G925TUVU2COF6 T-Mobile Galaxy S6 Edge SM-G925T Official 5.1.1 Update Firmware

T-Mobile Samsung Galaxy S6 Edge SM-G925T stock firmware build version G925TUVU2COF6. This is the official Android 5.1.1 update bringing the Anti-theft Factory Reset Protection (FRP) as the main feature. The addressed changelog G925TUVU2COF6 5.1.1 update is the same as it goes on T-Mobile Samsung Galaxy S6 SM-G920T Android 5.1.1 update to build version G920TUVU2COF6. Though both is quite similar firmware build version but this specific build version is for the Galaxy S6 Edge G925T only.

Aside from Anti-theft features there are also new security settings called "OEM unlocking" which is quite a bit annoying since the T-Mobile S6 Edge hasn't had a locked bootloader.  The "OEM unlocking" function is optional of-course which can be toggle with an ON and OFF switch. The camera app is now also added with exposure slider that allows the Galaxy S6 Edge owners to adjust the photos to their desired brightness. While among the rest are bug fixes, improvements to some apps and stability improvements.

Yet, this particular G925TUVU2COF6 Android 5.1.1 stock firmware is for those folks who have had a rooted and modified T-Mobile Samsung Galaxy S6 Edge SM-G925T.  The stock firmware can be used to unroot, manually upgrade and to return back their devices to its official firmware or stock. If and when one has not been able to get the 5.1.1 update and it just says something like “The device has been modified in unauthorised way” and did not get the OTA update the way it used to be.

On a side note, the G925TUVU2COF6 Android 5.1.1 update cannot be rooted at this time being. So to those who have rushed-in into rooting but now ended-up into soft-bricks like just like stuck in a logo which the phone can’t boot normally and hangs in the logo screen. You can easily fix it by means of installing back the official Android 5.1.1 G925TUVU2COF6 firmware.
Reminder: The G925TUVU2COF6 cannot be rooted with CF-AUTO ROOT and PINGPONG ROOT! So refrain from rooting or else your device may only end-up into bootloop or just stuck in Samsung Logo. Once installed or been updated to Android 5.1.1, you cannot downgrade back to Android 5.0.2 G925TUVU1AOCG stock firmware.

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 Edge, 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.

Again, this stock firmware is specifically for the Galaxy S6 Edge with model number SM-G925T a T-Mobile retail version only. Do not play it around on any other Samsung Galaxy S6 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.
2) Run Odin Downloader v3.10.6 flasher program.
3) Do Not check the Re-Partition checkbox. Mark check these check boxes Auto Reboot and F-Reset Time and nothing else.
4) Reboot the phone in download mode: To reboot the Galaxy S6 Edge 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: “G925TUVU2COF6_G925TTMB2COF6_Home.tar.md5″
7) Hit the “START’ button if everything seems all good to start flashing.
8) Wait until you see the huge word “PASS!’ .
9) Disconnect  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.

For fixing bootloops and stuck in logo:
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. Re-flash the stick firmware if necessary.
