[htc_d]

Hello everybody
Tried everything but still no luck. I would like to thank every one who tried to help me and others in this thread.
I have an idea:
I would like to return the phone to sprint for service since its still under warranty
But as you all know I have different roms on my 2 htc diamonds, want to flash it back to stock sprint rom, didnt know how to do it without being able to active sync, but here the idea:
what if I just download sprint rom into my internal storage and then try to open it?
But I think I will need a cab file?!
Can someone confirm this?
Thanks a lot
