Samsung Galaxy S3 GT-I9300

An Android 4.3 update was released by Samsung for their Galaxy S3 recently.  This update contains some bug fixes and makes some performance enhancements and core UI changes.  It also adds Galaxy Gear support and some other features.

In this post we are going to show you how you can install a Custom Recover and then root a Galaxy S3 after the Android 4.3 Jelly Bean update.

Prepare your phone:

  1. This guide will only work with a Galaxy Note S III GT-I9300. Check your device model by going to Settings>General>About Device
  2. Charge your Samsung Galaxy S3 device so that it has 60 percent of its battery life. This is to prevent it from running out of power before the process completes.
  3. Have your OEM data cable to connect your device and your PC.
  4. Back up SMS messages, contacts, call logs, and important media files.
  5. Enable USB debugging mode by going to Settings>General>Developer Options.

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
