Do you really have to format the SD?
100% yes. You can try the RUU method at the bottom of the OP if you don't want to use the SD card route.

Do you really have to format the SD?
I have now tried reflash.exe on two different Windows XP computers. So far I have not been able to root from either of these PC's. I did a search on Clockwork and got Clockworkmod but it sounds like you must be rooted to install that. If I can use Clockworkmod where can I download it from? I just want a simple fix to root, remove S-On and unroot. Is there any other way to root without using the reflash.exe whick I can't get to work? According to my Device Manager the USB drivers are loaded and showing but reflash will not find my phone and do the root. Thanks for any help.
Update: The files linked below have been updated to include stock 2.2 plus the 'November OTA' contents.
There have already been several requests for information on how to downgrade back to the official 2.2. The following process will remove root. Whether you need to return a phone or you just want to clean the slate and go back to stock, here is how to get there:
Note: Your SD card MUST be formatted to FAT32 before proceeding. The file will not be recognized otherwise. If you have yet to format, remember that formatting wipes the card. Be sure to copy/move your SD contents to a safe place (PC desktop) and replace after the formatting process. I will not go into the procedure in this thread as it is easily found with a Google search.
1.) Need to return a phone and currently have S-Off? (aka Unrevoked Forever) If so, please visit public:forever [RootWiki] where you can download the latest S-On tool and the process to load to your phone. If you want to keep S-Off and just return to the official 2.2, skip to step 2.
2.) Download the 2.2 PB31IMG.zip (extracted from the official 2.2 RUU)
Mirror 1 (Credit and thanks to Doug Piston for hosting)
Mirror 2
Once downloaded, rename the file to PB31IMG
Note the file size (172 MB) and the MD5 (31BB1611A0FA8197D447C0438426717E) to ensure a successful download and file integrity. If you have questions about how to verify MD5, please see post #2 of this thread.
3.) Attach phone to PC with USB debugging on and in disk drive mode.
4.) Access the SD storage and drag the PB31IMG zip file (still fully zipped) from the desktop onto the root of the SD card (any open area, do not place into a folder).
5.) Swipe down notification bar on phone and change to charge only.
6.) Unplug phone from PC and turn off phone.
7.) Hold volume down while pressing power button to enter hboot.
8.) PB31IMG.zip should be automatically recognized in hboot. Press volume up to continue with update. Do NOT interrupt.
9.) When finished, reboot to stock 2.2 and verify the following information at Menu > Settings > About Phone:
Android Version: 2.2
Baseband Version: 2.15.00.07.28
Software Number: 3.26.605.1
10.) Remove the PB31IMG.zip from the SD card to avoid an inadvertant reload in the future. You are now unrooted and on stock 2.2

Also adding the RUU option for those that are interested. Thanks again to Doug for the upload/host. For those new to RUU, download to a PC and run from there:

Note for RUU:
You may wish to install HTC Sync (at least temporarily) if you haven't had prior root dealings on your current PC as it will auto-install the necessary driver for phone recognition.

can i just use a different sd card and format it to fat32 then put my other one back in after i'm "unrooted"?
So i did everything right formatted the sd card to fat 32 and named the file right went through everything and now it vibrates once and wont do anything else? HELP!!
NO.....i watched a video.....and everything worked updated and all and when it asked to reboot i did and just a black screen now...also tried pulling battery and nothing is working
Correct. And i've already done it. No need for unrevoked forever. I just used the S-On tool and followed the rest of your guide. Entire process didn't take more than 20 minutes. Thank you!
Could you possible explain to me how you used the S ON tool?
I feel like I'm missing a step.
Thank you for your help.

S-on is a file you download from unrevoked's website. You flash the file in clockwork recovery, like you were installing a rom.
Hey all, read through this sticky and gotta say, what an incredibly helpful bunch of folks!
I would like to ask what may seem like a noob question (probably because i am a noob!).
I've been running CM6.1 for a while now, with root removed manually by deleting superuser.apk and Su.apk, in order to get GOOD for enterprise working. Well, recently, GOOD "updated" and is now looking at "something else" to determine if the phone is out of compliance and now won't run. I need to get it running again so I want to revert to full stock but using the most recent OTA. I'm assuming that's what this is, right?
Ok, that assessed, my current environment is:
s-ON (recently done via the unrevoked s-on tool)
2.2.1 version
2.15.00.09.01 radio
2.6.32.17 CM 6.1 kernel
FRG83 build
Can I use the image file in this sticky to revert to both stock ROM *and* the stock recovery, in one fell swoop, or do I have to reflash recovery separately somehow?
Also, do I need to temporarly re-root with unrevoked, before running this image wipe?
Thanks all!
Yeah the file in the OP will put you back to full stock. No need to root again, just put the file on a fat32 formatted SD card and follow the instructs.
