Install Android 4.4.2 XXUFNA1 Test Firmware for Samsung Galaxy S4 I9505 LTE

Samsung works on releasing the first Android 4.4.2 OTA Update for the S4 LTE device, but the official release date hasn’t been made public. However, you can find in this post instructions on how to flash a test Android 4.4.2 KitKat.

The official Android 4.4 KitKat OTA Update is expected in February or March. Until then you can update your device using the test firmware that I’ve listed in this article. The main changes spotted in this new ROM are as following: white status bar icons to suit the KitKat new UI, better performance, higher benchmark scores, quick camera shortcut displayed on the lock screen, improved keyboard layout and other minor changes.

Before starting the installation of the new I9505XXUFNA1 Android 4.4.2 KitKat on your Galaxy S4 LTE, you will first need to take a look at the preparation guide below:

  • Use this post only with the Samsung Galaxy S4 LTE model number I9505.
    – don’t attempt to update any other S4 variants with the files that you’ll find in this post.
  • Download and install the Samsung USB Drivers from here.
  • Disable the Samsung KIES app before starting the installation of the new leaked KitKat 4.4.2 firmware.
  • Disable all the antivirus applications that are running on your PC.
  • Enable the USB Debugging from Developer Options.
    – if Developer Options is not listed in the Settings menu, then you need to open About Phone section and then tap seven times on the Build Number text.
  • If you update the device and then it doesn’t boot in normal mode with the XXUFNA1 Android 4.4.2 firmware, then you will be forced to apply a ‘factory reset’ for your device.
  • If you want to backup any data from installed applications, then you should download and install Helium from the Google Play Store here.
  • Sync Contacts with your Gmail account.
    – guide here.
  • Backing up data isn’t important for users who are already running a stock Android ROM, but those of you running custom ROMs should backup important data.
  • This is a guide for advanced users, do not blame us in case you brick the device or lose any important data in the process.
  • Check your Galaxy S4 I9505 battery and make sure that that it is over 50%, so that the device won’t switch off in the middle of the updating process.
  • Read the entire post and make sure that you don’t skip any steps that I’ve listed in this post.
  • For any extra questions use the comments field.
