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?

  • 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
