In order to correctly update your Samsung Galaxy S3 I9300 with the leaked Android 4.2.2 XXUFME2 Jelly Bean ROM. Here’s what you need to know:

  • use this tutorial only with the Samsung Galaxy S3 International variant model number I9300.
  • don’t try to update any other smartphone using this guide, as you will end up bricking it.
  • this is a stock firmware but not an official release by Samsung. It is a pre-release build of the final Android 4.2.2 JB OTA Update, but it will work just fine.
  • if your phone is rooted, then all the data stored on it will be wiped.
  • if the Galaxy S3 is rooted, then its warranty will be restored.
  • create a backup of all the files before installing the new XXUFME2 firmware update.
  • this update will install a stock Recovery.

  • enable USB Debugging from the Developer Options menu, under Settings. If this menu is not shown, then you will have to enable it going through Settings, then About Device and then you should press 7 times on the Build Number text.
  • disable Samsung KIES program in case you have it installed on your computer.
  • disable any antivirus applications before launching Odin, as these apps will interfere with the updating process and you might not complete the tutorial.
  • this is a guide for Android users who know what they’re doing, don’t try to flash the firmware in case you don’t know what you’re doing.
  • make sure to read the entire post and don’t skip any steps that I have listed below.
  • we cannot be held responsible in case you will lose data or you’ll brick the smartphone.

  8. Click ‘START’ to begin the installation of XXUFME2 Android 4.2.2 Jelly Bean. This process shouldn’t take longer than 5 minutes.

I hope that you’ve managed to successfully install this new firmware on your S3. If everything went according to plan, then you can close this tutorial and start testing the firmware.

Users who are eager to root the new XXUFME2 Firmware should return to our web site, as we will post a working guide soon.

If you had problems with the installation, then you should read the notes below.

NOTE 1: In case Odin showed errors, it froze or some other thing blocked the installation, then you have to close Odin, unplug the phone from PC. Power off the phone by removing its battery and then re-insert it after 5 seconds passed. Repeat the entire tutorial once again and make sure that you won’t skip any steps in the process.

NOTE 2: If ODIN says ‘PASS’, but the phone is unable to get past the Samsung boot animation screen, then you will need to perform a factory reset. This will delete all data from your computer, but it will force your device to boot with the new XXUFME2 Android 4.2.2 Jelly Bean firmware. Here’s how to do it:

  • power off the device, remove the battery and re-insert it after a few seconds.
  • boot the phone into Recovery mode by pressing Volume Up, Home and Power buttons at the same time. Release the buttons when the screen flickers and wait for the stock Recovery to appear.
  • select ‘wipe data/ factory reset’ option and confirm this process.
  • get back to the main recovery screen and select ‘reboot system now’.
  • wait for the device to boot into normal mode and enter your Google Account details when you’re asked by the new home screen of Jelly Bean 4.2.2 OS.
