http://androidforums.com – A friend of mines phone was stuck on the HTC screen every time she tried to reboot her phone. So we powered it down and brought it back up with the volume button down+power and did a factory reset. The phone came up with the normal screen "verizon loading blah blah" and once that finished and it rebooted it never came back up. Now it doesn't respond to any sort of reboot attempts. have any of you experienced this? The phone was stock and not rooted. (General)
