This news of custom ROM comes straight from the XDA-Developers – one of the best forums for Android enthusiasts – in the form of a thread posted under the Galaxy S II (S2) sub-forum.

Before you start to get into flashing the ROM on your Galaxy S II, keep in mind that it is highly experimental build with loads of bugs and stability issues. That’s not for daily use and advised to stay away from this unless you’re an Android hacker or developers with advanced knowledge of rooting device, flashing and restoring back in case something wrong happens.

First of all your device must be rooted and ClockworkMod Recovery flashed. Apart this, the developer has asked interested enthusiasts to be running on an Ice Cream Sandwich-based bootloader. You can follow our guide on how to root Galaxy S II and how to flash ClockworkMod Recovery but you will have to search for an ICS-based bootloader on your own, and then flash it using ODIN. Once you’ve met all pre-requisites, follow the full guide after the caution!
