How To Root Samsung Galaxy S2 at &t ICS UPDATE


How To Root Samsung Galaxy S2 at &t ICS



Samsung just recently rolled out to the Samsung Galaxy S2 GT-I9100 a new Ice Cream Sandwich update known to the community as the XWLPD build. For those of you who have just flashed the recent firmware, you may already know that flashing official ROMs such as the XWLPD firmware will mean losing your root privileges.
Luckily for Galaxy S2 owners, XDA Developers member Chainfire has already made an exploit that will allow you to root your phone, as well as install ClockworkMod Recovery using the CF-Root Kernel. The kernel is fully stock and is primarily based on the original firmware, with some added features. The CF-Root Kernel has root access, BusyBox 1.16.2, and ClockworkMod Recovery.
Learn more about rooting and installing this modified kernel by checking our step-by-step guide below.
