FAQ’s About Installing the G900TUVU1CNK2 Stock 4.4.2 Firmware

Will this trip KNOX warranty void 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 firmware. 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.

Prerequisites

• 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 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 4.4.2 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 4.4.2 KitKat, so please be aware with that.
