No problem. I would try the RUU that you run from your pc rather than the PC36IMG file that Mike is referring to. It seems that many have more luck with it.
When I tried that moments ago, everything seemed to be working fine... it said, updating image version 3.29.651.5 to 3.70.651.1. I then rebooted the phone, returning to an "HTC" screen. The PC screen showed "Waiting for bootloader" for about 2 min - then errored out saying it couldn't connect to the phone. Seconds later, the phone rebooted, and came back up to the original MIUI.
Seems like I'm striking out on all attempts.
