Whether or not you've enjoyed the Android 4.1.1 Jelly Bean experience, our beloved developers have thought of ways to keep your flash-ready hands busy. Developed by the Criskelo Team, the Criskelo ROM is perfect for all you custom ROM lovers out there.

Criskelo version 19 looks very sleek. Not only does it run smoothly but is also very responsive. It comes with features such as being able to choose available themes, battery mods, toggles, and other modifications, thanks to Kitchen version 19. This ROM also comes with CWM Manager and many other goodies for your choosing.

Like all ROMs, Criskelo and Criskelo Kitchen are constantly being updated and modified to fix bugs and problems encountered by users. So far, there seems to be some issues with missing notification bars, as well as missing status bars for some of the available themes.
