Try these 2 things:

1) if you're flashing from windows 7, try using XP

2) Flash just a different radio, without a ROM, see if the progress bar goes up.

3) Try another USB cable. charge your phone to 100% and try again.

4) refrigerate your phone for 30 minutes then try again (don't ask me why, but I have had this solve some problems)
