[HOWTO] ClockworkMod Recovery & TWRP - Upgrade/Downgrade (Touch/Non-Touch Recovery)

[HOWTO] ClockworkMod Recovery & TWRP - Upgrade/Downgrade (Touch/Non-Touch Recovery)
IF YOU TRASH YOUR PHONE USING THIS PROCEDURE, THEN IT IS A VERY GOOD INDICATION YOU ARE AN IDIOT AND SHOULD NOT BE FLASHING ANY ROMS NOR PARTICIPATING ON THESE FORUMS. . . . JUST SAYIN'. . . .
Please be VERY careful when using this method as you can brick your phone. Make sure you triple check the file you downloaded is the right size and placed in the right area, but most importantly that the command lines you type are exactly right. If you are not comfortable using this method, then please do not and go find a flashable version of these recoveries.
I've posted a procedure to format/'flash' your recovery while on your phone in one of the threads on here and was asked by a Forum Mod to make a quickie guide to be placed as a sticky on the dev boards so others might benefit.
Anyway, here is a very quick and easy way to change your ClockworkMod recovery with a couple of command lines.
The TWRP link is in the second post.
Now for the ClockworkMod Instructions:
1. First, go here and look up your ClockworkMod recovery that pertains to your phone: http://www.clockworkmod.com/rommanager
2. Download the .img file for your phone and save it on your computer.
3. Rename the .img file to recovery.img and save it to your internal sd card of your phone. For example: recovery-clockwork-6.0.1.4-hercules.img ------> recovery.img
4. Open up Terminal Emulator on your phone and type the following 2 commands:
su
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p22
(please note the second command is a one line command with spaces between "dd & if=" and ".img & of=")
If your Rom identifies your internal sdcard as /emmc instead of /sdcard, then make the adjustment to command line (dd if=/emmc/recovery.img) instead of what is posted above.
That simple.
You can also issue these commands from adb shell if you are connected to your computer.
If Terminal Emulator does not have Superuser or SuperSU permissions for root privileges then make sure it does. You can also go from NON Touch CWM to Touch CWM using this and vice versa. Simply make sure you have the right recovery for your phone and rename it to recovery.img.
As for explanations:
dd if= command is a common Unix program whose primary purpose is the low-level copying and conversion of raw data.
dd stands for "data description"
if stands for "input file"
of stands for "output file"
the = is the location of the data you are using. ie. /sdcard/recovery.img
the /dev/block/mmcblk0p22 is the location/partition of the recovery on your phone.
So essentially you are doing a low level rewrite of the recovery image on your phone via command lines.
***Also, the best way to remember this command line is to not to. Copy the command line and save it to your own personal contact info in Google under Notes and then you will have it with you wherever you go. You really do not want to mess with getting it wrong. You could brick your phone if you mess things up.
Anyway, I hope this helps. . . . it really is very easy to execute without fault.

Works with TWRP too.
This also works with changing to and from TWRP. Download the image (for our phones it's TWRP 2.3.1.1) rename it to recovery.img and follow the above instructions and you are good to go.
Follow this link to get the image file: http://teamw.in/project/twrp2/101
***I attached the old TWRP 2.2.2.0 is case you run into problems with the newer versions not restoring backups properly or renaming backups correctly.***

Excellent Thread, I hope Dev's requiring specific CWM versions can link to your post.
Thanks for your efforts.

Thanks for the instructions! Thanks even more for explaining the command lines.

Just thought I'd point out a small bug with the Touch Recovery. If you flash one of the newer ICS roms like Darkside Evolution through the Touch Recovery, once booted, the ROM WILL NOT SLEEP through time out. I've confirmed this with 2 separate ICS roms. Flashing non-touch recovery through Rom Manager fixes this problem.

Wouldn't it be easier to use gscript and run the commands as you need them?
Thanks for the HOW TO I actually was looking for it.

What is wrong with ROM Manager? I use it to go between Touch and normal all the time and it works flawlessly.

For some people Rom Manager doesn't work. On the T-Mobile SGH-T989 Galaxy SII, Rom Manager will only allow you to go to 5.0.2.6 not 5.0.2.7. And, I think you have to upgrade Rom Manager to go to Touch. I bought Rom Manager, and don't use Touch Recovery, so I am not sure.
I like to use the command structure verses program because I know it works, it's fast, and I can see the results if an error occurs.

