1) Download Paul's Visionary+ tool (I have used version r12) (google removed this app from market) so You will have to download it from Paul's website.
This tools enables root and removes new HTC protection.

This step is optional and it's not required in order to flash custom ROM's on Your DHD but gives You more freedom with Your device.
