Install I9505XXUGNF1 Android 4.4.2 Update Manually for Samsung Galaxy S4 LTE I9505

A new Android 4.4.2 KitKat build has been released for the Samsung Galaxy S4 LTE I9505 smartphone, use this post if you want to learn how to successfully install it on your device.

With the brand new ROM you will be able to get the latest Android 4.4.2 features and elements that should improve your Android experience. This is a great guide for users that didn’t receive the official Android 4.4.2 XXUGNF1 OTA Update on their Galaxy S4 smartphones. Use this post for manual installation and before you get to the tutorial you should first take a look at the preparation info below:

  • use this post only with the International Samsung Galaxy S4 LTE model number GT – I9505.
    – do not try to use this post for any other Android devices.
    – check the model number of your Galaxy S4 by going to Settings> About Device.
  • make sure to install the Samsung USB Drivers on your PC before starting the update.
  • enable USB Debugging from Developer Options menu.
    – in case Developer Options is not enabled on your PC you will have to enable this option first.
    – learn here how to enable Developer Options and USB Debugging; that’s a guide for Galaxy S5, but it works 100% for all Samsung devices.
  • disable the Samsung KIES and antivirus apps from running on your computer.
    – these apps might interfere with Odin, the app that we will use to install the new update.
  • if your phone is rooted, then the updating process will revoke root access.
  • if you’re currently running a custom Recovery, then it will be replaced with a stock Recovery.
  • if your device has a custom ROM installed on it you will get all the system partition wiped in the process.
    – note that the system partition will be wiped only, but you will have to apply a ‘factory reset’ after the installation is complete; more info is listed at the end of the tutorial.
  • in case you want to backup data from installed applications, use the Helium tool for Android.
  • sync Contacts and People details with your default Gmail account.
  • use this post only if you’re an advanced Android user.
  • don’t blame us in case you brick the phone nor in case you lose any important data in the process.
  • check the Galaxy S4 LTE battery charge level and make sure that it is over 50%, this will prevent it from switching off during the updating process.
  • read the whole guide and make sure not to skip any steps.

Since you’ve read all of the above, now you’re free to continue to the next part of this article.

    – note that the first boot process takes at least ten minutes, so you shouldn’t panic.

I hope that you’be managed to update your device and that you are currently testing all the new features.

If you’ve encountered any problems during installation you should take a look at the ‘notes’ below.

NOTE 1: if Odin fails to install all fails, it freezes or something else goes wrong, then you will have to repeat the guide more than once. Also, make sure to re-install the Samsung USB Drivers and use the comments field to ask for extra help.

NOTE 2: In case Odin says ‘PASS’ confirming that the update was complete, but your Galaxy S4 LTE doesn’t load all the Android 4.4.2 XXUGNF1 firmware files and it gets stuck at the boot animation for more than 20 minutes, then you will need to apply a Factory Reset.

The Factory Reset process has to be used for devices that were running Android custom ROMs, too. Here’s how to apply the factory reset:

  • power off the phone complete and then boot it in Recovery Mode.
  • select ‘wiped data/ factory reset’.
  • confirm process.
  • after the factory reset is complete you should reboot the phone in normal mode.

These were all the steps that we had for you, if you need more help use the comments field below.
