Users of the Sprint variant of the Samsung Galaxy S3 (SPH-L710) can now upgrade their devices to the new Android 4.2.2 Jelly Bean, thanks to the new Slim Bean Build 3 custom firmware, based on the latest Android version.


Apart from bringing the updated Android 4.2.2 Jelly Bean to the Sprint Galaxy S3, the Slim Bean Build 3 custom ROM also comes with several customization options that cannot be found in the stock ROM. However, as an Android Jinn report pointed out, Slim Bean Build 3 is still under development phase and may hold some bugs. But the best thing is that all of these issues will be resolved as development progresses.

The Slim Bean custom ROM is known for low file size and fast speedy nature. On the other hand, the Sprint Galaxy S3 also sports “satisfactory hardware configuration and have enough power to run this latest build smoothly,” the report added.

Below is a tutorial showing how to install Android 4.2.2 Jelly Bean on Sprint Samsung Galaxy S3 (SPH-L710) using Slim Bean Build 3 custom ROM. Before going ahead, take a look at certain aspects that you need to be aware of:
