Before You Start

• This tutorial is meant to be only applied on T-Mobile Galaxy S6 SM-G920T. 
• If you phone is rooted and custom recovery is installed then after flashing the device's root access will be revoked and custom recovery will be replaced with stock recovery.
• Backup all of your data stored in the internal storage of the phone and save a copy to your computer.
• You can backup app data by using app data backup and restore apps.
• Enable 'USB Debugging' in developer options.
• If 'Developer options' is not visible then go to 'Settings>About device'. Here tap the 'Build number' 10 times to unlock the 'Developer options'.
• As I said that this is an official update guide so you won't loose any data, but still you have to backup data, in case if something goes wrong then you have the data backup.
• The tablet's battery should be charged to 60% or above.

• Download and install Samsung USB drivers from above link.
• Download odin and T-Mobile Galaxy S6 ROM and extract them in separate folders on desktop.
• You need to create a free account at Sammobile to download the ROM.
• Now switch off your Galaxy S6 and reboot it in download mode by pressing 'Home+Power+Volume Down' key at the same time.
• Release the buttons when the phone vibrates.
• Press volume up button when you see a warning page. Now you have entered in odin mode.
• Now launch odin.exe on your pc.
• Connect the phone to computer via USB cable.
• Let odin recognize the phone.
• When it is identified by odin the field under <ID:COM> in odin will turn blue and you will see a message "<ID:0/016> Added".
• Make sure that only "Auto Reboot", and "F.Reset Time" options should be checked. Do not change other settings of ODIN.
• Now check 'AP' and click it and select the firmware file G920TUVU2COF8 tar.md5 Android 5.1.1 file from the folder where you saved it.
• Wait for few seconds till ODIN finishes some checks.
• Click 'Start' to initiate the flashing process. When the process is completed odin will return a message 'PASS'.
• When your phone first boots to home screen (may take longer, 15 minutes or more) then disconnect it from PC.  Now check the android version in 'Settings>About device>Android version'.

Troubleshooting

• If ODIN fails in between, then repeat the procedure. However it hardly happens.
• If after updating to G920TUVU2COF8 android 5.1.1 you see that your phone  has become slow or doesn't booting to home screen even after 20 minutes, then do a factory reset in recovery mode.
• Before doing factory reset, make sure you have backed up your personal data.
