Samsung Galaxy S4 LTE gets its second Android 4.3 Jelly Bean firmware update leak. Use this tutorial if you want to test the new features and functions before the official release is here. Note that this article is for users who like to tinker with their devices and ready to lose data files in the process.

Since this is the second leak of Android 4.3 Jelly Bean with build number set to XXUEMJ3, we can expect Samsung to launch an official stock OTA Update of Android 4.3 for Samsung Galaxy S4 LTE I9505 soon. The update should be ready for a late October release. If you want to successfully flash this stock test firmware, then you should first take a look at the guidelines and extra info below:

  • Use this post only for the Samsung Galaxy S4 model number I9505. This is the International LTE device, which means that the United States Galaxy S4 LTE models are not supported by this leaked firmware.
  • Do not attempt to update any other smartphones with the files you find in this post.
  • If your device is rooted, then you should know that installing this new firmware, then you will lose root, but the warranty will be restored.
    – any custom recoveries, custom kernels or any other type of customization you’ve installed on your SGS4 LTE will be removed in the process.
  • Phones that are on stock firmware will not get their warranty voided.
  • Binary counter will not be raised by this new firmware installation.
  • KNOX Warranty Counter will not be triggered by the XXUEMJ3 Android 4.3 installation. ( the 0x0 will stay 0x0 after you flash the new firmware)
  • This is not an official Samsung update, but a test build. It might contain errors or bugs and it might not be as stable as the official OTA Update.
  • Download and install the Samsung USB Drivers for your smartphone from here.
    – if you don’t install the drivers, then the Galaxy S4 I9505 will not be recognized by Odin, that’s the app you’re going to use in order to flash Android 4.3 XXUEMJ3 Jelly Bean test build.
  • Disable Samsung KIES software before starting the installation.
  • Disable all antivirus applications from running on your computer.
  • Backup all the files that are currently stored on your device. The Android 4.3 XXUEMJ3 test build flash process will remove all data from your Galaxy S4.
  • This is a guide for advanced users. Don’t attempt to use this tutorial in case you don’t know what you’re doing.
  • Do not blame us in case you brick the Galaxy S4 LTE or lose any data in the process.
  • Check the power left before your smartphone powers off. Make sure that there is at least 50% so that you’ll have enough time to complete the entire tutorial.
  • Enable USB Debugging from Developer Options menu.
    – if Developer Options doesn’t appear in Settings menu, then you should go to About Device menu, scroll down and tap seven times on the Build Number section. It will enable Developer Options for your Galaxy S4.
