Procedure to Update Galaxy S3 with Jellybean 4.2.2 Firmware:
- Download Jellybean 4.2.2 Firmware Package and Google Apps Package from here to your computer. Connect your phone to the computer with the help of original USB cable and place the zip file in your device. Make sure that you are placing the zip file in the external sd card and not in the phone memory.
- Download the “ROM Manager” app from the Google PLAY Store and once the same is installed, select the option of “Flash Clock Work Mod Recovery” and select “Enter device in recovery mode” from appropriate option.
- In recovery mode, select “install zip from external sd card” to select the zip file which you have placed in the phone along with the Google Apps. Once selected, confirm the same and click on “Start” to start the process of firmware update.
- Once the firmware is updated successfully, you will see the message as “install from zip card complete”, now select “go back” option and select the option of reboot system now for rebooting the device in the normal mode. Please note that it will take more time than expected for rebooting the device as its the first time the device is booting after the firmware update.
Note: Just in a rare case if the device is not updated and it gets into the boot loop mode, you need to again clear the cache from the recovery mode and retry the whole process from the start.
We are here for you, at any point of time if you face any issues in the process of firmware update, feel free to leave a comment either below or in our facebook / Google+ Page as we will try our level best to revert with the same.
