Many Android devices have received the latest Android 4.2.1 update via custom ROM Jelly Bean firmware, while a select few can now access improved Jelly Bean features with due credit to the release of CyanogenMod 10.1 (CM10.1) ROM.
The CM10.1 ROM reportedly ports the best customisable interface of all available custom ROM Jelly Bean firmware. The ROM includes a plethora of exciting features that are unavailable in the stock ROM.
Some of the notable Android 4.2.1 Jelly Bean features include multi-user support, gesture typing, new quick settings option, lock-screen widget, new camera app, photo sphere, improved Google Now, new daydream feature and miracast display.
As the CM10.1 ROM is an unofficial build which is still under development, it may harbour a few untested bugs or broken features. On the brighter side, all such issues are expected to be fixed in the upcoming updates. The instructions below are for installation on the Galaxy Note 2 N7100.
