How to Root Samsung Galaxy S3

This tutorial will guide you through the steps to root Galaxy S3. This tutorial will help you to setup ClockworkMod recovery to the recovery partition and superuser file. Rooting Samsung Galaxy S3 is safer than S2, because in S II the recovery partition was a part of the kernel. There was high-risk of phone brick. Thanks to Samsung, they’ve followed Nexus’ way and made recovery partition separate from kernel. Thus, making it safer to root.

Warning: Even if it’s safer than S2, there are chances that your phone might brick. Root your device at your own risk.
