Update Galaxy S2 Skyrocket I727 to CM10.1 Jelly Bean 4.2.2 Final-Build

We at DroidGator want to introduce owners of AT&T Samsung Galaxy S2 Skyrocket I727 a tutorial on how to install CM10.1 Android 4.2.2 Final-Build on it. Not too long ago we found about the existence of this tool and we thought it went very well with this sort of device. So we chose it for the guide, and hope you will enjoy it, too.

Everyone, including us, agree on the fact that the CM10.1 will not make your handset perform in a crappy way. On the contrary, this tool will bring stability and an overall impressive performance.


The guide we recently put together does not deliver the kind of steps which are impossible to follow. Or so we hope. Our readers will now be welcomed with a set of requirements that go like this: charge the battery inside the phone, turn on USB Debugging and make backups using this guide. Don’t worry of the warranty goes away after you are done with the tutorial: you can always regain control of it by installing official firmware on the Galaxy S2 Skyrocket SGH-I727.Galaxy-S2-Skyrocket-I727
