These were the steps that you had to follow in order to successfully update your phone.

NOTE: if ODIN fails to install XXUFNA5 Android 4.4.2 ROM, it freezes or for any other reason the installation doesn’t complete, then you will be forced to repeat the entire tutorial once again.

NOTE 2: in case ODIN says that the installation was passed, but the device is unable to boot in normal mode then you should apply a factory reset. Note that the ‘factory reset’ will wipe all data from your device’s system partition, while leaving the other parts of your device unaffected. Here’s how to apply a factory reset for your device:

  • Power off the device now completely.
  • Boot the phone in Stock Recovery Mode.
    – recovery mode for Samsung can be booted using the info here, that’s a guide for those of you who don’t know how to do it.
  • Select ‘wipe data/ factory reset’, then confirm the process.
  • Reboot your phone now in normal mode.
