Linux is your friend! I was more successful using Linux to boot the phone, each time without issue. Windows is problematic with the Samsung drivers.
[AT&T Samsung Galaxy S6] Holhat:
I don't even know what you mean by Linux. I followed directions, got the green PASS and now my phione doesn't even come on :confused:
[AT&T Samsung Galaxy S6] metalcated:
Your phone does not power on at all?
[AT&T Samsung Galaxy S6] Holhat:
does now. I can get to download mode again. W

hen I tried hard reset, I n oticed it said system cannot mount
[AT&T Samsung Galaxy S6] metalcated:
What rom version are you running?
[AT&T Samsung Galaxy S6] LHTrung:
Can you re-post a clearer help? Can't follow your step! And do not understand what file for the version OJ7 or OJ9...
[AT&T Samsung Galaxy S6] rapidrayo:
Did somebody resolve the problem? Because when I sucsesfully root the phone but when I try to reboot the phone doesnt come on, it just appear the samsung logo and then a black screen, I can enter to the recovery mode and do a factory reset from there but I got the same result a black screen, what can I do, somebody help me :(
[AT&T Samsung Galaxy S6] xdaninja:
please read the thread. any time you need to reboot the phone, it needs to be connected to the computer and run the root script again
[AT&T Samsung Galaxy S6] metalcated:
Thanks, honestly I've begun to ignore posts that are related to the risks clearly documented in the OP. Sorry folks if that seems shallow, but it gets old answering the same questions over and over when I made things clear in the OP.
[AT&T Samsung Galaxy S6] JacobFreakingHarris:
Instructions Unclear for OJ9

What is the order for flashing and running root-install? The original post said "Using the same steps as above to Flash the downgraded system partition" so I'm not sure if you meant we have to flash the md5 file. Do we flash the md5, the tar, and then run root-install? Flash tar and then run root-install? Flash the md5, run root-install, flash the tar, and then run root-install? If we don't have to flash the md5 for oj9, you should add a header on the OP for oj7 exclusive steps.
[AT&T Samsung Galaxy S6] metalcated:
The md5 as you say is the stock image for OJ7 or OJ9, I provided both depending on what you have on your phone. It's not needed unless you soft brick or get to a point where it's too much of a pain to be boot tethered and you want to return to stock. Know this though, flashing the stock images will wipe your device including the sdcard.

Steps are simple as laid out in the OP. If your on OJ9, then I recommend flashing the OJ7 tar I provided that contains only the system and boot image, this will not wipe your device. If your already on OJ7, then flash the OJ7 tar that only contains the boot image. Then once done and booted up, run the install-root file, reboot and 9x out of 10 the first boot wont show SuperSU working. You can reboot again and then you should see it working. But to reboot you'll need install-boot to do so, recommended to use on Linux as Linux is more reliable, windows drivers are crappy and cause issues. Ok. That should be it. This is the last time I am going to walk someone through this, I've done it so many times. Hope this helps.
[AT&T Samsung Galaxy S6] rapidrayo:
I did that, and the phone doesnt do anything, its still in the loop, Idk if the phone first need to be conected or if I need to run the script first, if you can help me I will really appreciate that.
[AT&T Samsung Galaxy S6] VegasJoker:
If you don't know what you are doing or bother reading the OP than why attempt this? Anyway, yes plug the phone in then run the script.
[AT&T Samsung Galaxy S6] rapidrayo:
Thank you it works.
[AT&T Samsung Galaxy S6] AllThoseDamnWeedos:
I've got the root working, but how did you manage to install Xposed? I tried it via Flashfire due to AT&T'S locked bootloader, and it appeared to be installing it, but when it was done, I got the "unauthorized software" message. I reflashed OJ7 and rooted it again, but I don't want to risk another soft brick. Instructions would be greatly appreciated.
[AT&T Samsung Galaxy S6] metalcated:
Check the OP...
[AT&T Samsung Galaxy S6] DODGraphics:
This worked perfect for me. I had to get a replacement S6 that came on BOJ9. Followed the steps and everything is working great. Thank you! I have a G920A and windows 10. I haven't had any hangups, it reboots perfectly. I can reboot through shell or on the device, then while screen is black run the root-Boot.cmd, takes about 30 seconds to say "booting", and boots right up. The only issue I am having is the "Security Notice, Unauthorized actions....." popup. Anyone find a solution to this?

Also to the OP, have you gotten anywhere with the untether?

