How to Update Galaxy S3 I9300 to Android 4.2.2 Jelly Bean with Vanilla RootBox ROM
- Connect the phone to your computer with original USB cable.
- Without extracting, copy the downloaded RootBox ROM and Google Apps zip files to the root folder on your phone's SD card.
- Disconnect the device's USB cable from computer and then switch off the phone.
- Now, boot the device into ClockworkMod (CWM) recovery by pressing and holding Volume Up, Power and Home buttons together until the Samsung logo appears on screen. Then release all three buttons for half a second and hold them again. Now, the CWM recovery screen should appear. NOTE: Use Volume keys to navigate between options and Power key to select an option in recovery.
- Take a Nandroid backup of the current ROM, so that it can be restored later if the new ROM fails to work or you want to return to the original ROM. To take a backup, choose Backup and Restore, and then hit Backup again on next screen. Return to main recovery menu once backup is done.
- Now, perform a full data wipe process. To do so, click Wipe Data/Factory Reset and choose Yes on next screen to confirm. Wait for a few minutes until the data wipe process completes. Then return to CWM recovery main menu. Choose Wipe Cache Partition and after the wipe process completes, tap on Wipe Dalvik Cache under advance option.
- Choose Install zip from SD card, then click Choose zip from SD card. Now, browse to the Vanilla RootBox v3.8 ROM ZIP file that you copied earlier in Step 2 and select it by tapping Power button. Confirm the ROM installation on the next screen by choosing Yes and the installation will begin.
- After the ROM installation is complete, repeat the step 7 but choose the gapps-jb-20121212-signed.zip file instead of ROM zip to install Google apps.
- Once both the ROM and Google Apps are installed, return to the main recovery menu and tap Reboot System Now to reboot the phone into Android 4.2.2 Vanilla RootBox v3.8 ROM. The first boot may be time-consuming. So, leave it alone.
- Restoring to Previous ROM: To return to your previous ROM, boot into Recovery, choose Backup and Restore then restore your original ROM by choosing it from the list.
