Accidentally Installed Official Froyo 2.2 Update on Rooted Incredible

I am a Verizon customer and completely didn't stop to think that I had rooted my HTC Incredible when I manually applied the Official Froyo 2.2 update today. As a result my phone will boot up with Froyo but once to the initial home screen the white HTC screen loads and a loading indicator appears. This will remain on this screen for some time before throwing a ForceClose and ultimately causing the phone to restart. It will keep this cycle going until I stop it.

I have tried all the different angles out there for unrooting this device. Everything from proper formatting of the SD card to utilizing the right downgrade ROMs. I have covered every angle I could find by searching in the last 5 hours. I really need to recover this ASAP as I use this phone for work / business purposes.

I am running the Unrevoked Recovery ROM. I have the files to also turn off signature checking but right before I was going to try that (as the phone does not read the downgrade zip files) I zero'd my SD card out and then recreated the partition table as well as formatted it to be fat32 (via GParted).

Need Help Please!

 

I really mean it when I say I exhausted all posted solutions (even this one) but thanks for the suggestion. I have given up and will soon have it replaced.
