Android Open Kang Project (AOKP) posted the first Android 4.4.2 KitKat based nightlies for a number of popular Smartphones and a few tablets as well. AOKP is a custom ROM that gives the users full control over the ROM, allowing them to modify more aspects than any other custom ROM.

Nightly builds usually contain a lot of bugs. Just a warning, before you dive right in. AOKP would rather you use the stable Android 4.3 build than using an unstable ROM and then crying about it. If you are still ready to go ahead, here's where you can download the ROMs from.
