I'm new to anrdoid. The Nexus 7 is my first such device. I've successfully unlocked, rooted, and installed clockwork mod recovery without any issues (thanks to the wonderful guides on this forum). I then installed Paranoid Android, and all was well. Booted and ran great. So then I installed the Motley kernel, now it goes to the Paranoid Android boot screen and goes no further. What did I do wrong, and what should I do from here?
