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 http://www.htcdev.com/bootloader
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?
