I believe i am using the TeamWin recovery. (i got it from here: Download: Nexus 10 “mantaray” Android 4.2.2 JDQ39 Update – Droid Life
and for rooting, I followed these instructions: http://forum.xda-developers.com/showthread.php?t=2015467
Hope that you can help me with this info. I even tried updating from the stock recovery and it says the package file is invalid.
I might just unroot, factory reset, update, then re root.
