Go here and follow steps 1-9 on post #84. HOWEVER, instead of downloading Clockwork 18.104.22.168, use this link for Clockwork 22.214.171.124.
Use this link to download the 2.2.2 Update, since it is no longer available to download on the HTC site.
After completing steps 1-9, use post #83 to install your recovery. I ignored the first paragraph of that post, though. Make sure USB debugging is on!
After your recovery is installed, simply restore your nandroid and boot!
