I don't know that phone, so can't really say. Your best bet would be to ask in that device's forum here (you'll find it in the Android Phones section of AF).
Having said that, the only bit of it that's obviously Desire-specific is the RUU, where obviously you'd need to use an RUU for the Incredible rather than a Desire one. If you are S-Off you can certainly try the two fastboot commands, which I think should work (or if you are using 4Ext recovery - if that exists for that phone - it has a "fix usb brick" feature built in).
