[TUTORIAL]How to setup SP_Flash_Tool_Linux (MTK/MediaTek Soc)

This works only on Linux 64-bit
DISCLAIMER: It is always risky to flash your mobile device. I do not and will not take any responsibility for bootloops and bricks.
Please check carefully that the ROM or recovery.img you want to flash is suitable for your specific device and for the sp_flash_tool. The firmware directory should neither contain meta-inf nor system folder, but something_with_a_scatter.txt and a system.img
Backup your phone before flashing!
Your phone's battery should be at least half charged (50 percent) before you start this.
I successfully ran these steps on my UMI Hammer with Linux Ubuntu 14.04 and 16.04. I do not have other devices or Linux derivates and do not plan to buy/install any.
CREDITS and a zillion thanks to Sergio Rivero for his excellent tutorial on mibqyyo.com!!!!
Also many thanks to N2K1 for giving me some more background information!
So here we go:
Step 1:
If you haven't done so before, install the Linux generic usb-drivers package:
Code:
sudo apt-get update
sudo apt install libusb-dev
Download SP Flash Tool Linux (latest version): http://mtk2000.ucoz.ru/load/soft/soft_mtk/sp_flash_tool/5-1-0-14 (Password to extract currently is mtk2000v3)
or here https://androidmtk.com/smart-phone-flash-tool
In case you haven't done before, install unrar:
Code:
sudo apt install unrar
Extract the downloaded file -> graphic file manager (e.g. Nautilus): double-click and extract. Terminal:
Code:
unrar x path_to_file
(from now on: please adapt paths to your own settings)
Move the new folder „sp_flash_tool“ to a directory of your choice.
Code:
mv /home/username/Downloads/sp_flash_tool /home/username/...
You might also need to install libqtwebkit4 (it just happened to me on Linux Ubuntu 16.04):
Code:
sudo apt install libqtwebkit4
[Only For Ubuntu 16.10 and newer]
Run
Code:
dpkg -x libpng12-0_1.2.54-1ubuntu1.1_amd64.deb /tmp/libpng2
cp /tmp/libpng2/lib/x86_64-linux-gnu/libpng12.so.0.54.0 lib
cd lib
ln -s libpng12.so.0.54.0 libpng12.so.0
These libraries are still required for the flash tool but have been removed from new Ubuntu versions.
Thanks @hanalinqu, @z3r0c00l_2k https://forum.xda-developers.com/showpost.php?p=73484473&postcount=216 and @opticyclic https://forum.xda-developers.com/showpost.php?p=81543495&postcount=285 for this information!
Step 2:
Change into the newly created directory:
Code:
cd /sp_flash_tool
We make one file executable by typing:
Code:
chmod +x flash_tool
In order to avoid running the flash_tool as root user, you need to add a standard user to the usergroup "dialout" (thanks to @egalus for this bit!)
Code:
sudo adduser username dialout
For Arch Linux:
Code:
gpasswd -a username uucp
and activate the membership immediately
Code:
newgrp - dialout
(Arch Linux):
Code:
newgrp - uucp
Step 3:
Now you can open the tool:
Code:
./flash_tool
or double-click on the flash_tool icon.
You can try at this stage if the flash tool connects to your phone:
In the user interface, choose tab „Download“. Hit "scatter-loading", navigate to a directory with a valid firmware for your device and choose the scatter-file.
For testing purposes uncheck "name" and check one of the smaller files in the list below (for example "logo")
Switch off your device. Hit the "Download" button in SP_Flash_Tool and connect your phone to the computer. Some devices require you to take off the battery for about 10 seconds, with others you need to press Vol+ or Vol- while plugging the cable into the phone. Please look up device-specific threads and try out different options.
If nothing happens at all, open a second terminal, run
Code:
dmesg | grep usb
and look out for a MediaTek entry. If there is none → did you install libusb-dev (Step 1?)
If the answer is yes, you might need to create a persistent udev rule for the MTK Preloader:
Code:
sudo gedit /etc/udev/rules.d/80-persistent-usb.rules
Add the following line to the file:
Code:
SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="0e8d", ATTR{idProduct}=="*"
Save the file and exit.
Reload the usb-rules:
Code:
sudo service udev restart
Disconnect the usb data cable from the computer and the smartphone. Close the flash tool. Switch on your phone (fastboot mode will do). Repeat the first paragraph of Step 3.
If the tool connects, within a few seconds a red progress bar will appear. Unfortunately, in my case an error message came along with it:
S_BROM_CMD_JUMP_DA_FAIL (2035)
There is a connection, but also one more obstacle to overcome...
Step 4:
Now we come to the interesting part, which cost me 2 weeks of (futile) research and frustration. Finally I found Sergio Riveros tutorial on mibqyyo. Thanks to him again and again and again for this priceless piece of information
The “modemmanager” package integrated by default within Linux Ubuntu 14.04 and later is not compatible with the MTK Flash Tool for Linux
Click to expand...
Click to collapse
To put it in different words: The modem manager controls port /dev/ttyACM0 and disables the Flash Tool. So we blacklist it for the two MTK vendor IDs the flash tool uses:
Code:
sudo gedit /etc/udev/rules.d/20-mm-blacklist-mtk.rules
You insert these two lines:
Code:
ATTRS{idVendor}=="0e8d", ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="6000", ENV{ID_MM_DEVICE_IGNORE}="1"
Save the file, exit and restart udev:
Code:
sudo service udev restart
Switch your phone on (fastboot mode will suffice) and off again.
Step 5:
Code:
./flash_tool
or double-click on the flash_tool icon.
Now everything should run smoothly. In case you encounter
Code:
BROM ERROR : S_SECURITY_SF_CODE_FORMAT_FORBIDDEN (6012) , MSP ERROE CODE : 0x00
change the download agent to MTK_AllInOne_DA.bin (screenshot #4)
There are plenty of tutorials on the web for the further steps.
Happy flashing! When a green circle with a white checkmark appears, you are done. You can close the flash tool and disconnect your phone. For a clean start with a new ROM boot into recovery and wipe data/factory reset.

