If you ever randomly bootloop (and its not something like cpu related OC or whatever), wipe dalvik and see if it fixes it. 90% of the time it does.
Judging by your edit you were messing around with something system related. Just full wipe and restore your apps.
Nah i usually dont tamper with shyt. But i shouldnt have said bootloops:
I turned on my phone and it didnt boot at all. Did a davlik wipe and that didnt fix it either.
Reflashed completely and my apps wouldnt download..had to reflash it again..looks like its working now.
