After the great success of Galaxy S, Samsung decided to create a modified version called Galaxy S Advance running Android 2.3 Gingerbread and upgradable to Android 4.1 Jelly Bean. Samsung hasn't confirmed yet any possibility for Android 4.2 Jelly Bean being developed for Galaxy S Advance, but owners can get the latest Jelly Bean version through CyanogenMod 10.1.

CyanogenMod 10.1 provided Galaxy S Advance with Android 4.2.1 Jelly Bean, system tweaking and much customisation option.

Requirements:

1. The device must be rooted to flash this custom ROM

2. Battery level should be at least 70 per cent to avoid power interruption.

3. Create a backup of all your personal information, settings and data files on your device.

4. Install a custom recovery such as ClockworkMod or TWRP recovery on your device.

5. Enable USB debugging on your device.

6. Install the necessary USB drivers to your computer.

7. Download the CyanogenMod 10.1 for Galaxy S Advance and the Google Apps package.