Oh yeah...this was really simple...Thanks...went from Touch back to Non Touch.

Give this a try
If you want a simple way to flash the Touch Recovery then give this a try. I will be adding the Hard Recovery as well in the next release.

I get a write error: No space left on device. 1001+0 records in 1000+0 records out 512000 bytes transferred in 0.132 secs.
I reboot into recovery and it's still on 5.0.2.6
Edit: so i closed the terminal and I ran it again, and now my phone won't turn on. I get a USB device in windows called QHSUSB_DLOAD. I hold the power button, and the device disappears, but it won't turn on. I let go of the button, the same device reappears.

hate to be the dude that tells you this but i'm pretty sure qhsusb_dload is magic windows talk for "hard bricked phone." had that problem a while back. however all is not lost - these guys have a great reputation for Lazarus-ing dead phones.

Haha no worries bro. I mean worries that it failed for no reason, but I already sent it in, he just got it today. Same person you linked. Definitely trying to install ics again when i get it. Plus I think the ota ics for tmo came out yesterday or something? Probably a better experience than what was already out there with the radio and stuff.

the files from the CWM site are not .img for me, they are .ndif is it the same procedure?

No! Do NOT use this procedure with that file extension!
What recovery are you trying to install? And for what phone? I briefly ran my cursor over the various files and the download links are either .img or .zip files. I did not see .ndif file extension.
PM me if you need additional help.

Would you happen to have the .img file for 5.0.2.7??
Edit* Nvm.. a quick google search and I was able to find it. You are a life saver.. I tried updating my recovery to the 6.0.1.2 Hercules port and for a couple days, it was working great up until an hr. ago. Nothing would flash and it would just hang in recovery... so I found this thread and thankfully I was able to downgrade back down to 5.0.2.7.
If you were local, I would take you out and get you piss drunk for helping me save my device. Cheers!!!!

You're welcome, I'm glad I could help you. But, the link to the .img files is in the OP instructions. . . .

Unfortunately this method did not work for me... I have tried many ways to update my CWM and none of them worked, it is almost hopeless for me

Rooting Every Spreadtrum SC6820/SC8810 phones ! (1.5)

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:
0x1782
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 !

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

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.

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:

adb shell

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.

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.

"busybox dd if=/dev/block/mmcblk0 of=/sdcard/backup.bin bs=1M count=70"
It will create a backup.bin in the root of /sdcard. ipload that file here. if the file type isnt supported, put it in a .zip then upload it using your pc. if you dont have a pc, just rename the end part of the file (.bin) to (.zip) and upload it here.

Get your phone and turn it off. Once its off, hold vol down + home button + power button until you get the prompt to go to download mode. click vol up and it should say "Downloading...". Connect the phone to the computer, and Odin should recognise it. go to the AP slot, click it, and navigate to the file you extracted. Wait for Odin to recognise the file. After, click start, and don't disconnect it until it says "PASS" on the screen, or the phone boots up completely in the set-up. Its recommended that you eject the SD card in your phone (if you have one). Also, make sure only F reset time, and auto reboot are checked.

Just do what i told you to do earlier. read the other comments. the commands are over there

Hey man! Sorry I haven't been able to respond recently. Sent you a pm, but basically I've been in and out of town a lot the last few days!
Got a couple items that makes the process of creating a debrick.img very easy! Started out with a simple script and it evolved from there!
This one will create a 128mb debrick.img on your internal sdcard. (/sdcard/debrick.img)
Download this and flash in TWRP: https://www.androidfilehost.com/?fid=23196940996969297
That's It! Now just zip and upload!
(ignore the T999 in the filename
It will work on the I747 too)
This next one is slightly more difficult to use, but still easy if you just follow the instructions included in the zip file.
It includes options to create 128mb, 256mb and 512mb images. You should only need the 128mb one but we were using this for testing and troubleshooting when new firmwares were released.
Do NOT flash in recovery. Unzip and follow the included instructions. It will create the debrick.img and then will zip it for you using 7zip.
https://www.androidfilehost.com/?fid=23196940996969297
The first is the easiest and probably all you need. Just included the second in case anyone wants to try it or the first method doesn't produce a working image. (Doesn't fix a brick)
Hope it helps!