Thanks again
[AT&T Samsung Galaxy S6] metalcated:
As far as security notice, you can flash the OJ7 system that is pre-rooted and debloated to help with that or try and debloat yourself. Flashing the system image should have no effect on your current install. Data should be safe, but always make backups. Flashfire is your friend.
[AT&T Samsung Galaxy S6] DODGraphics:
How do I flash using the debloated file? Sorry I am pretty new to Android so I'm not familiar with all this yet. Thanks again
[AT&T Samsung Galaxy S6] PWShoes:
I'm lost

I didn't read all the comments due to a nonresponsive script that makes it near impossible to navigate this site, so I don't know if this was addressed, but I am stuck at the at&t logo after what seemed like a successful root. I'm on windows 10 and adb wasn't connecting. I uninstalled adb interface in device manager and reinstalled it and after restarting my computer it connects, but my phone doesn't respond when I run through root-Boot.cmd. When I run through root-Install.cmd again, adb doesn't connect. Disabling/enabling adb interface in device manager and/or scaning for hardware changes does nothing
[AT&T Samsung Galaxy S6] metalcated:
Welcome to Windows! Linux works much better but I know not everyone uses it. However, this is the root method and these are the challenges. The suggested steps are in the OP.
[AT&T Samsung Galaxy S6] PWShoes:
And scared

Do you know if my phone will be okay if I hold vol up, power, and home and select factory reset from there?

---------- Post added at 08:48 PM ---------- Previous post was at 08:23 PM ----------

So factory reset didn't work. If I flash a stock firmware to reset it (I downloaded the recovery thing you posted here which I'm assuming is the same as stock firmware) do I flash all four files at once? And if so how because the CP and CSC slots in Odin are greyed out for me and no options change that.
[AT&T Samsung Galaxy S6] metalcated:
All you need is the OJ7 system.img tar'ed up which is all ready to go and posted in the OP.
[AT&T Samsung Galaxy S6] abduct0r:
Thanks Metalcated!!! Been loving this root! Now how do I upgrade to Marshmallow without losing root or bricking phone?
[AT&T Samsung Galaxy S6] metalcated:
Not possible at the moment. I also haven't even tried to do anything with Marshmallow yet. I may wait for a bit before I attempt anything with Marshmallow.
[AT&T Samsung Galaxy S6] Guardian x9:
ah i was stuck at the Att log and i did the the delete driver and it works .. cool.. anyone that want to do the debloate the file structure on the phone should look like this or else

flashfire wont see it. \FlashFire\Backups\g920a-5.1.1-rooted-debloated-metalcated. im not sure if this is related to this thread but when i tried to turn on mock location so i can use fake gps.. it keep turning off everytime i try to activate it..// after i back out of developer menu.. basically i want to use the fake gps to cheat pokemon go lol

Terminal Emulator?

[MENTION=2835049]metalcated[/MENTION]

I just got an AT&T SGS6 (G920A) with OJ9 to play with. The first thing I looked for was root and found this thread. I'm having some issues with my Win10 box and getting this to work successfully every time. Unfortunately when I try to do "adb devices" within the BASH shell in Win10 it doesn't see anything attached. On the same PC it works fine within the Windows command prompt. I'm gonna see if anyone has any tips for that.

What I'm wondering is, could you put these scripts on the phone itself and use something like Terminal Emulator to install or reboot the phone instead of using your PC? I'm gonna give this a shot once I can get this !@#!@#$ phone to boot up properly again. :D

One more thing. If the phone freezes at boot is there anything you can do other than reflashing the kernel via Odin? If not, that's fine. I'm just wondering if I can speed up my testing.

Thanks,

Aaron

I have been noticing that I am getting more and more random reboots and lag on this ROM. I have had it installed for several months, but it seems to be jumping from H+ to E+ to 4G in the same areas more often than it was. Does anyone know if this is due to radio updates in MM or have thoughts on this?
[AT&T Samsung Galaxy S6] JUSMEJOSE:
You can also unroot and flash stock boot.img and should be good to go ..

[AT&T Samsung Galaxy S6] LordFrogz:
im still on a0f3, is it possible to root, upgrade, debloat and restore the phone to self booting? i regularly run my phone dry and cant always be by a computer ~Frogz

You can run this root method, debloat and then unroot yes. OP describes this as working and also in several of the user posts in this thread.

The non-engineering boot.img is fine.

