Mine bricked after the update. First, all the apps started crashing (Words With Friends, OKCupid, etc). Then the phone got stuck at the boot screen with the letters HTC and would not respond to power button and since there's no battery to pull out, no way to shut it off. I got a replacement phone and the same update showed up and I cancelled it. Any ideas what may have caused it? Anything I can do to prevent this from happening again? I have an Unlocked HTC A9 on AT&T.
