k2xp3ejgyg
Then you have to plug your phone to your computer with your micro usb cable. Your phone have to be powered on.
Be sure every pieces of hardware are detected and installed correctly.
As you can see, this phone is not just detected as an ADB device, or as a mass storage device.
It actually have an internal serial port to usb adapter !
In other words that means this processor provide a way to flash his nand very easily even if it is fully bricked. It's a rare and pretty good feature you don't see that often. In fact, most of the time you have to solder a real serial port yourself on the phone motherboard, then have to use a Serial to USB adapter to have this level of access to the hardware.
So yes, back to tutorial.
Now you will have to unplug your phone and turn it off.
You have to download the debug tools, you can download them here: http://www.mediafire.com/download.php?rngukh111vqfr8h
First you have to start the channel server, you will have to disable your firewall for this app, it's because this tool use a network protocol to communicate with the other tools.
Then open ResearchDownload.
ResearchDownload is a weird flashing utility, it can open a .pac firmware file and can make a .pac out of .img files. You also can flash .img files and that's what we will do. But unfortunately it can't make a full backup ... So be careful !
The cog logo is here to let you open a .pac file. We don't need that as we probably don't have it.
The "two cogs logo" let you configure the flash utility.
Click on this to bring a new window.
On the download settings window, click on select product then choose your type of phone. (SC8810 or SC6820, it doesn't really matters if you take the wrong one out of those two.)
Then uncheck "Select All Files" as you don't have any of theses.
You can see FDL1 and FDL2 are still checked, and you don't have those files ...
As they are needed to start the Flash utility, we will have to find them.
I came across only 3 different FDL1 files, but for theses FDL1 it seems every phone have his own FDL2.
You will have to find the ones that work for you.
Here is an archive of nearly every FDLs available: http://www.mediafire.com/download.php?c6q2gxobccv32oj
Choose one FDL1, and one FDL2 located in the same folder. (you can choose a File with a right click on the FileName blank space in front of FDL1)
Click on OK.
Then click on the "Play button" saying start download.
It may show some warning, it's not a problem.
Now, press Volume Down on your phone, then you have to plug it on the USB Port, still holding the button.
You can release the button when the flash begins.
You may have to press an other button than Volume-. Some phones are reported to use the Home Button instead.
You may also have to remove, wait a while, and reinsert the battery before holding volume- or after the flashing procedure to be able to start the phone.
If ResearchDownload shows you an error or timeout, try another set of FDLs Files. Keep trying until you find one pair that work !
If it works the flashing process should start right away. Just a millisecond after Windows have detected and initialized the device when you plugged it.
When you have the right FDLs, you can go to the next step, flashing something useful ^^ (we haven't flashed anything as of now, just been searching for a compatible flashing bios)
If your working FDLs folder does not have the name of your phone, please tell me what phone you have and what FDLs you used so I can rename them.
4.2 - Using ResearchDownload to load CWM (Clockwork Mod)
Do exactly as said before, but check the "Recovery" checkbox on Download Settings. and choose one of theses CWM images:
* http://www.mediafire.com/download.php?y2f7aaan4b00l1m - Feiteng GT-A7100 and probably more Feiteng devices.
* http://www.mediafire.com/download.php?lg7m6v49efzpnjk - 6500-TV or S560
* http://www.mediafire.com/download.php?6xn977jjsuusjan - N9300 (I9300 Clone)
* http://www.mediafire.com/download.php?d68wc334qn47tdd - S930 or N8820
* http://www.mediafire.com/download.php?xem49dy5dh99ml0 - 5830, S5830, Q5830, Q206 and GT-N9300 (maybe more)
* http://www.mediafire.com/download.php?bdl1qr7orsj4ebr - extracted from a random SC6820 that I don't remember
* http://www.mediafire.com/download.php?6g1t6057p6c8wpt - i9720+
* http://www.mediafire.com/download.php?adfwq6b5268qb58 - S9300 (SC6820A S3 Clone)
When you flashed one successfully, try to boot on recovery (Usually by holding Volume- while holding the power button until the screen light up).
If your device is not listed or the one for your device doesn't work, try them all, even if your phone is SC6820 and the recovery was made for SC8810, if none are working, we will have to flash the entire system partition, which is a lot more difficult and dangerous ...
Download this patch: http://www.mediafire.com/download.php?131nsw87afzwb5v
Put it on the root of your SD Card.
Now you will have to boot on CWM, remember, he is on the same key combination than the old useless recovery was.
You can also try this command with adb:
Code:
adb reboot recovery
Now it's the perfect time to do a full backup of your firmware with CWM, so please do so, that can come in handy. (please go to the end of this tutorial after rooting your phone to know how to make a FULL backup. CWM will only make a partial one.)
choose apply update.zip
Choose the file you have put on your sd card before
Apply it then reboot.
This update.zip have pushed everything needed to root your phone in the right place, you should be rooted now !
If you have an error like:"Can't mount /sdcard" you may have to try with another SD Card and be sure your SD Card if formated as Fat32.
4.3 - Using ResearchDownload to load a modified system partition image
Now we are in deep **** ! This can be tedious ... You will need to drink a lot of coffee, then you will probably pull your hair off, but it's possible to root every single Spreadtrum devices this way !
