Since the update has just recently rolled out via over-the-air OTA update and thru Samsung Kies. But it is only mostly convenient for those who did not root and modified their SGS 5 SM-G900T.  But for those who a got a rooted devices and might want to restore back to the official firmware then you can manually install the official G900TUVU1DOB1 5.0 stock firmware below.  Just read on the whole procedures on how to manually upgrade you Galaxy S5 G900T to official Android 5.0 Lollipop.

FAQ’s About Installing the Stock Lollipop DOB1

Does it tripped KNOX warranty flag counter to 0×1?
No, this is an official and signed firmware from Samsung, so flashing official firmware will not trip KNOX warranty void counter from ‘0x0 to 0x1′.
My Samsung Galaxy S5 SM-G900T is rooted, will I lose root?
Yes, you will lose root after flashing the stock Android 5.0 Lollipop  as it will return back your phone to official state. But you can still root it again anytime you want.

Disclaimer: Use of this method is solely at your own risk! Please proceed with precautions, for we will not take any responsibility if anything happens to your device by using this guide.


• Make sure that your Samsung Galaxy S5 SM-G900T is recharge or at-least 40% remaining battery power.
• Stock Firmware packages comes in two formats the ‘Full-Wipe’ (delete your stored data after flashing) and the ‘Non-Wipe’ (it doesn’t delete your stored data) but it is highly recommended to make a back up all important files stored from your phone’s internal memory – contacts, messages, etc. before flashing no-matter if it is Full-Wipe or Non-Wipe, just to be safe and ensure that your stored data are in safe if something went wrong during the flashing process.
• Use the supplied USB cable for your Samsung Galaxy S5 SM-G900T.
• Enable USB debugging from your phone’s settings – Settings>>About Phone>> then scroll down to the build number and tap that number for around 7-times ’til the Developer option appears.
• Use a PC or laptop that runs in Windows OS, with a good and perfectly working USB serial port. Odin will not work on MAC OS.
• Ensure that KIES is closed and not running in the system tray! Kies and Odin are both created by Samsung but Kies will interrupt and doesn’t like Odin, it will block you from flashing.

Run and Configure Odin

Run Odin downloader Odin3_v3.09 on your PC desktop. Watch out the check-boxes options on the right top of Odin, ensure that the ‘Phone Bootloader Update’ (only if your device runs on 4.3) , ‘AUTO-REBOOT’ and ‘F.RESET TIME’ checkboxes must be checked. Only the ‘RE-PARTITION’ is unchecked.

Reboot your Samsung Galaxy S5 SM-G900T into Download Mode

Wait until you see a ‘PASS!!’ message

When the Stock Firmware installation successfully completes, you will then see a word “PASS” in Odin. This indicates that the flashing was already finish, and on the log box it says “All threads completed (succeed 1 / failed 0)”. The phone will just then automatically reboot, then it’s about time to remove it from PC or laptop USB connection.

Go to Settings>About Device>Firmware info.

Possible errors that you may encountered, this is based on my own experience while flashing stock firmware on Samsung Android devices. These are just a few hints on how to resolved it.

Q: I got an error message that says “Set-up connection Failed” ?
A: 1. Check your USB connection from the phone to PC,
2. Connect to another PC USB port
3. Check and or try to another USB cable
4. Re-install the USB driver.
Q: Odin just suddenly stuck in the middle of nowhere while in flashing progress, it isn’t responding at all?
A: Check for possible program that might interrupt the process, like disabling the anti-virus and closing any running programs. Also try to use another computer or laptop,
Q: I experienced bootloop or the phone just stuck on Welcome Logo (phone always stop at bootanimation) and it won’t boot normally?
A: This eventually happens if your device came from custom firmware but you can fix it via by performing factory reset in recovery mode:

Ensure that you already saved a back-up copy of all important data stored from the phone. This process will delete all data so keep that in mind.
1. Press and hold Volume Up, Home and Power button.
2. Use volume keys to scroll. Power or Home key to select the option.
