Here is the stock firmware G920TUVU1AOCG tarball for T-Mobile Samsung Galaxy S6 SM-G920T.  It's an Android 5.0.2 Lollipop base as we knew it and it's the initial OTA update replacing the shipped firmware build version G920TUVU1AOC9 to fix some issues. The stock firmware is for advanced users and tinkerers only,  since the T-Mobile's Samsung Galaxy S6 SM-G920T root is now also available. This can only be use to unroot the device if one has not be able to get the update and it just says something like the device has been modified, there is no software update is available, and you cannot get the update anymore.

Stock firmware have had been also useful enough if one had messed-up from rooting and modification. Once the device ended-up into soft-bricks like stuck at welcome screen logo, bootloops, just think about that the stock firmware is your pal. So don't bother anyone else to ask for help because it was your fault,  fix it on your own by means of Odin'ing back the official, unmodified factory stock firmware into your phone.

How to Flash:

Disclaimer: Use of this guide is solely at your own risk!


– Make sure your phone is fully re-charge to avoid power interruption and flashing failure.
– Optional: Back up all important files stored from the phone’s internal memory such as contacts, photos, videos, MMS, SMS, emails, docs etc. Though, most stock firmware is non-wipe but in some circumstances if the flashing goes wrong it will delete all of your files.
– Optional: Perform factory reset to gain a smooth firmware flashing without failures especially if the device is rooted and running in an unofficial firmware.
– Used Windows-based computers, Odin will not run on Mac.
– Disable any running program on system tray, to avoid program conflicts and failures.
– Used the supplied USB data cable of your Galaxy S6, flashing failures is mostly caused by bad USB cable. So, make sure you have a perfectly working USB data cable.

Grab the necessary files for manual flashing.
– Install the USB driver for Samsung Galaxy S5 just download and install Kies as it includes the needed USB driver or grab it here.

Again, this stock firmware is specifically for the Galaxy S6 with model number SM-G920T a T-mobile retail version only. Do not play it around on any other Samsung Galaxy S6 and variants or else you may wonder why. I warned you.


1) Extract or unzip the downloaded firmware, Odin flasher program can’t read it until you’ll get the correct file path which is in (.tar) file format. You can use ’7zip’ or ‘winrar’ to do that task, I used winrar.

2) Run Odin Downloader v3.10.6 flasher program.
3) Do Not check the Re-Partition checkbox. Mark check these checkboxes Auto Reboot and F-Reset Time and nothing else.
4) Reboot the phone in download mode: To reboot the Galaxy S6 into download mode , you need to turn the power off.  Once completely shut down, just press and hold the Volume Down key, Home button and the Power button at the same time.
You should then prompted into a warning screen and asking you to press Volume Up if you want to continue or volume down to cancel, just simply press volume up to get into download mode. The download mode screen displays a box and say’s “Downloading.. Do not turn off target!!”

5) Connect the phone to PC when it’s only in the Download Mode screen. You should notice that the ID:COM box on ODIN will turn to blueish and will show you the port (COM) number.
6) Click on the AP button then browse to the folder where you extracted the stock firmware.
AP: “G920TUVU1AOCG_G920TTMB1AOCG_Home.tar.md5″
7) Hit the “START’ button if everything seems all good to start flashing.
8) Wait until see the huge word “PASS!’ and not Failed!.
9) Remove the phone from the computer once it has completely reboots.
10) Optional: perform wipe data or factory reset to again.

Fixing possible failures on Odin:

If you ain’t see the word ‘PASS!’ and it says ‘completed 0/failed 1′, all you need is just repeat the procedure above.
If it still fails, check the following again,
– Try to use other USB cable.
– Try to use other computer USB port.
– Try to use other desktop/laptop computer.

Fixing bootloops: 

If you have bootloop or stuck on welcome screen logo on first reboot. Just perform a full data factory reset as this issues usually happens when your phone came from a modified system images, such as rooted kernels, custom recoveries and unofficial firmware and you forgot to perform wipe data before restoring to stock.
– Wait a couple of minutes as the firmware installation still refreshing.
– If it continuous on an hour, perform a factory reset via recovery.
Just hold down Volume Up, Home and Power button at the same time. Once the phone displays the recovery options scroll down using the Volume keys and then select Wipe Data/Factory reset.
