How to root Galaxy Ace 3 S7275R using RootGenius for Android:

  1. Download the RootGenius exe from here.
  2. When the app is downloaded you should launch it on your PC.
  3. Take the USB cable and connect the Galaxy Ace 3 to your computer.
    - wait until the RootGenius app detects the phone and then you can continue to the next step.
    - if the device isn't recognized, then you will have to repeat the entire process once again.
  4. Hit the 'Root Now' button when you're ready to start the rooting process.
  5. RootGenius will begin the rooting process. It will flash the KingUser app on your smartphone.

  • boot it in Recovery Mode by pressing at the same time Volume Up, Home and Power.
  • when the Recovery Mode menu appears you will need to select 'wipe data/ factory reset.
  • confirm process.
  • reboot your phone after the factory reset is complete.

This will remove all the data from system partition...? I would say that from user partition. It would be better not to erase system mtdblock ;)