Kudos for the udev rules, I finally managed to root my phone and disable some vendor crap thanks to you!

Thanks, I'm glad to read that it worked for you as well

Great post!
Just wanted to say you saved me HOURS OR DAYS OR WEEKS of time on the modemmanager thing. I have Arch Linux, successfully ported over this tutorial, but I had no idea the modemmanager package was causing the issue. SP Flash Tool was the last frontier for using my Android devices on Linux. Thanks so much!

You are very welcome! Since it took me two weeks to find the cause for "S_BROM_Error [2035]" I wanted to spare other "victims" the experience

This is a very nice, HQ post. Keep up the good work.
But I would like to suggest two corrections:
1) The mv command is unnecessary. you don't have to copy the folder to the root directory to run it as root.
2) Please also add a final step to delete the udev rules so as to re-enable the modem manager after rooting.
Though most of the people who would be reading your thread would be knowledgeable linux users, they won't need these suggestions, but anyways, it would make your guide complete.

Thanks for your feedback @daltonfury42
1) Of course you don't need to move to move the folder to / .As I wrote, you can also use your /home/user directory. But you shouldn't keep it in "/Downloads" or "/tmp", since you might have deleted the folder by the next time you want to use the flash-tool.
Step 2), as you suggest it, is redundant on a private computer, because you blacklist the modemmanager for the flash-tool only, and for nothing else. SP_Flash_Tool uses different Vendor and Product IDs than MTP/USB/ADB/Fastboot mode, and these IDs are not related to your specific device. So the modem manager is up and running - even while you flash - on every other active (network-relevant) usb-port of your computer And it will be up and running on the usb-port you use for the flash-tool when you disconnect the phone and then plug in something else - or the same phone in a different mode... But due to the permanent
Code:
/etc/udev/rules.d/20-mm-blacklist-mtk.rules
entry the modem manager will be automatically blocked if you connect your phone to the SP_Flash_Tool a second time - no matter which port: no further preparations necessary
If you want to check it out, take a look the output of
Code:
dmesg | grep usb
connecting your phone "normally" and compare it with the same command -> output connecting your phone to the SP_Flash_Tool - and/or to the contents of the file "usb_setting.xml" in the SP_Flash_Tool directory My udev rule simply tells the modem manager to ignore two vendor IDs named in that file.
edit: if you "flash" your linux computer more often than your Android device, you should remember to backup the folder and the udev rules

@Miss Montage, very informative. Thankyou.

You're welcome - but please do not post full quotes

Hi. Thanks for the tutorial :good:
I'm getting "PMT changed" error with the right scatter when tried to flash bootimg/recovery only.

