Root A Samsung Galaxy S3

If you have installed Android 4.3 XXUGMK7 Official Firmware on your Samsung Galaxy S3 I9300, you may have noticed that you have lost your root access.  Installing official firmware on a Samsung device erases root access.
If you want to root your device again, or even root it for the first time, you can follow the guide on this post.

Prepare your device

  1. This guide is only for the Samsung Galaxy S3 I9300.
  2. Charge the device’s battery to at least over 60 percent to avoid running out of power.
  3. Enable your device’s USB debugging mode.
  4. Back up the EFS partition of your device.
  5. Back up your important contacts, SMS messages and call logs.

Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device.  Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers.  Be responsible and keep these in mind before you decide to proceed on your own responsibility.  In case a mishap occurs, we or the device manufacturers should never be held responsible.
