Go to this page and fill in the form: http://www.htcdev.com/contact
you'll then receive an email from contact_us@htc.com and will be asked to provide information about the following questions:
* Type of Computer (PC or MAC):
* OS Version on Computer:
* Browser Type and Version:
* Serial Number of Device:
* Hboot version on device (Found on the HBoot screen):
* Software Number on Device:
* Email used to register on HTCDev.com:
Then they'll ask you your availabilities with phone number so they can escalate the problem. That whole email exchange took a week to do so I would highly suggest you provide all the answers for the questions above + availabilities in the form you're going to fill in. That will save you a week or so.
