I started using PA on my Galaxy Nexus with a fresh install of 4.0 Beta 6 about 4 weeks ago (unlocked and rooted via nexus root toolkit, recovery is teamwin).
Since then, I installed every update through Paranoid OTA, so I am on current 20140318 now with GAPPS stock 20140318.
Everything was great.
Suddenly, a few hours ago, the phone started rebooting again and again until I decided to take out the battery.
Since then, it hangs during boot at the PA logo.
I tried reinstalling pa_maguro-4.0-BETA6-20140217.zip and pa_gapps-stock-4.4.2-20140217-signed.zip through recovery (after backup of course), but this changed nothing.
Fun thing is... I am moving to a new flat tomorrow and really need my phone to organize things.
So if anybody has an idea what I can look at or how this may be fixed, I would really appreciate it.
Edit: wiping cache and dalvik cache did not help...
