This is for everyone else that may spend as many hours as I did trying to fix my HTC Diamond with Sprint service.

I have concluded that I must have flashed a GSM Rom, as I learned ppcgeeks is 99% CDMA, while XDA-developers is 85% GSM.

Diamond kept stalling in reboot then resetting on its own. Could not get past black screen with HTC Diamond writing. Tried hard reset, power+vol down+circle (enter key) hold all then push stylus in soft reset. Didn't work. Now here is your golden ticket that took me multiple hours of searching to find ~ Simply not pushing enter (circle button) hard enough to get to load back into boot screen. Pushed all buttons really hard - badabing - boot screen. Loaded juicy rom, working great.
Cheers!
