As a big Christmas present to the custom ROMmers out there, Paranoid Android and AOKP have released their first Kit Kat builds for supported devices. Neither ROM has all the features we’ve grown to love just yet, but they are still very much at early stages yet.
Paranoid Android doesn’t have the Hybrid Engine, HALO, or PIE just yet, but they are expected to be added in shortly down the track. Devices currently supported are Nexus 4, Nexus 5, Nexus 7 (2012 and 2013), Nexus 10, and Galaxy Nexus. The Oppo Find 5 and N1 will be supported in the near future.
AOKP, doesn’t yet have Android 4.4 builds available on all supported devices, but Team Kang are adding more all the time. So far, nightly builds are available for Nexus 5, Nexus 4, Nexus 10, Nexus 7 (2013), Galaxy Nexus, Galaxy S III, Galaxy S 4, Galaxy Note 2, HTC One, Xperia Z and ZL, Xperia T and Xperia V.
These ROMs are both pretty experimental at this stage, and unless you absolutely must have the very latest ROM, it’s probably best to stick with what you’ve already got. Remember as well to make a backup of anything you don’t want to lose – you never know when something will go wrong.
