Since there is so much variety in Android phones, there is no single rooting method that will work for every phone or version of Android. To get started, you will need to download the appropriate rooting software for your phone model (most of these are for Windows only), enable USB debugging on the phone, and configure your USB drivers on your computer. Don’t forget to backup your data before rooting!

Warnings

  • Make sure the software you are using matches the model and version of the phone you are trying to root. A mismatch can cause the root to fail and potentially brick your phone.
  • Unlocking the bootloader and rooting the phone may void your warranty.