Here goes nothing...

Explain like I'm a three year old, I beg of you.

I politely ask any person able to help to explain to me, like I am a three year old, exactly how to update a Samsung Glide from 4.0.4 to whatever newer version is able to work on the phone, that is rooted? AGAIN... I ask this politely.

No problem, we are all new at this once, right?
First Step: Downloads!
TWRP:
http://dualhoki.vim.hu/bubor/dev/twrp-i927/twrp-2.8.4-for_odin.tar.md5
ROM:
Here is a matter of preference. If you want the latest *working* version, you can upgrade to 5.0, but you lose the camera. I presume you want the camera to work, so I suggest Bubor's CM11 for KitKat. There are other good roms too, like PAC and SediRom, but we will start with Bubor's CM11.
http://dualhoki.vim.hu/bubor/dev/11.0/cm-11-20160126-UNOFFICIAL-i927.zip
http://dualhoki.vim.hu/bubor/dev/11.0/cm-11-20160126-UNOFFICIAL-i927.zip.md5sum
ODIN:
http://www.mediafire.com/download/7us5q44aab1xl9d/Odin304.zip
Second Step: Prepare.
I am presuming that you are using a Windows computer. If you are using a Linux computer, I can tell you what to do also, but these instructions are for Windows. I am also presuming that you have an external SD card in your phone, if you do not, go buy one and put it in your phone.
Unzip the Odin304.zip by right clicking on it and say unzip/extract, etc. If your Windows does not have this option, you need to download a program like winzip or 7zip so you can unzip this file. If you need those programs, they can be googled and downloaded.
Third step: Further preparation.
Turn on your phone and plug it into a usb cord and plug the usb cord into your computer. If you are using Windows, it will try to find drivers for the phone. It should be automatic and just work. If it does not, then you need the drivers, which are here:
http://www.mediafire.com/download/0up21ccc9gajwjv/Samsung_USB_Driver_for_Mobile_Phones_v1.5.14.0.exe
*If you downloaded this file, just double click it like a program, it should open and install drivers for your phone. Do not do this unless your computer cannot find drivers for your phone!
Fourth step: Charge your phone.
Plug in your phone and FULLY charge it. ALL the way to 100% CHARGED. No exceptions. No shortcuts. Do it. Then UNPLUG YOUR PHONE AND TURN IT OFF.
Fifth step: Put TWRP on your phone.
a. Your phone should now be unplugged and off. Open the ODIN folder that you unzipped earlier and double click on ODIN to open the program.
b. Click on the PDA button ( you and I both know that your phone is not a PDA, this is not a typo ) and it will open a browser. Find the twrp-2.8.4-for_odin.tar.md5 file and select it. It should now fill in the blank line next to PDA with this info.
c. WHILE HOLDING THE UP VOLUME BUTTON ON YOUR PHONE, press and hold the power button. When you see "SAMSUNG" you can release the power button, but KEEP HOLDING THE UP BUTTON, untill you see a yellow triangle and warning notice. If you hold too long, that is okay as it will take you straight to the download mode with the green android that says "ODIN" at the top and "Downloading" in the middle. If you got stopped at the yellow warning/triangle, press up again to go to download mode.
d. Plug your phone into the usb, and the usb into your computer.
e. In the Odin program, press start.
You should now see a serries of verbage going by on the left, at the top a green bar may fill in, and hopefully, in the end it says "success" or "pass". Your phone should reboot all by itself. If ODIN says fail, ask for further instructions. If passed, close Odin.
Sixth step: Put your CM11 files on your phone.
Your phone should have rebooted and looks just like it did before, now powered on, and in your stock Ice Cream Sandwich firmware. As with any file transfer, plug your USB into the phone and computer. Drag the CM11 files to the phone. Anywhere will do, but if you have an external SD card in your phone, I recommend you put it there.
Seventh Step: Boot into TWRP.
a. Turn off your phone.
b. Unplug the USB.
c. HOLD THE DOWN VOLUME BUTTON and press the POWER BUTTON. When you see "Samsung" release the POWER BUTTON, but keep holding the VOLUME DOWN BUTTON. At the top of the screen, white letters should say something like "entering recovery".
d. When you see "Team Win Recovery Project" release the down volume button.
Eighth step: Make a backup!
a. Press "Backup" button on screen.
b. Check all checkboxes (system, cache, data, boot, Android Secure)
c. Press "Storage: sdcard (xxxx mb)" bar.
d. Select "External_sd" to choose to backup to your external sd card.
e. Slide the swipe bar to the right to backup. This will take a few minutes, with progress bar.
NOTE: if the screen dims, when you touch it, you will see a TWRP lock icon, swipe right to unlock it.
f. When backup is completed, it will say "reboot system", do not click that. Click the "home" icon in the lower left corner.
g. Click the "Wipe" button.
h. Swipe right to factory reset.
i. Click the "home" icon in the lower left corner.
j. Click the "install" button.
k. At the top, click on the "Storage: sdcard (xxxx mb)" bar.
l. Select "External_sd"
m. choose the cm-11-20160126-UNOFFICIAL-i927.zip
n. When that is done, click on the "reboot system" button.
The system will reboot. You should now see CM11's boot screen. The first boot takes a bit of time.
Ninth step: Thank Bubor.
a. Log into XDA.
b. Go to http://forum.xda-developers.com/captivate-glide/development/dev-cm-11-0-t2802184
c. Slap every thanks button that is for a post by Bubor untill it tells you that you cannot slap any more thanks buttons (that is only 8 thanks per day).
Tenth step: Enjoy your phone!
....I think you know how to do that.....
If you have ANY questions, please just post them here and we will see if we can answer them.