Please follow the instructions down bellow on how to "5 - Create a rooted system partition image"
When you have done your Rooted system partition image, reboot on Windows, then flash it like that:
Do exactly as said on the paragraph on how ResearchDownload works, but check the "System" checkbox on Download Settings, and choose your modified system.img file to flash it on the device.
As it is still not tested at all, you will have to pray some kind of Spreadtrum God and hope it will be successful ...
The first boot after the flash can be very VERY long. It's perfectly normal.
After the flash is done, please make a full backup (see bellow how you can do that), so I can make a Clockwork recovery partition working with your phone.
You may need to flush your data partition with CWM to avoid some crazy bugs after the flash. You will have theses bugs because of the partitions realignment that might occurs as a result of using a slightly different FDL set as the manufacturer.
Don't even try to do a factory settings reset before installing CWM, as I don't know what monster can lie ahead if you do a factory reset without any working recovery installed
(If your phone doesn't boot after the flash, it is possible to flush the data and cache partition with ResearchDownload. I will explain it, if needed !)
5 - Create a rooted system partition image
Please always try the CWM method first ! There is no risks at all to destroy your phone if the recovery is not working. Here we are making a new system image to flash on the system partition, this partition contain the Android operating system. I will try to explain everything as good as I can, but if you make a mistake, if you don't read my warnings, you can brick your phone very easily !
That will be difficult ... And you will have to use a Linux computer, or Linux in Virtualbox, or in a Live CD, basically you will need Linux somewhere on your computer ^^
Why ? Because we will have to preserve unix permissions on an extracted tar archive ! Trust me, you will probably brick your phone if you do that on windows ...
#Install ADB
Code:
sudo apt-get install android-tools-adb android-tools-fastboot
#Configure ADB
Code:
mkdir ~/.android
Code:
echo 0x1782 > ~/.android/adb_usb.ini
#Start the ADB server
Code:
sudo adb kill-server
sudo adb start-server
#Just let's check just in case if your device is already rooted
Code:
adb shell su -c id
Possible answers:
uid = 0 (root) gid = 0 (root) - your phone is already rooted ! (if you haven't noticed it, it's because superuser.apk is not installed, so just push it and install it via ADB and you are rooted !)
SU: Permission denied - You are not rooted ... Good luck then !
#Now we will backup the system partition !
Code:
adb shell tar -cf /mnt/sdcard/system.tar system
Please pay attention to the errors !
There will be missing files, and we will have to add theses by ourselves after the backup to pretend to have a full backup.
Here is the archive for the known missing files: http://www.mediafire.com/download.php?fm1z5ujc75bg268
If you have more than theses:
Code:
tar: can not open 'system/etc/dbus.conf': Permission denied
tar: can not open 'system/etc/bluetooth/audio.conf': Permission denied
tar: can not open 'system/etc/bluetooth/auto_pairing.conf': Permission denied
tar: can not open 'system/etc/bluetooth/input.conf': Permission denied
tar: can not open 'system/etc/bluetooth/main.conf': Permission denied
tar: system/lost+found: Permission denied
tar: Error exit delayed from previous errors
Then you should just give up, or tell me so I can send you the missing files.
Note: Lost+found is not important, it's just a folder automatically created by Linux to collect any corrupt files.
#Now we will pull this nearly full backup to our computer. Please keep it preciously somewhere secure.
Code:
adb pull /mnt/sdcard/system.tar
#Warning, theses next steps have to be made ONLY on Linux on an ext2/3/4 partition ! Please never attempts to do this on Windows or On Linux on a FAT32 partition.
#untar the archive
Code:
sudo tar -xvpf system.tar
#now we will restore the files we have not been able to backup.
#Download this archive if you haven't done this before: http://www.mediafire.com/download.php?fm1z5ujc75bg268
#Then extract it on the same folder as you extracted your system.tar file with this command:
Code:
sudo tar -xvpf btdbus.tar
#Now it's time to add the root utilities, you can download them from here: http://www.mediafire.com/download.php?v69nm172heos17o
Code:
sudo tar -xvpf root.tar
sudo cp Superuser.apk system/app/Superuser.apk
sudo install -m 06755 su system/xbin/su
#Now we will get rid of this virus ! (the file name can be something else. Like caivs.apk, or some random numbers at the end)
Code:
sudo rm system/app/eyuSales_20121116.apk
#And now you will have to make a flashable system image with this tool, included in the root.tar archive
Code:
sudo ./mkyaffs system system.img
#Now you can reboot your phone in fastboot or use researchdownload to flash your new System image.
6 - Do a full nand backup
Here is how to do a full nand backup of your beloved Spreadtrum: http://forum.xda-developers.com/showthread.php?p=39270468
7 - Don't forget to remove to caivs Virus
When you are rooted, you can remove the Virus or any preinstalled apps using Link2SD.
I suggest you to remove everything you have preinstalled if it is available on the Google Play Store (except the keyboard or the launcher !!!). For example if you have an old version of ES File Explorer on your phone preventing you from updating it, you can remove it safely, then install the updated version from the the Play Store.
Never try to remove something that you don't know what it is !
For the Launcher or keyboard. You can remove them only if you installed a new one on the System partition and tested it successfully !

