Finally stopped kicking this can down the road. The 4.2.1 update wouldnt work for me, presumably because I rooted using the Toolkit back when it had the bad image from Google. I updated the Toolkit today and reflashed using Google's supplied image. Now, when I go to settings and check for updates, the normal 4.2.1 update screen comes up and I click "restart and install" it doesnt work. It says "rebooting to install" with a countdown, but never does. It stays on that screen forever if I keep the screen awake. If I let the screen turn off, when I unlock the screen it's back at "reboot and install" button like nothing happened. What should I do?
