[4.4.4] OFFICIAL & UNOFFICIAL CM11 Builds

Rom: CM11
Android Version: 4.4.4 KitKat
*The I9100 exclusive "Unofficial" version of the rom is cross-compiled using latest Linaro & Sabermod Toolchains with Full O3 Optimizations and (in my opinion) is better than the Official version!

[UPDATED] BeanStalk Rom is here....FINALLY!

This rom needs no introduction for flash-o-holiks but for those of you who are new in this game, this is one of the best custom roms availble for U.S. variants of the Galaxy S2. With tons of customization options and under the hood goodies, this rom made its way to GT-I9100 with the release of KitKat. Here are a couple of screenshots straight from the OP. Have a look!