Data missing?
First of all, thanks a lot for tutorial! Unluckily there is missing the data that i should copy back into the tar and then the img-file. Could you upload the btdbus.tar and the root.tar?
Thanks again, have a nice day!

I'll try to load CWM even though at the moment I can only get into recovery. I have the exact same model as H_Bler's which is why I've been focusing more on his thread. From your description on how to access fastboot, I assume that it's the diagnostic mode when UpVol + Pwr is pressed. I never saw anything that said fastboot. The only thing unusual when I was going through the menus was I always got an error when I try the 4th or 5th option. Unfortunately, I can't really try it again because I can't access it anymore. That goes without saying the I can't work with IMG files as well.

Well the thing you have when you push up and power is the system test menu. It's located on the android system partition. It's not fastboot.
Fastboot should be something that says "Fastboot" in red letter, or something else unusual.
If you have not fastboot you should use Spreadtrum Researchdownload to flash your phone, I will write the tutorial about it soon.
I really can't link you the thread on the russian forum, first because it will probably confuse you, and also because it's spread everywhere on so many threads it's unbelievable ... That's why I'm doing this centralization work for you ^^
I will post a list of ROMS for recovery purpose. Your phone seem to be bricked. I don't know how you've done it (I really want to know what you phone is and how you've bricked it, that will help me to write the warnings necessary to avoid such cases).
I have 14 roms for Spreadtrum devices, maybe one will work for your phone.
I just want to know what your phone is ^^ Please tell the name of your phone on your posts everyone and if you know how to find it, the exact name of your firmware.
PS: I will upload the patch soon, I'm just searching for a file hosting service that will keep it up and not erasing it 2 hours after I uploaded it ^^
EDIT: Link to the update.zip for rooting you device via CWM added.
Tutorial updated: Spreadtrum debug tools method added.
It may now be possible to root even Spreadtrum devices without Fastboot mode available.
Please feel free to tell me if it works !

Question
Dear Spreadtrum Master!
Please, can you help me with this problem:
I have a Star I8160 phone with Spreadtrum 6820 and 256 MB ROM. It seems, that everything is working fine, the ROM and the phone is fast, and cool. But when i try to use the phone as a phone, i talk to the phone, and the others just only hearing pieces of my sentences. Sometimes the phone is very-very silent, i need to shout for the others to hear. I thought, that this is a microphone problem, so i replaced the microphone. But nothing changed. I had 2 phones from this type, and both produces the same fault, so i think maybe the problem will be with the ROM. What do you think, is it possible? If so, can i replace my normal rom, which is DM_BASE_12A_w12.43 (sc6820_modem) 11-02-2012?
question
Hi ElectronikHeart, i need help
I have a feiteng a7100, and i flash a rom with ResearchDownload.exe, in the flash operations tab i choose the option to erase all flash. Now i have a brick phone. Do you have a copy of nv.bin? Do you know how to recover from it? how can i reflash nand?
thanks

The Master hasn't been in the past few days so I'll try to answer your issue as best I can.
Usually, the phones are designed for a specific region/country. It's possible that your ROM was built for a different one. How sure are you that the ROM which you are replacing it with will work for you? (I assume that you have a backup and you know how to load ROMs) Also, you might want to try editing the build.prop it increase/maximize reception.
To be honest, this is actually a complicated approach. From what you said, it seems that you've made other troubleshooting steps on your own. Since you really did not mention all of them I'm basing my response on what you said.
Let's try to stick to the basics first. Why did you replace the microphone in the first place? If the same issue happens with 2 other phones from this type, I don't think the mic is the problem. Also, does this mean that you can hear them fine, but they have a hard time hearing you? Have you tried using the stock sound recorder on your phone? Is it also choppy? Have you tried using Skype? You don't really have to call anyone, you just need to make a test call.
When using the device as a phone (eg. making calls, sending SMS, MMS, or connecting to the internet using EDGE or 3G), you're actually relying mostly on your carrier/service provider. How many signal bars do you get? The easiest way to test signal related issues would be by using a different SIM or using a different phone. (When you try a different phone, I suggest using a GSM one - the ones that can only make calls or do SMS.) It's highly possible that there's already something wrong with your SIM.

ElectronikHeart hasn't checked in the past few days, so I hope you don't mind me butting in.
When you say brick, does it mean that you don't even have recovery mode? If you don't, try to see if you can put CWM. Once successful, you can try to use the A7100 ROM if your original one was a mt6515_c910_ht_en_4.0_v01 rom using the update.zip

Dear Spreadtrum Master!
Please, can you help me with this problem:
I have a Star I8160 phone with Spreadtrum 6820 and 256 MB ROM. It seems, that everything is working fine, the ROM and the phone is fast, and cool. But when i try to use the phone as a phone, i talk to the phone, and the others just only hearing pieces of my sentences. Sometimes the phone is very-very silent, i need to shout for the others to hear. I thought, that this is a microphone problem, so i replaced the microphone. But nothing changed. I had 2 phones from this type, and both produces the same fault, so i think maybe the problem will be with the ROM. What do you think, is it possible? If so, can i replace my normal rom, which is DM_BASE_12A_w12.43 (sc6820_modem) 11-02-2012?

