Last month, after a long time all Galaxy S3 GT I9300 owners finally got the opportunity to enjoy the Official Jellybean 4.2.2 XXUFME7 Firmware. Of course updating to the latest official firmware sacrificed root access. So those of you how want to regain root access have to root their Galaxy S3 I9300. Before proceeding to the next steps double-check your phone version by going to Settings -> About phone -> Firmware Version. Keep in mind that this tutorial is only for the I9300 version of Galaxy S3, so other variants of this phone are not supported.
NOTE! We are not responsible for anything done to your phone. Please follow the steps mentioned in this tutorial very carefully otherwise you’ll probably brick your device. Bear in mind that rooting will void your Warranty until you unroot your device.
Prerequisite Steps:
- As this process will likely corrupt or erase some information, backup all your data (Images, Songs, Contacts, Messages, etc.) manually. Don’t use Samsung’s KIES.
- Enable USB debugging on your device. For 4.2.2 go to Settings > Applications > Development > USB debugging.
- Install USB driver (link) for Samsung Galaxy S3 I9300 to be able to connect the device with the computer.
- Charge your phone’s battery before proceeding. It shouldn’t be lower than 60%.
- Make sure your Galaxy S3 is factory unlocked.
Rooting Process:
- Download CF-Root v6.4 and extract it to a convenient folder.
- Download and extract Odin v3.07.
- Turn off your handset and wait like 5-6 seconds for the vibration confirming it’s completely shut down then, boot the phone into Download Mode by holding Volume Down, Home and Power buttons all together until Android appears on the screen. Then press the Power button again to enter Download Mode.
- From the earlier extracted folder, run Odin.exe as Administrator and connect your phone to computer via USB. ID:COM box should now turn yellow. A successful connection should also be indicated by an “Added” message in Odin. This step might take some time.
- Once your phone is successful connected, press the PDA button in Odin and pick the root file extracted during the first step.
- Make sure the Auto-Reboot and F.Reset Time option are checked. Do NOT touch any other checkbox.
- Click on Start button in Odin to start installation process. It will take up to 6 minutes, so please be patient.
- Eventually, you will get a “Pass!” notification in the ID:COM box and your device will reboot automatically.
- Congratulations! Your Samsung Galaxy S3 has now been rooted. If you want to check your root status, go ahead and download Root Checker application on your device.
