Hi, Since the Official KitKat Update for Nexus 7 Is Released, I Have a Question.

Right now my nex 7 asked me to update to KitKat android v4.4.

As i tapped update, my device was rebooted to recovery and shows me an "error installing update" message. I should say, that i have a TWRP, custom motley kernel and root access. Is it plausible for me to update my tablet to android 4.4 and will it keep all features i described (i mean kernel and root)?

p.s. Sorry for my English :)