Hi,
I had the same problem with one of mine. You just have to use a diagnostic tool from Spreadtrum and adjust the microphone amplification level. I will start a thread on that subject and link it there.
It seems to be a very common problem with Spreadtrum phones, but it is, most of the time, very easy to fix.
edit: here is the link: http://forum.xda-developers.com/showthread.php?p=38731407
WARNING: Don't ever flash if you don't have a working copy of the original firmware somewhere (a complete backup that you have tested your ability to flash back) The first step to do a complete backup, if the manufacturer don't want to send you the firmware, is to successfully root your firmware)
Don't flash if you have a microphone problem, nothing good will happen, this problem is not firmware related AT ALL.

Hi ElectronikHeart, i need help
I have a feiteng a7100, and i flash a rom with ResearchDownload.exe, in the flash operations tab i choose the option to erase all flash. Now i have a brick phone. Do you have a copy of nv.bin? Do you know how to recover from it? how can i reflash nand?
thanks

Oh god ! Why have you checked that option ^^
I may be able to dump my nv.bin file from the a7100 I just bought. (If I recall correctly, the nv.bin contain the imei so I will have to edit it to use your imei instead, imei are written in the battery compartment)
Can you try flashing it a second time entirely, It's possible that your uboot partition (what manage the early time boot operations), is not flashed properly.
Even without the nv partition you phone should be able to boot android, you will just not be able to use the phone as a phone. (make a call and everything)
Try with a better micro usb cable, Chinese ones can be very cheap and corrupt data on the way to the phone.
If your phone is still able to flash using ReasearchDownload that is.

Please if you have rooted your phone using this method, and can't use the CWM method, that mean I can do a CWM that work on your device !
Now that you are rooted, you can make a full backup of your phone with ADB !
#open adb shell:
Code:
adb shell
Code:
I still have to explain this if someone needs it
Then send me you boot.img file and I will send you a recovery.img that you can flash to your recovery partition.
That will help new users to root a lot faster the same phone as you, and will make your life easier is you have to restore a backup.

I have also the same kind of chinese android phone, having a model # S930 with the same cpu chipset SP8810 (aka. samsung galaxy s3 clone), i've successfully rooted my chinese android phone, and installed some very usable apps like link2sd & titanium backup pro, i want also to have a full backup of my phone using your methods & ideas, can you help me? where can i find my boot.img so that you can make me my recovery image for my phone? my phone don't have any compatible clockworkmod recovery, but it have a native recovery mode option which work on an update.zip or fastboot....i hope you can help me make my phone recovery image with a rooted features... Thanks!

So, you already have tested every recovery already posted ?
To make a backup of your boot.img, you will have to do a full backup manually using the Android shell. I will make a tutorial about this, and link it here.
It's pretty easy as you already rooted your phone.
When you have your backup I will, post a recovery.img file suitable to your phone.
Please keep an eye to this post. I will post the tutorial very soon.

I just bought my A7100, so you will need to wait 2 weeks for me to dump it. Maybe you should try asking to the guy who have made the rooted rom for the A7100 ?
I will, none the less, make a full backup of my phone as soon as I receive it.
hi, tried to search everywhere but to no avail soo far.. does anyone knows if there is an existing root guide for LG G4 Beat? its sort of a diff model but there's no sub for it so i guess ill put it at here since its still under G4 family.. :/
Do you have Android 5.0 or 5.1 installed?
First of all. Before you start to try root, download the kdz file for your phone.
The kdz is needed if something went wrong (e.g. phone not booting).
You can use the LG Flash Tool to flash the kdz to a bricked phone.
Use this link with your IMEI:
Code:
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI
If it works, please post the download link for the "kdz".
Or better post the output too, but delete your IMEI!
Your link will only work if you type:
csmgdl.lgmobile.com/dn/downloader.dev?fileKey=
and then add the rest of your url instead of the given link.
It's worth trying. You need to get a partition layout. Then @autoprime will give a full command to run in DL mode for dumping the system image, and flashing it once it's been injected with root. I can inject it for you once you have the system.img dump.
I wrote an guide how you can extract the GPT and calculate the dd parameters:
[How to] Determine dd Parameters For All LG G4 Models
http://forum.xda-developers.com/g4/h...lg-g4-t3184867
Do you know how to work with linux?
Please post the outputs of gdisk into a HIDE and CODE tag. Thank you.
Maybe you are a advanced user and can Inject root yourself with the autoroot.sh method (Inject_Root_G4.zip)?
Or do you need help?
I think you have Android 5.1.1 installed, so it is not possible to use Kingroot to root your device. Is that right?