So I was having the same issues as you but I was able to fix the issue by disabling SecurityLogAgent through the applications menu. The stock menu will not let you totally disable it but you can at least shut it down during the time you need to get the roots installed. I hope this helps

Hi [MENTION=2835049]metalcated[/MENTION]

I read all posts from this thread ((literally)).... and this answer here and this part of OP " since we cannot unlock the bootloader and flash an unsigned kernel" kinda answers my issue.... i will tell what is happening and tell me if it can be done...

My mom went to US for a few days and purchased an AT&T second hand Galaxy S6... so far, so good... but, we are brazilians and she don't read english, unfortunately... she only reads portuguese.... that said, there is only a few languages on the phone to chose and portuguese is not one of them... so, what I was thinking

This device is OJ9, so I have to ""downgrade"" it to OJ7 (right?) and than root it.... right?

Ok... but, I want to root this device to flash a Samsung Marshmallow ZTO stock rom ((Brazil version))... there is no need to keep the root after this be done. I only want to root this device to flash this Marshmallow ZTO rom and nothing else... is this can be done or it will brick the phone forever?

I've been reading in other forums when someone flash AT&T Marshmallow version, the device gets locked outside US... so, that's why I cannot flash an AT&T rom =\, only Samsung stock rom...

Is it possible to do this??

I appreciate any help here...

Cheers =)
[AT&T Samsung Galaxy S6] metalcated:
Unfortunately it's not possible since Samsung bit locks the device partitions. If you try to flash a ROM that does not match one of those "bits", doing so will fail.
[AT&T Samsung Galaxy S6] soulburnerms:
even with a samsung stock rom? a clean one? =(
[AT&T Samsung Galaxy S6] metalcated:
The stock ROM has to be for this specific model or it won't flash or boot. If you're using ODIN, I'll tell you when you try and flash if it works or not. If flashing using FlashFire, it may flash but your phone will softbrick if it's not the right ROM.
[AT&T Samsung Galaxy S6] soulburnerms:
This is a bad sad news..... unfortunately there is no lights on the end of the tunnel for this device yet... right? She loved the design of this device, but, with this last and final result, there is no other option rather than sell it to someone and purchase a new one....

Well, thanks very much for your help =)
[AT&T Samsung Galaxy S6] soulburnerms:
[MENTION=2835049]metalcated[/MENTION].... sorry to bother you again... but, i was reading your reply again "" If you're using ODIN, I'll tell you when you try and flash if it works or not."".... so it may works or not?

can I root this device and try to flash it and see if it will work or not? right?

If not works, is there a really safe way to get back everything as before? If yes, i can try it here now and tell you if it works =) ... or not =(

So, if everything went wrong, at least I can sell this device later or see what I can do =)

[AT&T Samsung Galaxy S6] dryes:
I finally got around to do the op procedure on my OJ7 S6, and I was pretty successful and was able to root the phone at some point. After a few reboot (using root-Boot.cmd) now I'm stuck at the att logo screen. The root-Boot.cmd can not save me any more...

I'm on win7, I was able to connect my phone to it but now it always say "device driver was not successfully installed". Tried to uninstall the "MTP USB device" and scan to reinstall, does not work. Tried to reinstall Samsung driver, doesn't work either. I notice that while it is searching for driver, root-Boot.cmd seems to be able to connect to phone and it will show "booting". But then the phone will still stuck at logo screen. I ran the root-install.cmd too and that runs successfully.

What is my problem? Thank you!

i followed every step, my phone restarted after rooting it with odin, but stuck on samsung logo, i ran the root-install, it didnt work, i ran the root-boot. it didnt work to, please help
[AT&T Samsung Galaxy S6] metalcated:
Fella's. If on Windows... it doesn't work as good and sometimes does not pickup the queue where it is supposed to send the command turn make selinux permissive and allow the system to boot. I have explained this over and over again throughout this thread. Linux unfortunately is your best choice. Once you get the phone debloated and maybe install an ad blocker, I suggest you un-root to avoid the tethering headache. And quite honestly, I don't recommend staying on such an outdated version due to security concerns. But ultimately that is your choice. Good luck.

Hello! I have the same problem...

How I can unroot Samsung to factory os?
[AT&T Samsung Galaxy S6] Teracotta:
I flashed G920AUCU3BOJ7_User_Binary.rar and the phone doesn't boot.

Is this not a stock, or is it the rooted binary?
[AT&T Samsung Galaxy S6] Teracotta:
Do I need to be on G920AUCU3BOI2 to allow root, not possible if I upgrade G920AUCU1AOCE directly to G920AUCU3BOJ7?
[AT&T Samsung Galaxy S6] metalcated:
Use the factory images in the OP. OP explains how to do this.

