Well, that makes sense that the 2.2 from the forum link did not flash as I don't think that will load with the 2.XX bootloader version. You also can't flash that ROM with Vista. But I guess you would have to go from your own memory on how you upgraded the phone. Do you ever remember upgrading to the 3.3 ROM? What AKU was that HTC ROM? I've been googling for a way to convert the PIM.vol into some usable format but haven't seen anything. You are putting the saved copy in the root directory of the phone, right? I suppose you might try going the PIMbackup route and, even though the file appears to be nonfunctional, create a backup if it will let you, and then see if it restores it. I dunno.