Ok, well done. Is 10b the same version as currently installed on your device?
Some other details would be interesting:
Do you have an unbranded device?
Where did you buy it / where do you live? (country)
Are you an advanced user? Do you know how to work with linux?
The next steps will be:
Calculate your dd parameters and backup your system partition into a img file. Read my guide:
[How to] Determine dd Parameters For All LG G4 Models
http://forum.xda-developers.com/g4/h...lg-g4-t3184867
Please post the outputs of gdisk into a HIDE and CODE tag.
Post your calculated dd parameters, so that we can verify it.
IMPORTANT: Keep the original (unchanged) system.img on your computer (zip it).
Then:
Copy the img file to a linux system and mount it. Create a testfile (test.txt) on the mounted system partition.
Copy the img file back to your phone and try to "dd" it back over your system partition.
Check if you see the testfile on your system partition.
If that worked you have successfully overwritten your system partition.
Then:
Try to inject root with the Inject_Root_G4.zip on your linux system.
Copy the new img file to your phone and "dd" it over your system partition.
Please ask if you are not 100% sure what to do.
You are responsible for what you are doing with your device.
Backup all your data (photos, videos, messages...) before going one step further.

what do u mean 10b?
not really unbranded i guess? its a mid-tier version of the LG G4.. this is the phone.. http://www.lg.com/sg/mobile-phones/lg-G4-Beat
dont think its out at the US yet
bought it at Singapore as i recontacted my phone
nope i dont know how to use linux and im %100 not sure what to do :crying:
Ok so you are not a advanced user?
10b is the version of the kdz file. Goto Settings->Phone info->software version on your phone and post your software version.
First of all: It is not possible to root your phone without linux!
You don't have to install a linux on your computer (physically) but at least in an virtual environment (virtualbox, vmware player) or as a live distribution.
What you can do without linux is try to extract the GPT.
Which OS is installed on your computer (Win 7, 8, 10)?
Download the LG_Root.zip from
http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772
It contains the Send_Command.exe
You need this tool to open a special console when your phone is in download mode.
Do you know this tool and how to enter the download mode?

Root your LG G4S (Model H735)
Tested on Andriod 5.1.1.
Thanks goes to @konsolen for sharing the method to open up the port (see appendix in this post) and to @dominik-p for his guide to determine dd parameters (you won't need this to root with the method described, but you can back up your phone if you're worried). And most importantly, thanks to the author of SuperSU for his excellent script updater-binary which worked pretty much out of the box, with only a few workarounds needed (which is what the instructions below do).
First, a few general notes:
The supersu.zip included in this package is version 2.46.
SuperSU can be downloaded here: http://download.chainfire.eu/supersu
If you want to use a new version, just put the zip file in this directory and rename it to "supersu.zip" (delete the old one in this package first of course).
The busybox binary in this package was used successfully to unzip in the LG G4s H735 (Android 5.1.1).
Some time it should maybe be ensured that this is the newest version. Same holds for Send_Command.exe and adb.exe (and attached libraries).
This script uses the "update-binary" script of the SuperSU package to install it on your phone.
The scripts I attached prepare for it to be called (hopefully) successfully.
Instructions to root
Preparation
You MAY want to create a backup of your system beforehand, in case things go wrong.
This is optional, so if you don't want to do this, you may still rely on the .kdz file (see Appendix below) to restore your phone if things go wrong.
You need to calculate the dd parameters and then backup your system partition into a .img file.
There is an excellent guide by @dominik-p for how to determine your individual dd parameters:
http://forum.xda-developers.com/g4/help/how-to-determine-dd-parameters-lg-g4-t3184867
Keep a copy of your system.img somewhere safe, you can use it to restore
your system if something goes wrong.
Enabling developer options and getting the tools
First, enable developer / debugging mode on your phone:
Navigate to Settings > About Phone > scroll to the bottom > tap Build number seven (7) times.
You'll get a short pop-up in the lower area of your display saying that you're now a developer.
Then, go back and now access the Developer options menu, check 'USB debugging' and click OK on the prompt.
Note: You have to enable USB debugging before plugging your device in to the computer. Unplug device then try to enable USB debugging.
On your computer, install Install and Use ADB (the Android Debug Bridge Utility). Also, download LG Flash Tool.
You can find out how to do both by searching google for it.
Step 1.
Connect your phone via USB (not in download mode yet, just normal).
Then, run Init_Root.bat in order to copy the essential files over to internal storage.
You may do this either by 1) double clicking the file, or 2) executing it from the windows command line.
For Option 2): Open a command line in the folder where you extracted this package. To do this, hold shift while right clicking in the folder opened in the Windows Explorer and select "Open command window here". Then, type
Init_Root.bat
Step 2.
Reboot your phone in download mode and ensure it has opened the port to send commands in download mode.
The port is open if it's displayed on the phone's screen in green letters, like
COMX
(with a number instead of X).
On my LG H735 it was necessary to use "LG Flash Tool 2014" http://lgflashtool.com/ to open the port. So if you don't have the green letters, see instruction pasted below (appendix) on how to open the port.
Step 3.
Open a command line in the folder where you extracted this package. To do this, hold shift while
right clicking in the folder opened in the Windows Explorer and select "Open command window here".
Open a command shell to your phone by typing (replace X with the number displayed on your phone) by typing:
Send_Command \\.\COMX
You should be set to root if the following works:
Typing "ls" returns a long list of file and folder names.
Typing "id" should give you someting like that:
uid=0(root) gid=0(root) context=u:r:recovery:s0
The important bits are the "(root)" uid and gid.
If any of the above is not the case, it will not work, you may search for help in the forum.
Step 4.
Execute the commands below (without the numbering of course).
1. mv /data/local/tmp/busybox /sbin/busybox
2. chmod 755 /sbin/busybox
3. mkdir /tmp
4. mkdir /tmp/supersu
5. /sbin/busybox unzip /data/local/tmp/supersu.zip -d /tmp/supersu
6. mv /data/local/tmp/supersu.zip /tmp/supersu/
7. sh /tmp/supersu/META-INF/com/google/android/update-binary dummy 1 /tmp/supersu/supersu.zip
(Note: Not all commands above may be needed, but this is the conservative approach)
Recommended:
Do sanity checks to see if it's doing its job as expected.
After command 2, type the command ls -l /sbin/busybox to check for sanity.
It must return a line like this (with your own date and time):
-rwxr-xr-x shell shell 1048328 <date> <time> busybox
Command 5 must print several lines containing "inflating" messages, similar to this:
Archive:
inflating: META-INF/MANIFEST.MF
...
Command 7 prints lines like this, and other status messages afterwards:
**************
SuperSU installer
**************
...
Step 5.
Your phone should now be rooted if it all worked ok.
You may now type
LEAVE
to reboot your phone.
Happy rooting!
Troubleshooting
If it doesn't work, for example you phone may be stuck on the boot process displaying the LG logo, then you can use Flash Tool to restore your phone. Use instructions below (how to boot the phone into download mode), but don't pull the USB cable, and just let it run its course. This should restore your phone.
If for some reason this hasn't worked, you may try to "dd" back your system .img which you may have created in the preparation step.
Appendix
How to boot the phone into download mode and open the port
a) Boot the LG G4s in download mode. To do this, first switch it off completely and disconnect USB cable. Then, hold the Volume Up button, and while you keep holding it, plug in the USB cable.
b) Start the LG Flash tool and load the .kdz for your phone. We won't actually complete the flashing, you only need it to start the process, but you should use the kdz for your phone nonetheless.
You can check for your kdz on this link, pasting your IMEI instead of YOUR-IMEI in the link below.
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=YOUR-IMEI
I did not find any for mine there, but I did find it on
http://devtester.ro/projects/lg-firmwares/
Which brought me to this link where I could find mine:
http://pkg02.azure.gdms.lge.com/dn/downloader.dev?fileKey=FW703UV132GQAUP7A0ED99N/H73510c_00.kdz
c) Now this is very important: Watch your phone while the .kdz is being flashed by the flash tool.
(the flash tool may complain about error connecting to the update server, but you can ignore this with "ok").
As soon as the green letters show up, UNPLUG THE USB CABLE!
The percentage on your phone has to be 0% still (never mind about percentage in the flash tool, it may not even display it).
Then, kill the Flash Tool with the Windows Task Manager (Ctrl+alt+delete).
When it's closed, you can plug your phone back in.
It's now in download mode with open port.

