Reinstallled the data, rebooted now all I have is a blac screen with hTC on it.
How can I do a factory reset (assume this is what I need to do?)

I read somewhere that when you restore home screens and system settings it causes the phone to crash. Turn the phone off, hold the home and power button until a phone icon comes up. Press the home and power button again and a menu should pop up, select reset, then select reboot. this time when you restore your data dont restore the home screens and system settings.Just selected everything.
