Android 4.0.4 for Galaxy S2 i9100: Flash the F1 GalaxyNexus ROM
Google recently released the Android 4.0.4 sources (along with the 4.0.4 update for the Galaxy Nexus), which brought along performance and stability improvements. Recognized XDA developer Faryaab has built an Ice Cream Sandwich Android 4.0.4 ROM for the Samsung Galaxy S2 that gives you a stock Android experience as found on the Nexus, without Samsung’s custom TouchWiz UI to mess things up (for those who don’t like it).
The ROM also takes sources from Cyanogenmod, so expect the same bugs and issues as found in CM9 to be present in this ROM. The developer has said that he will update the ROM regularly as and when CM9 development moves ahead, so keep an eye on this one.
Read on to find out how you can install the F1 GalaxyNexus ROM on your Galaxy S2.
This ROM and the guide below are compatible only and only with the Samsung Galaxy S2, model number i9100. It’s not compatible with any other device. Check your device model in Settings » About phone.
