I am writing this because I had to do it. I hosed my phone and could not get it to boot into OS. I did get it to boot into recovery, and fast boot. This will work if you can get that far.
 
USE ONLY FOR EMERGENCY PURPOSES. THIS OVERWRITES EVERYTHING!!!!
 
**THIS WILL RETURN YOU TO FRESH OUT OF THE BOX**
 
You will not need any special drivers loaded, etc...

- Download the stock ROM ZIP image from here: [Evo 3D] - Untouched Stock ROMs - Zip Format and rename it "PG86IM.zip"
 - Copy it to SD Card
 - Reboot phone into hboot mode by holding volume down and then press power. Keep volume down held until you boot into hboot mode.
 - In hboot mode the phone will scan the SD card with the image. Once it finds it will ask you if you want to update. Press "Power" to update.
 - Wait.... For a while. When it gets to "system" it will loop a few times. Its quite nerve wracking actually but after about 5 or 6 times it will complete.
 - Once the entire flash is complete it will prompt you to "press power to reboot." Press power and your phone will reboot to 100% stock ROM.
 - Once the phone has been flashed you will need to set the secure flag on the radio for S-ON to do this use "fastboot oem writesecureflag 3" Make sure you are in fastboot menu. To do this power down and hold power down while powering up and select fastboot. I have attached the fast boot and adb files to the post.
