CM11 ROM + OnePlus One Conversion Kit for Galaxy S2!


For those of you looking to try out the new OnePlus One smartphone, did you know you can install CM11 ROM and our HighOnAndroid OnePlus One conversion kit on your Galaxy S2?

This combination essentially turns your Galaxy S2 into OnePlus One, you will get nearly all of OnePlus One software features like OnePlus One lockscreen, Hexo theme, OnePlus One camera, Voice Recording app, and Screencast app (allows you to record voice while recording screen but having some trouble getting working on SGH-T989, works fine on GT-i9100 and SGH-i777).

For GT-i9100 and SGH-i777 users, you will benefit from having a stable CM11 ROM Snapshot “M9”, which is very stable and fast.  (Everything should be working flawless out of the box.)

For T-Mobile SGH-T989 users, you won’t be able to get a stable Snapshot version (as CyanogenMod team has stopped releasing snapshots) but you can still get pretty good performance with unofficial version.

Overall, this is a fun way to spend your week(end) or free time and try out what’s on the OnePlus One so definitely give this combo a go this week(end) and do let me know what you think!
