You can read all the info listed in this post and you’ll learn how to successfully flash all the required files in order to get this new ROM on your Samsung Galaxy S2 I9100G International version with TI OMAP CPU.

If you want to learn more about this new custom ROM and the work that AOKP team put into releasing it, then you should use this post here.

In order to make sure that you correctly install this new AOKP rom for your device, you will first need to take a look at the preparation guide below:

  • Use this tutorial only with the International variant of the Samsung Galaxy S2 model number I9100G. This is the device that runs on TI OMAP processor and not the Exynos model.
  • Do not attempt to flash the files you find here on any other Android device as you will brick it.
  • The I9100G Galaxy S2 device you’re about to update should be factory unlocked, fully rooted and running a custom Recovery image like TWRP or CWM.
  • This tutorial contains instructions for both TWRP and CWM Recovery modes and how to install the AOKP M2 using their features.
  • Before installing the ROM you will have to create a NANDROID backup of your current ROM, so that you’ll be prepared in case the phone gets bricked or you lose any important data in the process.
  • Also, the tutorial will ask you to apply ‘factory reset’ before installing the ROM. That is why you should know that the contents stored on the system partition partition will be lost. This includes installed apps data, SMS, Call logs info and other similar data.
  • If you want to save installed apps data, then you can use the Google Play Store and look for a working tool that can help you backup entire applications.
  • To backup SMS, APN Internet Settings or Call Logs info use the following apps for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore. Root access will be needed for some of these apps.
  • Make sure to sync your Contacts info with your Gmail account before starting the updating process.
  • enable USB Debugging from Developer Options menu.
  • Read all instructions and don’t skip any steps listed below, as that will result in a failed attempt of updating your device.
  • This is a tutorial that you can complete in under 5 minutes, but it is still recommended to be applied by an advanced user.
  • Don’t blame us in case you lose important data in the process or your brick your Galaxy S2 I9100G.
  • If you have any problems installing the update, then you should ask for more help in comments.
  • After the ROM is installed you should know that you can keep on updating it using the AOKP Updater that’s listed under the ‘About phone’ menu. Check periodically for updates in order to keep your device running the latest AOKP builds.

These were the guidelines you had to go over before starting the installation of AOKP M2 ROM. Make sure that you don’t skip any steps listed below.
