Earlier this morning, DesignGear and the folks over at RoozWiki leaked the first ever Ice Cream Sandwich firmware for the AT&T’s Samsung Galaxy S II Skyrocket 4G (SGH-I727). Like the Ice Cream Sandwich update for the Galaxy S II, the leaked ICS firmware for the Skyrocket is also plastered with TouchWIZ so as to spoil all the visual goodies offered by Ice Cream Sandwich.

The firmware has no bugs, and everything works like a charm. According to the build.prop, the firmware has a build date of 14th March and points of it being the final official ICS release for the Skyrocket.

If any if the Skyrocket 4G owners are interested in installing this leaked ICS firmware on their handset, follow the guide below -:

P.S. – Your handset will be wiped clean of all data, including your contacts, sms and installed apps, so please make a backup before proceeding with the steps below. 

Step 1: Download the 600MB+ firmware file from here. It is a one-click exe file, which contains ODIN along with the required firmware packages. After downloading it, double click the exe and wait for ODIN to start.

Step 2: When ODIN starts, switch off your Skyrocket 4G and re-insert the battery. Now, boot your handset into Download mode by pressing the Volume Up + Volume Down simultaneously and connecting it to your PC or Laptop. Keep the buttons pressed while connecting your phone to your PC, otherwise the phone will not boot into Download mode.

Step 3: Once your phone boots into Download mode, and is detected by ODIN, simply click on the Start button in ODIN and wait for it to flash the firmware.

Once the firmware is flashed, your phone will automatically restart. Keep in mind that the first boot can take some time.