Where did you get the scatter file? Generally this error code means that the partition table is different to the one on your device. This should only be the case - occasionally - if you flash a complete firmware.
(Or replace Android through Ubuntu / vc. vs.)

I know this error, so I am surprised
scatter is from my stock rom. Same i used to flash.

Hmm, dunno why that is. Can you compare the scatter.txt to the /proc/emmc file on your phone?
And at what stage do you get the error? Immediately after connecting or later?

The version v5.1504.00.100 works on my 64-bit-system, too... But the error seems to be caused by something else. Have you checked the SP logfile?

Have you also tried the newest version? I just involuntarily re-flashed my UMI Hammer with it... Wanted to choose the twrp only, but too much multi-tasking leads to no good

Working method to root the LG G4S (Model H735 / "LG G4 Beat")

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.

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:

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

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.

[ROOT]G955U/G955U1 SnapDragon SamPWND Root IS HERE!

FINALLY!
We Present To You
SamPWND!
Root for the USA Variants of the S8 & S8 Plus Devices!
(This thread will focus only on the S8+)
This thread had been closed/locked until further notice. The thread and links should remain active and the thread has served it's purpose. You will need to search the thread if you have any questions pertaining to root or any errors/issues that you are facing. The other reason I have decided to close the thread is because it has gone off topic one too many times, people like to argue and debate and MODS have had to come in here 1 too many times to clean it up so as to make life easier, I will just shut it down. Please do not bombard me with PM's for root assistance because if it has been answered in this thread already (and it most likely has) I will just direct you to search in the thread if I am able to respond at all.
ALSO, please do not utilize our firmware/root files/method without gaining permission first or I will ask for the thread to be removed/locked. Just because the thread gets closed does not mean we didn't spend a lot of time to get to this point.
Thank you and enjoy SamPWND root!​
DISCLAIMER:
We are not responsible for any damage done to your device as no one is "forcing" you to root your phone! If you are not sure of how to follow instructions or use ADB then I would suggest waiting for someone to help you or that you read up on how these things work before diving head first. The ENG system is not very stable when it comes to root as well as it has a ton of tools and binaries not available on stock devices so we are not responsible if you break something while on any firmwares but especially while on the ENG firmware.
DISCLAIMER 2:
Please do not take our work and post it elsewhere. We spent a lot of time on this for people to take it and use it as if it is their own. With that being said, if you have a better process for something or find any issues/errors, please PM myself or one of the listed contributors of this root method, do NOT post it directly in the thread because it causes confusion. We know with 100% certainty the files and method presented WORK. If it is not working for someone there are a number of possible reasons why. If users start modifying our files/scripts and posting them and you decide you are going to use someone else's files/scripts, do not post in our threads asking for us to help you because we will have no idea what was modified or changed and will just tell you to use the original files.
Returning to Stock:
- It is possible to return to 100% stock and it is very EASY to do.
- This is the reason why I provide both Normal, and Comsey ODIN's.
- All you need is a full stock 4 files firmware of your choice.
- Extract those files. Open ODIN and select the 4 files in their respective slots.
* IF YOU GET ERRORS such as model mismatch, start with 1 partition at a time to find out which one is throwing the error. (In my experience, it is the BL file that causes the error.) Once you find the culprit, throw that partition into the other ODIN. (For example, the BL file is giving an error in Comsey ODIN, throw the BL file in NORMAL ODIN and flash it by itself.)
* Typically you might have to throw individual partitions into either of the ODIN's but in the end you will be back on full stock firmware.
What doesn't work while rooted?
- On ANY ROOTED device, anything that utilizes "SafetyNet" will NOT work.
- Magisk and/or SuHide will NOT work. Our bootloader is still locked and these two modify the boot.img which would cause our devices to not boot up and having to start the root process over again, you have been warned!
- Systemless root also does NOT work. Again, this patched the boot.img which we cannot do because of our locked bootloader.
- Battery currently only charges to 80%. There are a few that feel it legit doesn't charge fully but others are claiming they get the same amount of life as they did with a 100% battery so the 80% might just be a visual issue or "fake" when it is really at 100%. Either way, we are still looking into this.

