Install Official Android 4.1.2 Jelly Bean XXMC8 Firmware for the Samsung Galaxy Ace 2 I8160

The Samsung Galaxy Ace 2 has just received its official Android 4.1.2 Jelly Bean OTA Update. This guide is for those users who didn’t receive the OTA Update notification and wish to flash the XXMC8 firmware manually. Read the entire post and you will be able to install the latest Jelly Bean OS on your smartphone fast and easy.

This guide is for advanced Android users as you will need to use your Windows PC, connect the smartphone to it and then flash the XXMC8 Jelly Bean firmware update using ODIN application. The Android 4.1.2 Update brings the Google Now service, expandable notifications, buttery smooth UI, improved voice search, better keyboard, gesture-typing and multiple others.

In order to make sure that you successfully flash this new ROM for your Galaxy Ace 2, read first the preparation guidelines that I’ve listed below:

  • Use the guide only for the Samsung Galaxy Ace 2 model number I8160. Don’t try to flash this firmware on any other device with a different version number. Check this info under Settings> About phone. If the model number doesn’t correspond with your Galaxy Ace 2 then you should close this post.
  • Backup all your data files before getting to the ‘how-to’ part of this post. The tutorial might delete some data from your device.
  • Make sure that your computer has all the Galaxy Ace 2 USB drivers installed, as otherwise you won’t be able to flash the new update.
  • Enable the USB Debugging option from your phone’s Developer Options. Note that after the update is applied, you will need to re-enable the Developer Options section like this: Open Settings, then About Phone, scroll down to Build Number and tap this 7 times.
  • Make sure that your PC doesn’t have the Samsung KIES running on your computer.
  • Disable all the antivirus applications from running when you’re installing the new OTA update.
  • This guide is for advanced Android users and you shouldn’t use it in case you don’t know what you’re doing.
  • Don’t blame us in case something goes wrong and you lose data or you brick the phone in the process. Use the tutorial to ask for extra help.
  • Your phone’s battery should have enough power left before getting to the tutorial.

I think that these are all the steps that you had to go over before getting to the next part of this article and learn how to successfully update your device to a stock Android OS.