I am thanking you so very much! Also... I do apologize for such a time lapse in my reply. Life happened.

I followed the above procedure and have CM11 installed. But my problem is I can't use my SIM card anymore because it's like my phone doesn't see it at all. I checked my settings and saw that I no longer had an IMEI number. I used the restore feature and the stock ROM had an IMEI number. What should I do? I saw a few threads about using a program to rewrite the IMEI or others to copy the file containing the IMEI but I wasn't really sure what I should do or how to copy files to and from that partition from my computer. I should add that the phone is unlocked.

Great question, and an interesting problem!
First, I am really glad that you followed the instructions and made a backup! It is good to know that you can always go back to the way it was.
I recommend that you download another rom from the developer section here, such as Sedi-rom, omni-rom, etc., and try flashing that. If you flash one of those roms, does your IMEI stay for those roms?
Try this one: http://forum.xda-developers.com/showthread.php?t=2789727
You can do steps 7 through 10 with any of the roms in the developer thread. If this other rom works, you can use it, or download others and try them. If the SediRom does not work also, then we will need to sit down and figure this out.

I really appreciate the fact that you're here to help.
I downloaded and installed SediRom 2.1.2 and my IMEI still shows as "Unknown." However this time I should add there is a serial number, which I don't believe was present in CM11 or in the stock ROM, although I'm not sure if that's at all significant. I made an external backup of the efs file from the stock ROM, is there some way I could just reinstall CM11 and replace/overwrite the efs to give it an IMEI number? I'd really like to use CM11 if possible, I was enamored by how good it looked and how functional it was, especially since the last time I tried CM a long time ago I didn't have such a good opinion of it. Plus the bootloader is friggin sweet !
I recently got the phone unlocked off eBay, so I don't know its past history but I was able to access the network when I had the SIM card in prior to initially installing CM11 but not afterwards. I'm trying to use a T-Mobile SIM but like I said I was able to successfully access the network prior to installing CM11. But the IMEI doesn't show at all regardless if the SIM is in at all.
Is there some kind of different hardware/firmware like in a newer slightly different version of the phone that came out resulting in compatibility issues? I'm not the most experienced but I've dipped by toes in this before, so I would be willing to go the extra mile if it meant I could get CM11 to work, because honestly it looked like everything I could ever want from this phone with a good looking theme too...

Do you have a full backup of the efs partition?
If so it should be enough to restore it.

Yes I believe so. I used the procedure from this thread to back it up. I tried copying the efs directly over using the built in file manager with root access, but when I try to copy the entire efs folder over I get a non-descriptive error "this operation has failed." I tried copying the nv_data.bin folder by itself to overwrite the one currently there (which copied successfully), then rebooted the phone but the IMEI still shows as "unknown." Do I need to copy the efs while the phone is in recovery mode or via PC or something because of file in-use errors or something else I don't know about?