It's not a pre-rooted binary image. That's a stock image but it's the version needed to obtain root.

Honestly at this point I don't fully remember which version you can roll back from. Once the phone has been updated beyond a certain point, you can not longer roll back. It bit locks the bootloader. This should all be explained in the OP plus I no longer have this device to provide support.
[AT&T Samsung Galaxy S6] Teracotta:
It works with G920AUCU3BOI2, tremendous job BTW.
[AT&T Samsung Galaxy S6] Teracotta:
I have done some research.

It appears OJ9 and OJ7 have the same bootloader bit increment. I was able to downgrade OJ9 to OJ7 baseband without any problems.

The Lolipop firmware does not properly support carrier aggregation. I tested 5.1.1 against 6.0.1 in various sites and the 6.0.1. links everywhere, while 5.1.1 only does under specific circumstances and not in all sites. This is disappointing because 5.1.1 is the only firmware with a full root. The 6.0.1 shell root method cannot obtain write permissions to the system partition.

I had hoped the OJ9 baseband would give different results from OI2, but that does not appear to be the case.

If you flash a newer baseband on an older firmware, you will corrupt your eMMC flash memory, as bad as a hard brick. You can flash an older baseband to a newer firmware, but not the reverse. 5.1.1. can, apparently, be downgraded without problem.

It might not be a hard brick as the efs looks intact, others have found success on older phones in getting the baseband to remount the efs file, but I have not found success.
[AT&T Samsung Galaxy S6] Teracotta:
metalcated, I know you do not have the device anymore but I've found that the root is incomplete. I cannot push or pull files to the /sys/ folder, specifically /sys/class/power_supply/battery/.

However, on a locked bootloader Galaxy S7 also using a combination firmware, access is restored. So, I believe the problem is that the su binary is outdated and needs to be updated. I have a version of su that works on the Galaxy S7, can you swap out the SuperSu you are using in it for the updated binary?
[AT&T Samsung Galaxy S6] Mallos31:
Update?

Have there been any updates on this? I am currently unable to even install TWRP on my 7.0 Galaxy S6 so I'm curious to see if anything is possible yet.
[AT&T Samsung Galaxy S6] dandrumheller:
If there were updates, this is where they would be. Unlikely we'll see anything more on this device, since I'm fairly sure all the devs have long ago moved on, and as of yesterday's announcement Samsung has ended update support.

If you want root, go get an unbranded something with official bootloader unlock support.
[AT&T Samsung Galaxy S6] Mallos31:
Interesting. I'm just trying to modify a few things on this since I just bought it. I dumped everything from my old phone using Titanium Backup and needed to move it to this phone since the old one literally burned up.

Hola a todos, quiero agradecer al creador de este post porque con su ayuda pude rotaer mi telefono Samsung S6, g920a AT&T, android 5.1.1, numero de compilacion g920aucu3boj7, banda base g920aucu3bo12 y lo mas importante funciona a la PERFECCION.-

Para aquellos que tienen problema le dejo el metodo que utilice:

1.- genere un archivo tar con el boot que se encuentra en el archivo "g920a-5.1.1-root_metalcated-v4" y con el syst que se encuentra en el archivo "AP_G920AUCU3BOJ7+G920A_Kernel_Root_5.1.1".-

2.-cargan ese archivo en Odin en AP y le dan a start.-

3.- cuando el telefono se reinicia inmediatamente hacer corren en CMD el comando "root-install" .-

4.- al reiniciarse el telefono se cargo la aplicacion "superSU" y aqui viene lo mas IMPORTANTE.-

5.- al darle click a superSU les va aparecer un mensaje de error diciendo que el telefono no esta roteado porque no se cargo un binario, pero aca viene lo mas IMPORTANTE para que el telefono termine de rotearse: CUANDO APARECE ESE MENSAJE CIERRAN LA APLICACION E INMEDIATAMENTE LE DAN SEGUIDAMENTE VARIOS CLICK SIN PARAR Y A LOS SEGUNDOS SON USUARIOS ROOT.-

Espero que les sirva de ayuda y muchas gracias por ayudarme a rotear mi telefono.-

Your method I have a question

Hi I have done something similar but rooted with kingroot 4.8.2. My question is with the method you have to install SuperSU after flashing a custom ROM will you still have run your root-install.cmd to make the phone boot?

My phone was originally android 6.0.1 with n920a 4pb2 I think the last 4 digits.

Thank You for your information
