18. Reset phone and press vol-down to go to Bootloader.
19. Wait for detect and check the Update Package.
20. After checking package, press vol-up to begin update process, IN FIRST TIME AFTER PRESSING VOL-UP YOUR PHONE WILL RESET AND DO NOTHING, YOU SHOULD DO AGAIN FOR STEPS 18,19,20.




Notes

The process will flash your recovery partition back to stock
This process will wipe all the data from your phone
The downgrade installs an official stock HTC ROM with Hboot1.02 (You can s-off with revolutionary and after it You can flash any version of Hboot)
Your sdcard should be fat32 formatted
Creating a goldcard



Thanks