Well restoring efs have to be done in recovery only! Do not try to do this while android is running!!
To be honest the absolute best way is having a dd partition dump of the whole partition. When you have followed the mentioned guide do you have used also dd like this?
dd if=/dev/block/mmcblk0p1 of=/storage/external_SD/efs.img
I don't know if copying the efs folder alone would work.. better is restoring the whole partition if possible. Do you have such kind of backup?

All the best!

So I'm really late here but the phone got thrown to the backburner and I forgot about it. Lol but anyways, I created the EFS backups using dd like it said, but I'm not sure how to restore them? Do I unpack them and then use ADB to move them there? I'm kind of confused. Also, for some reason going through the TWRP to the stock ROM doesn't let me root it, it crashes every time I get to that screen, don't know if that's important to the operation. Hope I can finally get this stupid thing working right with the custom ROM...

Okay so I used TWRP to do a factory restore, flashed SuperUser, then flashed CM11, went into TWRP and did the terminal commands you listed in the guide for backing up the EFS... to no avail. Would it be better to copy the EFS while I'm still on the rooted stock ROM using a terminal app? I don't understand what the problem is...

DId i Brick my Samsung Galaxy A505FN?
Hello one Question:
"did i Brick my device if for some reason after Trying to flash TWRP it fell back in to OEM-locked and i’ am now in a Boot Loop, ore is the any Hope?
I used Heimdal and at first it did the Job but then it would not start again as expected.
After some attempts to flash it Properly it suddenly fell back in to OEM-Locked!
Pleas if you now some advice it be greatly aprichiatet
My device is a Samsung Galaxy A505FN (Spain)

I found a way to Unbrick my device
Just to let anyone that pass her know i finally found a way to unbrick my device here it is:

All i know in case of my Samsung Galaxy A50 it is Possible!
To lift the OEM-Lock mode again.
i do not know if that is true for every Device.
Ultimately i was successful to install full Root-access!
I had great difficulty tho to use Heimdall ore any tool on Linux so i ended up using Odin in a VirtuelBox with WinXPpro
but do to no support of Long file names i had to trick there, to to make it work.
I just shorten the Names of every .tar to the first 2 letters.
I was able to successfully flash TWRP with Heimdall but not the Android ROM for my Phone.
I still wonder how to make it work!
There was one Thing i Noticed when Using Odin it seams in the Process he flashes vbmeta.img twice.
That impossible with Heimdall it creates a error message.
Well if anyone - that passes here - knows how to flash a Android 10 ROM of a Samsung Galaxy A50 using Heimdall let me know i tried very very hard to no avail.
I was surprised to learn there is no Good Tool for Linux-user doing this Task.
i only found Old Tutorials!
Is it truly possible that Heimdall dose not support modern Phone-flashing anymore properly?
As of now if a Linux-user ask me about Rooting i would advice him/her to do it in a VritualBox with windows installed.
If you have a License of a Windows Version Higher then XP good otherwise you have to Shorten File names if the very long to make it work.
I scarcely use windows anymore that why i only have a old WinXPpro legally in my Possession.
Unbelievable that the Linux-Community should not have a modern Flash Tool!???

---------- Post added at 12:38 PM ---------- Previous post was at 12:18 PM ----------
Hello to @everyone
I had great difficulty to do this as a Linux User using Heimdall and eventually had to give up (after trying for 3 full days)!
I ended up doing it using Windows out of a VirtualBox!
It was Possible tho to successfully flash TWRP using Heimdall!
It also showed Success when Flashing Android 10 Version for my Phone but would not work.
Using the same Firmware with Odin it worked just fine.
When i compared the Flash-Protocol of Odin with what i did i only Noticed that Odin would flash vbmeta.img twice in the Process something that cant be done with Heimdall as it produces the duplicate error.
I wonder if this is the Reason it would not work.
I was also surprised to Learn, that there is virtual now Tutorial out there using Heimdall on a Modern Phone (last 12 Month ore less).
Is it truly Possible that There is now good solution for Linux Users?
I also Looked in to Fastboot and ADB and other Tools for Linux Platform and they all seam to be outdated!
Also all this Tools could not accomplish the task at hand.
Now if its me and anyone knows how to make it Work on Heimdall let me know as it is a Pretty good tool after all and by now i know it well. I would gladly start to make a tutorial and provide it here for free if i know how to make it work.
I have a txt file where i made a complete Protocol of all i tried if someone is curious ill send it to you.
Saludos Hans
##################################################################
I send some more Details of my Challenge in hope someone my know what it is i have to change!
My Device:
Samsung Galaxy A505FN
I created a .txt file protocol of all i did, i gladly provide it if someone ants to see it.
I analyzed the Whole Firmware-archive and the Pit file of my Phone to eventually find the Problem.
Note:
The Firmware was the correct one as it worked just fine using Odin!!
Analyzing all this, i only noticed two things:
First:
There are 3 seemingly identical files in the Archive and two so called
fota.zip files witch are not Identical
(one in the AP-Packet and one in the CSC-Packet)
Those where:
– cache.img one in the AP-Packet and one in the BL-Packet
– vbmeta.img one in the AP-Packet and one in the BL-Packet
– product.img one in the AP-Packet and one in the BL-Packet
Second:
Once i used Odin to finally flash successfully i noticed that in the Flash-protocol of Odin it seams Odin flashes the vbmeta.img twice in the process!?
Heimdall would not allow me to do so giving me the “Duplicate Error message”
Furthermore i tried one more thing in my desperation to make it work:
i thort: “maybe the order in wish the files a flashed chronologically matters”
So i did exactly that, trying to flash in the same chronological sequence as Odin did.
Note:
Every time i flashed, Heimdall would successfully finish the process but the Phone would not start with android
no matter what i tried.
ALSO i did successfully flash TWRP to my Phone using Heimdall
SO Heimdall works just fine on my system!
I spend a Long Time searching the Internet for a workable Tutorial or glue’s as to what is missing and how i could make it work.
I really want to succeed doing this, as i want to provide my folks offer her in Germany and also English and Spanish speaking Linux-Community with a Tutorial to do this!
I did also drop this Question and Challenge i face in some other Forums no useful answer returned so far
The latest Governmental Abuses and infringement on Peoples Privacy using Corona as excuse, makes it abundantly clear how important this kind a work is!
As for now i think, the only true option for a Linux-User is to run Odin from a Virtual-Box Windows installation, given
you have a legal copy in you're possession and have higher then Windows XP
(else you must change the Filenames of the .tar archives as WIndows XP and lower did not support excessively long filenames.)
Also you have to Install you're Phone USB drivers and have them up and running properly!
Internet access to you're VB makes it all more comfortable, but you can also use Shared folders with the Host-System to do the job.
Note:
I did indeed tried the "WINE-plugin-environment" (Windows 10) under Linux. i could not get it to work.
It was to much messing around make it recognize the USB-connection to the Phone!
I could not get it to work, I don't know if you can?
I guess that would be a nice way for Linux-users if it could be made to work!
What do you guys think, can this be solved?
Pleas let me know if you know the answer to my Challenge!
You're help is not only needed but would be greatly appreciated
Sincerely yours
Hans from Germany

well I Found this from 2017;
Yes you can do fastboot and adb cmd in Linux but you have to install adb and fastboot drivers to Linux by using
1) sudo add-apt-repository ppahablet-team/tools && sudo apt-get update
2) sudo apt-get install android-tools-adb android-tools-fastboot
That's it you get your fastboot and adb cmd’s all the cmds are same just as windows just you need to add sudo in front if not in root

so maybe have a read of this too; https://android.gadgethacks.com/how...actory-images-android-using-fastboot-0175277/

Well i do know
Of course i know how to Install a Software on Linux and i did indeed installed those Two
But both of them would not even Detect my device jet Heimdall and Odin had no problem doing that.
Anyhow i might go about and try those Two harder.
And no Iam not confused
thank you anyway

USB File Transfer Does Not Work
After flashing the ROM, when I connect my phone to my PC with the USB cable to transfer files, it does not work. No errors on my PC. I tries switching between modes and back to File Transfer as some suggested, but no luck.
Has anyone experienced this and if so, any solution?

This is what you get with a GSI, finger print wont work either.

Actually it's the only Custom ROM where the finger print works. My only problem was with the USB File Transfer.

Try with a custom kernel

the project is down? Because I love LineageOs, but the A50 is abandoned :/
