My HBoot is HBOOT-2.00.0027, I got the following problem when I was trying to unlock my HTC Desire HD following the instruction

It seems HBOOT 1.0 has this problem and someone suggests to update HBOOT to 1.2, but my HBOOT is already 2.0, should I downside update to 1.2?

HTCdev notes that the Desire HD requires an HBOOT upgrade to unlock. It looks like the most recent version is 2.00.0029. – eldarerathis Mar 3 '13 at 3:43
