Been using my iPhone 4 for the past few weeks and finally broke the Evo back out to compare it for a few weeks. When I turned it on I got the notice for update so I did it thinking maybe it would help with the random reboot problem I had been having. Well after the update it sticks at the white HTC screen. I have tried all the basic fixes, held down volume/power, clear storage, recovery. When I clear storage it reboots and hangs at white screen again, if I do recovery I get a picture of a phone with a red triangle with a ! in it. Any way to re-flash the phone or something to get it working? I assume If i can get something on the little SD card but how do I do that when the phone won't work? I'd really like to not have to deal with getting it replaced. Thanks!