The supersu.zip included in this package is version 2.46.
SuperSU can be downloaded here: http://download.chainfire.eu/supersu
If you want to use a new version, just put the zip file in this directory and rename it to "supersu.zip" (delete the old one in this package first of course).
The busybox binary in this package was used successfully to unzip in the LG G4s H735 (Android 5.1.1).
Some time it should maybe be ensured that this is the newest version. Same holds for Send_Command.exe and adb.exe (and attached libraries).
This script uses the "update-binary" script of the SuperSU package to install it on your phone.
The scripts I attached prepare for it to be called (hopefully) successfully.
Instructions to root
Preparation
You MAY want to create a backup of your system beforehand, in case things go wrong.
This is optional, so if you don't want to do this, you may still rely on the .kdz file (see Appendix below) to restore your phone if things go wrong.
You need to calculate the dd parameters and then backup your system partition into a .img file.
There is an excellent guide by @dominik-p for how to determine your individual dd parameters:
http://forum.xda-developers.com/g4/help/how-to-determine-dd-parameters-lg-g4-t3184867
Keep a copy of your system.img somewhere safe, you can use it to restore
your system if something goes wrong.
Step 1.
Connect your phone via USB (not in download mode yet, just normal).
Then, run Init_Root.bat in order to copy the essential files over to internal storage.
You may do this either by 1) double clicking the file, or 2) executing it from the windows command line.
For Option 2): Open a command line in the folder where you extracted this package. To do this, hold shift while right clicking in the folder opened in the Windows Explorer and select "Open command window here". Then, type
Init_Root.bat
Step 2.
Reboot your phone in download mode and ensure it has opened the port to send commands in download mode.
The port is open if it's displayed on the phone's screen in green letters, like
COMX
(with a number instead of X).
On my LG H735 it was necessary to use "LG Flash Tool 2014" http://lgflashtool.com/ to open the port. So if you don't have the green letters, see instruction pasted below (appendix) on how to open the port.
Step 3.
Open a command line in the folder where you extracted this package. To do this, hold shift while
right clicking in the folder opened in the Windows Explorer and select "Open command window here".
Open a command shell to your phone by typing (replace X with the number displayed on your phone) by typing:
Send_Command \\.\COMX
You should be set to root if the following works:
Typing "ls" returns a long list of file and folder names.
Typing "id" should give you someting like that:
uid=0(root) gid=0(root) context=u:r:recovery:s0
The important bits are the "(root)" uid and gid.
If any of the above is not the case, it will not work, you may search for help in the forum.
Step 4.
Now you have two options:
#Step 4, Option 1 (recommended to try)
Just run the script and you should be done.
Type:
sh root_lgh735.sh
The script contains all commands I (and other people) used to successfully root the phone.
However we have all used option (2) below, so the script itself has not been tested yet,
though it's very simple (feel free to open it with a text editor to look at it).
You can try to run it, and if it's not doing what's expected you can still go to Option 2
and fix things up.
It will have worked if:
It prints several lines containing "inflating" messages, similar to this:
Archive:
inflating: META-INF/MANIFEST.MF
...
It prints 3 lines like this, and other status messages afterwards:
**************
SuperSU installer
**************
....
If it has done that, reboot your phone and you should be set.
If not, do the commands manually as in Option 2.
Please: If the script worked for you, report it in this thread, so I can simplify these instructions here! Thanks for your help :cyclops:
#Step 4, Option 2:
Execute the commands directly (proven to work on several phones).
Type the commands below (without the numbering of course).
1. mv /data/local/tmp/busybox /sbin/busybox
2. chmod 755 /sbin/busybox
3. mkdir /tmp
4. mkdir /tmp/supersu
5. /sbin/busybox unzip /data/local/tmp/supersu.zip -d /tmp/supersu
6. mv /data/local/tmp/supersu.zip /tmp/supersu/
7. sh /tmp/supersu/META-INF/com/google/android/update-binary dummy 1 /tmp/supersu/supersu.zip
(Note: Not all commands above may be needed, but this is the conservative approach)
Recommended:
Do sanity checks to see if it's doing its job as expected.
After command 2, type the command ls -l /sbin/busybox to check for sanity.
It must return a line like this (with your own date and time):
-rwxr-xr-x shell shell 1048328 <date> <time> busybox
Command 5 must print several lines containing "inflating" messages, similar to this:
Archive:
inflating: META-INF/MANIFEST.MF
...
Command 7 prints lines like this, and other status messages afterwards:
**************
SuperSU installer
**************
...
Step 5.
Your phone should now be rooted if it all worked ok.
You may now type
LEAVE
to reboot your phone.
Happy rooting!
Troubleshooting
If it doesn't work, for example you phone may be stuck on the boot process displaying the LG logo, then you can use Flash Tool to restore your phone. Use instructions below (how to boot the phone into download mode), but don't pull the USB cable, and just let it run its course. This should restore your phone.
If for some reason this hasn't worked, you may try to "dd" back your system .img which you may have created in the preparation step.
Appendix
How to boot the phone into download mode and open the port
a) Boot the LG G4s in download mode. To do this, first switch it off completely and disconnect USB cable. Then, hold the Volume Up button, and while you keep holding it, plug in the USB cable.
b) Start the LG Flash tool and load the .kdz for your phone. We won't actually complete the flashing, you only need it to start the process, but you should use the kdz for your phone nonetheless.
You can check for your kdz on this link, pasting your IMEI instead of YOUR-IMEI in the link below.
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=YOUR-IMEI
I did not find any for mine there, but I did find it on
http://devtester.ro/projects/lg-firmwares/
Which brought me to this link where I could find mine:
http://pkg02.azure.gdms.lge.com/dn/downloader.dev?fileKey=FW703UV132GQAUP7A0ED99N/H73510c_00.kdz
c) Now this is very important: Watch your phone while the .kdz is being flashed by the flash tool.
(the flash tool may complain about error connecting to the update server, but you can ignore this with "ok").
As soon as the green letters show up, UNPLUG THE USB CABLE!
The percentage on your phone has to be 0% still (never mind about percentage in the flash tool, it may not even display it).
Then, kill the Flash Tool with the Windows Task Manager (Ctrl+alt+delete).
When it's closed, you can plug your phone back in.
It's now in download mode with open port.

