I have a non-rooted EVO with all the latest updates and lately it will randomly go into a reboot loop. The only way I've been able to stop this loop is immediately put it in airplane mode, that is when it gets as far as the main screen. Usually it doesn't even get to the 4G animation before crashing again. Is there a fix for this? Or is this a hardware issue? I have not done a hard reset yet or anything.