@jrkruse (for uploading system.img.ext4 and his root zip for the part 2 instructions)
@V0idst4r (for help in creating a "1 click" method for part 1!)
Initial Description on the process:
We are essentially flashing a modified 4 file firmware package in ODIN and then utilizing a few binaries in conjunction with SU binary and a permissive kernel. We will then be running some ADB commands and in order to have a fully working, amazing root with all things working we will be utilizing a stock system.img & a root script in conjunction with Flashfire. If you want to know all the technical details, you can take apart the files if you would like. It is released, so it is no longer a secret!
PART 1 Instructions: NEW
Flashing SamPWND 4 Files Firmware:
1) Download the PART 1 FILES Listed Below (this includes SamPWND_Root.zip and Initial ODIN 4 Files FIRMWARE and ODIN's if you do not already have them.)
2) Extract the 4 Files ODIN Firmware Package (also extract the ODIN's if you do not have them already.)
3) Open Comsey ODIN and select each partition and then select the files from the 4 File Firmware Package you extracted (BL goes in BL slot, AP in AP, CP in CP & CSC in CSC.) The options you select in ODIN shouldn't matter but I typically select F. Reset Time, Auto Reboot, Re-Partition, Nand Erase All & Update Bootloader.
4) Press Start and Wait for it to Finish. Once it finishes, if it boots into stock recovery simply select "Reboot System"
Take a breather, the ODIN portion is done (unless you have to start over for some reason...)
Now the NEW Root Process:
1) Once the phone is booted up, make sure you have ADB Enabled and connected to your PC. It should have prompted you to accept USB debugging as soon as it booted up.
2) Unzip the SamPWND_Root.zip
3) Double click "step1"
4) Wait for it to finish and once it reboots and comes back on you will be rooted with SuperSU!
5) Continue to PART 2 for "EVEN BETTER ROOT"
* It is a Windows bat file so not sure if it works on MAC. If you can't run bat files, use the OLD instructions.
* The bat will take about 30 seconds to run it's course. This is due to giving enough time for the remount script to mount the system as RW.
PART 1 Instructions: OLD
1) Download the PART 1 FILES Listed Below (this includes Systemroot + ADB zip, Initial ODIN 4 Files FIRMWARE and ODIN's if you do not already have them)
2) Extract the 4 Files ODIN Firmware Package, Also extract the ODIN's if you don't have them already.
3) Open Comsey ODIN and select each partition and then select the files from the 4 File Firmware Package you extracted (BL goes in BL slot, AP in AP, CP in CP & CSC in CSC.) The options you select in ODIN shouldn't matter but I typically select F. Reset Time, Auto Reboot, Re-Partition, Nand Erase All & Update Bootloader.
4) Press Start and Wait for it to Finish. Once it finishes, if it boots into stock recovery simply select "Reboot System"
Take a breather, the ODIN portion is done (unless you have to start over for some reason...)
Now the ADB Process to actually Root:
1) Extract the Systemroot + ADB zip listed below in an easy to find directory.
2) Make sure phone is connected to PC and ensure USB Debugging is enabled.
3) In the folder you extracted, you should see a "cmd-here" file. Double click it and it should open up an ADB cmd window.
4) Now we will start with the ADB commands:
- Type
Code:
adb push systemroot /data/local/tmp
What it will look like:
C:\Users\Thomas\Desktop\Minimal ADB and Fastboot>adb push systemroot /data/local/tmp
/data/local/tmp/systemroot/: 8 files pushed. 0 files skipped. 10.0 MB/s (7072263 bytes in 0.673s)
- Type
Code:
adb shell chmod -R 7777 /data/local/tmp
What it will look like:
C:\Users\Thomas\Desktop\Minimal ADB and Fastboot>adb shell chmod -R 7777 /data/local/tmp
C:\Users\Thomas\Desktop\Minimal ADB and Fastboot>
- Type
Code:
adb shell setsid su
What it will look like:
C:\Users\Thomas\Desktop\Minimal ADB and Fastboot>adb shell setsid su
(It will be blank with the blinking cursor, move to next step)
