Though there are several devices relesing with Android 4.2 Jellybean operating systems now a days, few Samsung smartphones like Galaxy S3 or Note 2 are still running on Android 4.1. There were rumours to get 4.2 updates on these phones but it kept cancelling again and again. Now finally there is a news that Samsung has dropped the idea of releasing 4.2 Jellybean update and they have started working on Android 4.3 (which launched last week). But this will surely take few more months to reach the device.

So as of now if you are fed up with the same 4.1 user interface and need some change, you can consider Custom ROMs to get Jellybean 4.2 os on your phone. The one i am talking about here is Avatar ROM. The platform for avatar ROM is CM10.1. It will be similar to CM10.1 and features provided in this ROM will be almost same like of CM10.1. If you wish to get this update on to your phone then all you have to carry out some procedures and take care of few steps.

  • First of all start with taking entire backup of the device. So that if any thing goes wrong you will be able to restore the data later.

  • Backup your contacts, messages, app data, etc safely on SD Card or on your computer.

  • Charge your battery fully or atleast 70% as this procedure will take some time and your phone should not switch-off in between.

  • Enable USB debugging mode of your phone from settings on to your phone.

  • ClockworkMod Recovery should be installed on your phone to carry out the installation task.

  • Download Avatar ROM for Samsung Galaxy SIII

  • Download Gapps for S3

  • Copy both of these files on your phone's SD Card.

  • Now turn off the phone and boot into recovery by holding down Volume up, volume down and power button

  • Using volume keys scroll down and select Wipe data/factory reset

  • Now clear cache memory, tap Advanced option and wipe Salvik cache.

  • Now perform Nandrop backup of your accessible ROM. Select “Backup and Restore” and then select “Backup” again.

  • Once done, go back to recovery home screen and select “install from SD Card”.

  • Select “install zip” and browse where you have saved Avatar ROM. Select the same and install.

  • Wait for some time and let the installation get completed.

  • Repeat the same procedure to install Google apps by selecting “Choose Zip from SD-card” and select “” and start installation process.

  • Once done, go to recovery home screen and select 'Reboot the System'

Phone will take time to reboot as this is the first boot after installing the new rom. Once done, do all settings and emjoy new Android 4.2.2 JellyBean OS on yoru Galaxy S3.
