FAQ’s on using the I9505XXUGNK4 4.4.2 Stock Firmware

Will this trip KNOX warranty void flag counter to 0×1?
Nup, this is an official and signed firmware from Samsung, so flashing official firmware will not trip KNOX.
My Galaxy S4 is rooted, will I lose root?
If your device is currently rooted you will lose root after flash, but you can still root it again if 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 Galaxy S4 is fully charge.
    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 phone’s 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 Galaxy S4.
  • Enable USB debugging from your phone’s settings – while if you are now on 4.4.2 just hit Settings>>About Phone>> then scroll down to the build number and tap that number for around 7-times ’til the Developer option appear.
  • 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.
  • The Android 4.4.2 KitKat now comes with a new protected bootloader that will result into unwanted issues when you try to downgrade to the old software updates. This also applies if you are planning into rooting and installs any custom recovery and any unsigned firmware once you are on 4.4.2 KitKat, so please be aware with that.

Install the USB Driver first to get rid of flashing failures. You may also need to extract the downloaded file which is packed in zip or rar files, so that you’ll get the tar.md5 file.

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.