- Type
Code:
id
(you should at this point see that your are in a root shell!)
What it will look like:
id
uid=0(root) gid=0(root) groups=0(root),1004(input),1007(log),1011(adb),1015(sdcard_rw),1028(sdcard_r),3001(net_bt_admin),3002(net_bt),3003(inet),3006(net_bw_stats),3009(readproc) context=u:r:shell:s0
- Type
Code:
echo /data/local/tmp/systemroot/remount2.sh > /sys/kernel/uevent_helper
What it will look like:
echo /data/local/tmp/systemroot/remount2.sh > /sys/kernel/uevent_helper
(Again, it will be blank with a blinking cursor after you type the command in, move to next step)
- WAIT ABOUT 30 SECONDS BEFORE MOVING TO THE NEXT COMMAND
- Type "
Code:
mount
" (you should now see rw next to rootfs and system partitions)
What it will look like:
mount
(After we type in mount, we are looking for the below two items to say rw like they do in the next two lines)
rootfs on / type rootfs (rw,seclabel,size=1586716k,nr_inodes=396679)
/dev/block/sda19 on /system type ext4 (rw,seclabel,relatime)
- Type
Code:
sh /data/local/tmp/systemroot/root.sh
What it will look like:
sh /data/local/tmp/systemroot/root.sh
rm: /system/bin/install-recovery.sh: No such file or directory
cp: /system/bin/.ext/.su: No such file or directory
chmod: /system/bin/.ext/.su: No such file or directory
chcon: /system/bin/.ext/.su: No such file or directory
touch: '/data/.supersu': Permission denied
/data/local/tmp/systemroot/root.sh[55]: can't create /data/.supersu: Permission denied
chmod: /data/.supersu: No such file or directory
C:\Users\Thomas\Desktop\Minimal ADB and Fastboot\NEWSAMPWNDFILES>
5) If you followed all of the above commands to the T, your device will reboot and you will have SuperSU installed.
6) Install Flashfire from the Play Store.
7) Up to this point, you are on an ENG system.img with root that doesn't function the way we would like it to. This means you will feel a vibrate every time you try to gain SU access as well as it will take quite a while for an SU prompt. You can stay on this root if you would like to experiment with the ENG system, but outside of that I would HIGHLY recommend you proceed to the STEP 2 PROCESS.
PART 2 Instructions:
1) Download the PART 2 FILES listed below (this includes the system.img.ext4 and the add CSC Systemroot zip both provided courtesy of @jrkruse , view post #195 for specifics on what these are but essentially they are stock QD2 system.img and the zip has multi CSC, root, and a bunch of other goodies!)
2) Extract the System.img.ext4 zip and place that actual "system.img.ext4" onto the Internal SD Card (might work from external but some users have reported issues with chainfires root.zip and FF with external sd cards, this is not a fault of the SamPWND files/process.)
3) Place the entire Add CSC Systemroot zip onto Internal or Externdal SD Card (THIS FILE DOES NOT NEED TO BE UNZIPPED, THROW THE WHOLE ZIP FILE ONTO SD CARD OR INTERNAL)
4) Open Flashfire and grant it root when it prompts you. IF FLASHFIRE IS NOT LOADING FILES AND YOU JUST SEE A CIRCLE OR LIKE ITS CONSTANTLY LOADING, PUT THE PHONE IN AIRPLANE MODE AND THEN GO BACK INTO FLASHFIRE AND THE FILES SHOULD NOW APPEAR.
5) Press the + sign and select "Flash Firmware Package" & navigate to where you placed the system.img.ext4 and select it
6) Press the + sign and select "Flash ZIP or OTA" & navigate to where you placed the Add CSC Systemroot zip and select it, select Mount System as r/w
7) Press the + sign and select "Wipe" and select System data, 3rd party apps, Dalvik cache, Cache partiton, Cache Partiton format
8) Now, long press on "Wipe" and make sure it is on the top by dragging it. The order should be Wipe, Flash Firmware Package & finally Flash ZIP or OTA
9) Make sure the "Everoot" is disabled!
10) Flash away!
If you followed all of PART 1, then followed all of PART 2, then you will be updated to QD2, rooted with busybox (and have some other goodies) and the phone will be running great! Root will be stable and snappy as ever. Adaway, Root Checker, V4A etc. etc. are now all possible.

