  • Copy the downloaded SuperSU or Superuser zip file to the external SD card.
  • Power off the phone.
  • Boot into the stock recovery by pressing and holding “Volume Up, Home and Power” buttons at the same time.
  • Once you’re in the recovery, navigate to the “apply update from external storage” using volume keys.
  • Browse the copied zip file.
  • To begin the rooting select the SuperSU/SuperUser zip file using the power button.
  • Once installation has completed, go back the main menu.
  • To reboot the phone select “reboot system now” option.
  • Congratulation, you have just root Samsung Galaxy S2 GT I9100.
  • After the phone booted up, you can update the BusyBox by using “busybox installer app” on the Google Play store.

Now you can install the root permission require app on the Google Play store. When you are ruining a root access require application, SuperSU or SuperUser app will promote the root permission. You can grant the permission by tapping “Grant” button. Personally I recommend you to install SuperSU, it has more feature than SuperUser.
