Restore back T-Mobile Galaxy S6 to stock build G920TUVU3DOI1. This firmware update is not an Android 6.0 Marshmallow yet but still remain in Android 5.1.1 Lollipop base. The G920TUVU3DOI1 brings various bug fixes and improvements but mainly address to install the newly updated version of the Samsung Pay. So those who weren't been able to get the update if your device has been rooted, you can manually download and install the G920TUVU3DOI1 stock firmware.

G920TUVU3DOI1 OTA Update firmware

But before you may proceed, allow me to make all thing to be clear here. Now, to be able for your device to get a working Samsung Pay, your Galaxy S6 KNOX app should have not been tripped off. If the KNOX counter was tripped, that also means that the Samsung Pay is already lost. The Samsung Pay will only stay working on devices that have kept the KNOX still intact. This will only work to those who have rooted their devices without actually tripping the KNOX counter but hasn't been able to get the update as the error message flagging the system saying "Your device has modified in an authorized way" and something like that.

Changelog details of the G920TUVU3DOI1 5.1.1 update:

  • Samsung Pay update

  • Various bug fixes and improvements

How to Install the G920TUVU3DOI1 5.1.1 stock firmware:

  • (Optional) Backup all important files stored from the phone’s internal memory such as contacts, photos, videos, MMS, SMS, emails, docs etc. Though, a most of stock firmware is non-wipe but in some circumstances if the flashing might go wrong it will delete all of your files.

  • Use 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.

Download Odin Odin3_v3.10.6 here

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


Disclaimer: This is an advanced users method. Use of this guide is solely at your own risk!

  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 a (.tar) file format.

  2. Run Odin3 v3.10.6 flasher program.

  3. Do Not check the Re-Partition check box. 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 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.

  5. 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 says’s “Downloading.. Do not turn off target!!”

  6. 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.

  7. Click on the AP button then browse to the folder where you extracted the stock firmware. AP: “G920TUVU3DOI1_G920TTMB3DOI1_G920TUVU3DOI1_Home.tar.md5″

  8. Hit the “START’ button if everything seems all good to start flashing.

  9. Wait until you see the huge word “PASS!’ .

  10. Disconnect the phone from the computer once it has completely reboots.

  11. Optional: perform Wipe data / 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:

  1. Try to use other USB data cable.

  2. Try to use other computer USB port.

  3. Try to use other PC

For fixing bootloop and stuck in Samsung logo:

If you have bootloop, stuck at the welcome screen logo on the 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 insist 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 stock firmware if necessary.
