Ugh...just when I was starting to be completely content with my Rezound and it's awesome extended battery, I am stuck in a boot loop! When I power on the phone it get's to the main screen, shows an x for cell service, then recycles itself through the start-up procedure. I have pulled the battery, to no avail. Pulled the SIM and battery, same. Is there a way to fix this? Thanks for any help.