Have twpr or cwm recovery to install xposed??
I can confirm is working on LG G4 LG-H735P (Latin America version), thanks!
anyone tried updating? just got a system update notification from my phone lol dk if i should update now or not
Good question! I didn't try it yet. Think it should be ok, but if it isn't, you can just root again I guess

I could not root my phone, what kdz file did you use??
Backup problems
Hello,
Coming from a Nexus 4, I bought a G4S last month.
I want to do my first root in order to manage the storage, like jen.magnolis talked about.
In case of a problem (bootloop or brick), I need to be able to restore. I don't really mind about restoring my datas, a factory reset would be enough.
But I don't undestand how i can get the system.img without being rooted ? It seems that I can get a "backup.ab" file using adb. Will it be enough to restore in case of brick ?
I also looked about kdz files, but mine doesn't seem to be available. I have a LGH735 (buyer = FRA, suffix = AFRATS, ...). Will it work if I use the one you provided in your post ?
Thanks for your help !

I got the same model phone, but I can't find the .KDZ file for it anywhere. Could you post a link to the one you used please?
Excellent step-by-step guide. Should set an example for other "step-by-step guides" which exclude crucial information ("everybody knows lösfhgaeilurhg has to by typed between these steps here, I shall not mention it" )
Thanks a ton Worked on my LG G4S a.k.a H735 like a charm.
Cheers!

"phone appears to be rooted, will not be updated" - Hiding root did not help, any simple suggestions but total unrooting?
Wanted to upgrade from 10c to 10d...
Cheers!
Doubts.
Hi everyone!
I just cant find my .kdz file! The phone i want to root its a G4 H735AR, im wondering if there are some compatible .kdz that i can use. Im affraid it might get bricked or something...
BTW i¨ve tried the rootworm.bat method and it didnt work. And when i try to open the COMX port, the lg flash tool always crushes and shuts down.
Works!

