Possibly may seem like a stupid question, but did you protect root with Voodoo OTA Rootkeeper and then Temp UnRoot first?
If you did, there may be an issue with one of the apps you froze where it didn't properly "un-freeze". I am assuming you didn't "delete" any stock apps, right?
If you can't find the problem, your only option may be to restore to Factory default state. If so, you will want to use the

Good luck! :biggrin:
