Flash Official Android 4.2.2 XXUBMG8 OTA Update for Samsung Galaxy S2 Plus I9105P

Samsung has pushed out the official XXUBMG8 Android 4.2.2 OTA Update for the Galayx S2 Plus in Germany. This guide is destined for users from other countries that are still waiting for the official update notification to arrive. This is a guide that will restore warranty for devices that are currently rooted as you will simply need to flash it with Odin, but not that devices running custom ROMs will be completely wiped in the process.

Android 4.2.2 XXUBMG8 firmware update brings multiple improvements and tweaks that should enhance your Jelly Bean experience. More info about the added features can be found in this news article here. In order to correctly install this new update read the guidelines below:

  • Use this post only with the Samsung Galaxy S2 Plus international variant with the I9105P.
  • Do not attempt to flash the OTA Update zip file on the original Galaxy S2 I9100 device, as you will end up bricking.
  • If your phone is running stock Android 4.1.2 Jelly Bean then no data will be lost in the updating process, while the phones running custom ROMs will be wiped by the update.
  • If your device is rooted but running stock ROM, then the root access will be revoked but your data will remain intact.
  • Before starting the update you should make sure that your computer has the Samsung USB Drivers installed. If yours doesn’t then you can download them from here.
  • Backup some of your most important files before starting the update.
  • Disable the Samsung KIES program from running on your computer.
  • Disable any antivirus apps before starting the update. Such apps will interfere with the updating process and you won’t be able to install the XXUBMG8 Jelly Bean 4.2.2 ROM.
  • Odin is the program that you will use to update your device.
  • Enable USB debugging option from the Developer Options menu.
    > if Developer Options doesn’t appear in the Settings screen, then you need to enable it: open About Phone and then scroll down to Build Number, tap on this section 7 times.
  • Make sure that your Galaxy S2 Plus battery charge levels are over 50%, so that it won’t switch off while you’re flashing the update.
  • Read the entire post before starting the update and make sure not to skip any steps listed in the tutorial.
  • This is a tutorial that should be applied by advanced users who know how to use Odin app.
  • Do not blame us in case you brick the Galaxy S2 Plus nor in case any important data files are wiped in the process.
  • If you’re having problems with the updating process, then you should ask for more help in comments and we will make sure to offer you a viable solution that should allow you to complete the update.

These were all the preparation guidelines you had to go over before continuing to the next part of this post.

Use the comments section if you have any other questions about the Android 4.2.2 Jelly Bean OTA Update for Galaxy S2 Plus I9105P.

If you didn’t manage to update the device, then you should read the notes below and you might find a solution that will help you install all files and force your device to boot into normal mode.

NOTE 1: In case ODIN didn’t complete the update, it shows the ‘FAIL’ alert or it froze while installing the new files, then you should disconnect the device from computer. After that you should close ODIN, remove the phone’s battery and re-insert it after 5 seconds have passed. Now you have to repeat the entire tutorial once again and make sure not to skip any steps. For more help post a detailed comment at the end of this post.

NOTE 2: If ODIN says that the installation has passed, but the Galaxy S2 Plus gets stuck at the Samsung boot animation screen, then you will need to boot in Stock Recovery Mode and apply a factory reset. This process will remove all contents from your system partition, but it will force your device to boot the official Android 4.2.2 XXUBMG8 firmware in normal mode. Here’s how to do that:

  • Power off your smartphone completely.
  • Press and hold simultaneously Volume Up, Home and Power.
  • Release the buttons when the screen flickers and the Stock Recovery Mode appears.
    > if the recovery mode doesn’t boot then you should keep trying to repeat the ‘press and hold buttons’ action until it works.
  • Now, select ‘wipe data/ factory reset’ option.
  • Confirm.
  • Return to the main recovery screen when the factory reset is complete.
  • Select ‘reboot system now’.
  • Wait several minutes for the boot to complete and you will be done.
