IBTimes UK reminds its readers that it will not be held responsible for any damage to the device. Users are also advised to verify that their devices meet following requirements.

Pre-requisites

1) Install USB driver for Samsung Galaxy S3 to transfer files between the Android device and computer.

2) Enable USB Debugging Mode on the phone to connect the Android device with the computer and use the Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option and ensure the USB Debugging Mode is turned on.]

3) As the tutorial might wipe out all data of the phone, create a backup. If the device is having any custom recoveries such as CWM/TWRP already installed, then back up the data using the recovery.

4) The Galaxy S3 should have above 80 per cent of battery charge.

5) The phone should be factory unlocked.

6) The device will lose its manufacturer's warranty once it is rooted. But users can claim the warranty back by unrooting the device later. Click here for our step-by-step guide to unroot Samsung Galaxy S3 to stock official firmware and reclaim warranty.

7) The root package works only on the Samsung Galaxy S3 GT-I9300. As flashing this on any incorrect variant might brick the device, verify the model number of the Galaxy device by selecting Settings>> About device>> Model number.

Steps to root Samsung Galaxy S3 I9300 on Android 4.2.2 XXUFME3 Jelly Bean

Step-1: Download root package for Samsung Galaxy S3 to the computer

File name: CF-Root-SGS3-v6.4.zip

Step-2: Extract the downloaded root zip file

Step-3: Download Odin v1.85 which will help to root the Android 4.2.2 firmware on Galaxy S3. Extract the zip

Step-4: Switch off the Galaxy S3.

Now press the Power button again to continue to enter Download Mode

Step-5: Launch Odin on the computer

Step-6: Connect the Galaxy S3 to the computer using USB cable while it is in Download Mode. Wait until Odin detects the device. When the phone is connected successfully, the ID: COM box in Odin will turn yellow with the COM port number. Also, the successful connection will be indicated by an Added message in Odin. This step is likely to take some time

Note: If the Added message does not appear, then try another the USB port at the back of the computer. If that too does not work, then re-install USB driver.

Step-7: In Odin, click on PDA button and select the CF-Root-SGS3-v6.4.tar file

Step-8: Verify the Auto-Reboot and F.Reset Time checkboxes are selected in Odin. Do not select the Re-Partition option

Samsung Galaxy S3 running on Android 4.2.2 XXUFME3 Jelly Bean test firmware is now rooted successfully. Open the app drawer of the device and check for an app called Superuser from the list.

Also, to ensure the root method is installed and is working properly, verify with the Root Checker app from Google Play Store.