So, i made it! It works in the H735AR!! The problem with the flash tool was that i was trying to use it without any KDZ file!! I've used @konsolen .kdz and achieved to open ports, and then continue with the rest of the tutorial without trouble.
Thank you so much! Its a great phone, but with so little internal memory is a waste.

ya u just update thru lg bridge.. once updated it will be unroot tho so u have to root it back same method as u did before.. and if you use link2sd it dosent matter after root ur link2sd can just reboot and re-read ur partition without needing to wipe and re-partition
It's working in H736P! Thank you só much!
Enviado de meu LG-H736 usando Tapatalk
For people in Brazil that has H736P, to open ports, is necessary the kdz file to use in LG Flash Tool.
Galera do Brasil, consegui rootear o LG G4 Beat usando esse tutorial porém tive que baixar o arquivo kdz pro H736P pra executar o LG Flash Tool. Cuidado ao usar o LG Flash Tool, assim que aparecer a porta COM na tela do telefone, arranca o cabo USB do computador.

Bricked my razer a while back reinstalling the stock firmware. The cable unplugged from the phone and corrupted the storage. Cant enter recovery or bootloader. But according to some resources that i came across while doing some research, im able to interface with the device using the qualcomm hs-usb protocol. With that im able to directly access the devices storage. If anyone is willing to help, what id need is for you to wipe your device clean, and run these commands
Adb shell
Su
dd if=/dev/block/mmcblk0 of=/storage/sdcard1/backup.img bs=512 count=30535646
From there id be able to delete the partition table, and copy the devices storage config from the backup. Once thats established id be able to access bootloader recovery and system.
If anyone is able to help, id really appreciate it
Thanks
i too have done the exact same now stuck with a brick hope someone can help

Nope nothing yet, we need either emmc development files for the phone, no likely to find. And with the qualcomm tools the corrupted storage can be re partitioned and again be written to.
However if someone with a working razer was to wipe the device clean, and dump partition info. Then the images can be written to the device, over writing the damaged partitions.
Black screen on my razer phone. can't access download or recovery. any help will be greatly appreciated. the computer makes a sound when I plug in the razer phone.

Your razer is in a state known as EDL. I5s the qualcomm Emergency Download mode. Used to program your emmc storage. That is exactly what the few of us are experiencing, however with no owners of the device willing to share a default wiped image of their emmc, there is no way for us to remap the partitions appropriately in order to once again flash and access the bootloader.
If you could let me know how one would do it I might be able to help you before I sell my razer phone
Thank you, if you restore your phone back to factory settings, connect to pc via adb and run the command in the initial post. That command should (from what i read elsewhere) create a full backup of the partitions on your device. If you are successfull and are able to share through some cloud storage such as dropbox or something of the like, i should be able to restore my razer.

im guessing i will need root to run those commands, atm i am performing a full nandroid backup of everything before i do the reset, my phone is rooted and has twrp installed on both a and b partions
extracted the files, the img is 13GB so gonna compress it before i upload it, hopefully it should work but will have to be tomorrow now
uploading the file now
ok done, heres the link
http://www.mediafire.com/file/j3j6pp3ym161t0q/backup.7z/file
you will need 7zip to extract it which you can get from here for free www.7zip.org

hi xda member dtronics has very kindly uploaded a complete back up approx 13gb
file.do you know how to use this to restore/repair our phones?.
Excellent, i will take a look and see if i can push it to the device in edl mode. The thread has been dead for a while, so it may take a while for me to review all the previous resources that led me to the point where i had posted this thread.
Thank you so very much!
This is the article I was using to attempt salvaging my phone.
https://www.droidsavvy.com/unbrick-qualcomm-mobiles/
Unfortunately I am in the EDL mode where my device storage is not recognized, so I am unable to tamper with it until the razer phones flash programmer or firehose files have been leaked.
Hopefully someone else may have success resurrecting their device using dtronic's backup and or with the information provided in the link.
Thank you any and all of you who have contributed or followed the thread. But my trail ends here unless the flash programmer files are somehow made available.
Unfortunately sadly I too couldn't work out a way to flash or recover razer phone with the upload from dtronics.thank you to all involved,but I think it's time to chuck the old razer in the bin.this is my first ever failure or perm bricked device since I started rooting etc with the HTC wildfire.
?
Tried Klinik handphone medan (google search). They have firehose for msm 8998 but I removed the usb cable when it was flashing (didn't look like it was flashing anything) now the computer don't even recognize the phone....
getting this message "Unknown USB Device (Device Descriptor Request Failed)".

I wouldnt know for sure. But my understanding is the programmer files (firehose or sahara files) arent stored on the device. They are used by programmer interface to identify the processor as well as the storage media, possibly all harware for the device. If this were a more mainstream device the programmer files may have been available to us through a leak. Only way to fix it at this point would be to bring it to a shop, they should have access to the files one way or another.
I don't know, I don't have my razer phone any more, went and got myself a OnePlus 6t, the emmc file is still available to download from my post and still looking for people to mirror the file
