You need to go back to 211, I did that using Matt's utility, I then side-loaded JB and alll is golden.

Running 6.16.215 from the recovery method. Is Matt's Utility only from root users? From what I can tell it is. Is there a way to go back to 6.16.211 with a non-rooted device?

okay i used the Matt's utility and went back to stock ics .211, then updated my phone to JB with recovery method, its working good.
will test the battery life too, i hope it gets better cause ics on my phone was no good, my battery drained alot faster before, lets see that happens now.
