okay my phone is an HTC 5800. when ever i turn it on it starts up fine, then it goes to the main screen like every cell phone. once that happens it freezes? Why!? how do i fix it? i cant press any buttons! it stays on with the back light and nothing works! i went to bell and the guy was like oh it needs an update. plug it in on the com. and go to this site. the website wont let me update it unless my phone works! What do i do! i really like this phone! and my warranty is done! is there anyway i can " Factory Reset " it ? PLEASE HELP!
