I'm on 4.1.1 stock rooted. I've received the 4.2.2 update and tried to install it a few times. I have the stock recovery and it begins to install, but gets about halfway through and then stops.

I've used Android Root Toolkit to return to a stock recovery. I did have a different kernel, but I reflashed the stock one that I extracted from google factory images ().

Here is text from the end of the last recovery log. Any ideas on what I should do?