haha but we know it wouldnt be possible without you man

Dam it, if I wasnt drunk, and tired, I eould vet myself out of bed and do this now, lol. Thanks for all your hard work.
One thing i would suggest would be to either put the commands that need to be typed in as bold face type or im not sure if its possible on here, as im on my phone atm, but there are Code/code tags avaiable that will make them easier to copy and paste.
Again, thanks for this......I did not think it was going to be possible. This will be my morning present when i wake up, feels like Xmas.......

You are forgiven, lol. I figured it would be out in the morning, just not this early in the morning.
You guys should have gotten some sleep you may need it after this weekend.

What a nice thing to wake up to when I'm getting ready to head to work at 530 in the morning lol. Can't wait to give this a shot once I get off work 12 hours later. Thanks for everything devs.

S8 thread will be posted tomorrow, too late to do it tonight

You guys are the ****. Thanks for all of your hard work.

Just want to know if Knox will be triggered or not? Please also add this to the first post [emoji397]

Where's the best place to get the stock firmware we might need just in case? As far as best download speed etc.

Wow,. I honestly didn't think it was possible. Amazing accomplishment ellwigy.

Also do we need to back up our EFS/Imei stuff? I know its recommended when flashing roms in recovery but our bootloader is locked.... Is there a way to back up without root?
Edit* I asked about the backup before in a previous thread but didn't get an answer.... Sorry to ask again

And this will work with Sprint S8+ Correct? Lastly, since the latest update which included Sprint LTE Plus calling. We will still manage to have that feature after root right? Because boy do I enjoy being able to browse the internet and being on a call at the same time again lol

If you have the system.img for the latest update then correct, if not and you want those features with root you will have to download the AP and CSC from thw firmware you want

Installing LineageOS on my old Samsung Galaxy S6

I'm trying to install LineageOS on my old Samsung Galaxy S6 on which I have enabled developer options and USB debugging. I am not an expert in this but have at least made a little progress but I'm not confident and the remaining steps
The following describes the steps I have done so far on my old SONY VAIO laptop with Manjaro Linux installed....
https://wiki.lineageos.org/adb_fastboot_guide.html # Installed adb and fastboot
"platform-tools_r28.0.2-linux.zip" # download, extract & configure # done
Setting up "adb" # done, I can see "List of devices" when phone connected
Was able to boot phone into recovery mode, "Android Recovery" text only menu is displayed. I was not able to select and "Reboot to bootloader".
Was able to boot phone into "Download-mode" showing "ODIN MODE" top LH of text only screen
I have also installed following sofware on my laptop...
Code:
$ sudo pacman -Syu android-udev # installed OK
$ pamac build heimdall # installed OK
$ sudo heimdall print-pit # this produced a long list of partitions, then
# phone reboots to standard home screen.
$ sudo pacman -Syu android-tools # I decided to install this from stardard repos
# I wasn't sure if this was required or not.
I tried to root my phone following these instructions...
https://www.all-things-android.com/content/how-root-samsung-mobile-device
... and I was able to complete each step successfully until step 22.
... I just didn't get "Flash completed successfully!" message next to the progress bar at Step 22 of instructions.
I did get following message in the Status text area....
Code:

Power off the your device and connect the USB adapter to the computer (but not to the device, yet).
Boot into download mode: With the device powered off, hold Volume Down + Home + Power.
Accept the disclaimer, then insert the USB cable into the device.
On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window in the directory the recovery image is located, and type:
heimdall flash --RECOVERY twrp-x.x.x-x-zerofltexx.img --no-reboot
$ heimdall flash --RECOVERY twrp-3.2.3-0-zeroflte.img --no-reboot
NOTE: I haven't done this step yet because the next step is...
Installing LineageOS from recovery
Build a LineageOS install package.
which links to https://wiki.lineageos.org/devices/zerofltexx/build
where it talks about "Build LineageOS and LineageOS Recovery"
this looks very complicated for my limited knowledge of both Linux and Android flashing etc.
My questions:
1. Are my steps so far OK, anything missing?
2. Is there an easier way to do this, can I download a package already built, if so, where to go?
3. Phone is still not rooted yet. so is this a problem going forward?
4. Have I installed the correct software packages so far?
Any help / guidance would be appreciated. Thanks.

I think you need heimdall 1.4.3

Thanks for feedback @Kurtin. I can't see heimdall 1.4.3 in the Manjaro AUR repository, I only see heimdall 1.4.2
I'm not sure how to install a package unless it's in the repository.

Sorry, I don't know how to handle that in manjaro. Maybe you should try Odin on a windows PC instead.

