Summary:

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.

2) Install engineering version of HBOOT to get S-Off (HTC bootloader, something like BIOS for Your PC)

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.

3) Install custom recovery image (recovery is special program which is invoked from HBOOT

in order to flash ROM onto Your device.

Detailed description:

1) Download Paul's Visionary+ tool

3.4) Run ROM manager and select first option (Flash ClockWorkMod Recovery).
