Below are the official firmware build G900TUVU1FOG6 5.1.1 t for advanced users that cannot update their devices beforehand as it was already modified and now wants to manually update using the stock firmware.
How to Manually Install the G900TUVU1FOG6 5.1.1 Stock Firmware
• Make sure that your Samsung Galaxy S5 SM-G900T is recharge for 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 backup 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 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.
• 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.
• 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.
Important Note: The Android 5.1.1 firmware has a protected bootloader that might cause issues when you try to downgrade to the old software updates. This also applies if you are into rooting and installs any custom recovery or any unsigned firmware once you are on 5.1.1 Lollipop, so please be aware with that.
