Note: please post follow-ups on the bottom of your message; it keeps 
things in chronological order.

I had a phone do the same thing, and after about 100 reboots it 
"magically" worked.  I have no idea why; the person who was working 
on it simply gave up and let it sit on his desk and cycle for (1? 3? 
5? days) and he came back and it was working.

Try loading one of the "other" images first, perhaps one of the 
smaller ones (3.2.2) and see if that solves any problems.