Do it the EASY way .....
Suggestion - this is SO MUCH EASIER if you use Odin instead. ASSUMING you have a working Odin setup .....
Tick the box to turn off auto re-boot in Odin.
Flash TWRP.
Do the fast shuffle of fingers necessary to do the initial re-boot into TWRP - vol.down+power to reset the phone and then IMMEDIATELY when the screen goes to black vol.up+power+home to boot recovery. Make sure you hold the three keys down or you won't boot into TWRP.
Once you get TWRP in place, you are good to go. If you re-boot into stock recovery it means your fingers were slow or you didn't hold all three keys down. Repeat with faster or more patient fingers as necessary.
Which S6 variant ? If you have the 920F version, for instance, this is as easy as it gets. Some versions of the S6 are a bit more problematic, and it may be difficult or even impossible if you have a Chinese, HK, or USA Qualcomm model (AT&T, etc...) , but for the others, easy as pie as long as you have the correct TWRP file to flash. Check twice, flash once .....
Speaking of Pie, there is a very functional version of Lineage 16 for the S6. Not 100% perfect but getting there and completely useable (for me, anyway) as a daily driver.

How to go back to official firmware

Hii. I am ankit.
I have downloaded custom rom and twrp recovery.
Now i want to get back to stock rom and stock recovery in my phone.
And also wants to use official updates of phone's software.
Can anyone help?

1.Download the odin
2.Download rome orginal a50

Windows
The easiest way for Windows is to just use Odin. This is a nice tutorial on how to restore to stock with it.
Linux
If you use Linux and don't want to bother with trying to use something like Wine to run Odin, the following steps are for you.
Get the firmware
You can use something like updato.com, but from my experience it failed 2 separate 4 hour downloads, and the download speeds are abysmal, so I can't recommend.
I use samloader, the only caveat with it is that you can only get the latest firmware for a region (because Samsung only saves the latest one), you'll need to use something else for older versions.
1.1 Install samloader, following their instructions
1.2 Get your Model number, it should look something similar to GT-I8190N, if you don't know it, here is a link on how to find it (it's made for stock firmware, but it should still point you in the right direction)
1.3 Get your region (you might be able to install from any region, but I think it's safest if it's the region from which the phone is bought), here you can find a good list of available regions
1.4 Check the latest firmware version available. Use the following command, and replace the model and region with your values
Code:
$ samloader -m GT-I8190N -r BTU checkupdate
The output should be something like this:
Code:
I8190NXXAMJ2/I8190NBTUAMJ1/I8190NXXAMJ2/I8190NXXAMJ2
1.5 Download the firmware, whose name you got from step 1.4. Use the following command, again replacing the values with your own
Code:
$ samloader -m GT-I8190N -r BTU download -v I8190NXXAMJ2/I8190NBTUAMJ1/I8190NXXAMJ2/I8190NXXAMJ2 -O .
After it has finished downloading, the output should look something like this:
Code:
downloading GT-I8190N_BTU_1_20131118100230_9ae3yzkqmu_fac.zip.enc2
[################################] 10570/10570 - 00:02:02
1.6 Final step is to decrypt the downloaded firmware. To do so, use the following command, while again, changing your values. Important: after the -V, you put in a number, that number is dependent on the file you downloaded from step 1.5. If the file ends with .enc4, replace the number 2 with the number 4, if it ends with .enc2, leave it at 2.
Code:
$ samloader -m GT-I8190N -r BTU decrypt -v I8190NXXAMJ2/I8190NBTUAMJ1/I8190NXXAMJ2/I8190NXXAMJ2 -V 2 -i GT-I8190N_BTU_1_20131118100230_9ae3yzkqmu_fac.zip.enc2 -o GT-I8190N_BTU_1_20131118100230_9ae3yzkqmu_fac.zip
Unzip the firmware archive. You should do so in a new folder, as a lot of files will be extracted.
Code:
unzip GT-I8190N_BTU_1_20131118100230_9ae3yzkqmu_fac.zip
Extract the files from the files, you got in step 2 (yeah, there are archived files inside an archive). The following command does just that, you can simply copy-paste it
Code:
for file in *.tar.md5; do tar -xvf $file done
Finally, flash all of the resulting .img and .bin files. On how to find which file goes where, use these instructions. If you use Heimdall for flashing, in that link you can also instructions for it.

And if for example, I want to go back to Android 9, which is binary 5 and my A50 is Android 11, binary 7, is there any way I can ignore the binary or something?
