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.


• 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.

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.

Your COM port number might be different from mine. If you do not see a COM port number then there’s something missing or wrong. You may read again from the top of this post.

Start Flashing the stock firmware

Once if all set and ready to fire-up, hit the “START” button in Odin to begin flashing the stock ROM. Do not ever interrupt the flashing process, such as disconnecting the cable or turning off the device. Just wait until it completely finish.

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 Phone>Firmware info.

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?
