Does one know how update to jelly bean from 6.16.215?

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

Do I have to have root?

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?

Hi, I have the same 6.16.215, i also wanna update to JB, but i wanna know that this jellybean update supports GSM?? if it does then i'll update it but i'll have to go back to .211.

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.
