Ice Cream Sandwich update AT&T Galaxy S2 SkyrocketA few days back we came across the very first Ice Cream Sandwich Android 4.0 (ICS) Firmware leak for AT&T Galaxy S2 Skyrocket. It was called as UCALC4. Now, we have come across another leak for AT&T Galaxy S2 Skyrocket. This new Ice Cream Sandwich firmware update leak comes from Rootzwiki and this has not been developed by them. They have got it from an unknown source.

But we will discuss the first method only over here.

Before you proceed, it would be important to make it clear that this is a leak and an unofficial update and thus there are a few bugs and issues which still remain to be solved. Thus before you move towards tutorial kindly go through the disclaimer. This is NOT an official firmware update from AT&T

Disclaimer: We are waiting for the official update, because these firmware leaks are not free of bugs and thus there may be some issues with your android handset, if you do not remain careful. However, you must perform the procedures at your own risk and should not be held responsible for anything that goes wrong with your Galaxy S2 Skyrocket while you upgrade your handset with the mentioned leaked firmware.
