I had a problem - it wouldn't flash. The RUU kept saying the phone wasn't connected, even though the rainbow screen said "USB" when I connected it. It said "serial" when it wasn't connected. Here's what I did to get it working again, one of these things or a combo did the trick:

-Follow instructions on page one of this thread to get phone into rainbow mode
-Disconnect, reconnect phone from PC
-Using WinRAR, extract the Sprint stock RUU (_HTC Touch Diamond (Sprint)_HTC Touch Diamond MR 2.00.651.7)
-From extract, run RomUpdateUtility.exe
-RUU went further, but gave another error.
-New option was to recover, select this
-RUU said to diconnect phone, reboot, reconnect, but don't do this!
-I disconnected and reconnected again but did not power off because it was already at the rainbow screen

Hopefully this will help someone else.

Thanks dude, you saved my phone!

I downloaded the sprint RUU from HTC website:
