1. Connect your phone to the PC via USB and turn it off then while your phone is booting hold up on the DPAD.
2. Run RSD Lite 4.6 as Administrator (For all you Vista and 7 folks out there. If you are using XP you may not need to run as Administrator)
3. If your phone is not displayed in the "model" column you may need to do the following:
1. Select the "config" option from the upper left corner of the tool
2. Select DeviceId Options
3. Select one of the two options available. By default neither are chosen, and my phone shows up fine with neither one selected.
4. Click the [...] next to the filename box and browse to where you saved the .sbf file you want to use and double click the .sbf file.
5. Hit start and below it should give you completion progress.

Your phone will reboot and you will be on a stock 2.01 phone with no root installed.
Credit to ikithme for the original post, Unroot/Unbrick your phone using .sbf, which I've altered slightly here.

You now are on a stock phone, unrooted, just like when you first got your phone. You can apply the OTA (over the air) update files to get to the current version.
I thought it would also help to have a screen shot of TRSD Lite. This is a shot of 4.5.3 but it looks just like the 4.6 I have installed.

Of note:
Your phone, when connected, should be displayed in the Model column.
The Start button is grayed out until a file is selected, but it also becomes available if I hand-type 1.sbf into the filename field.
If your phone is not displayed the Config pull down menu has the DeviceID Options that may help.
