bricking issue

[freestaterocker]

My hd7 has frozen twice in the last 5 days. It stops responding completely, and after a battery pull won't boot past the HTC logo screen. The only remedy is a hard reset. Prior to the first occurrence, it ran flawlessly, and the only change in usage I've made is the addition of a bluetooth headset, namely the Motorola H390. The headset paired and works perfectly, but I'm wondering if the new accessory could be the culprit, as like I said I never had a problem with the phone prior to the addition of the headset. The phone has all the latest updates except the HTC firmware update promised to provide WiFi sharing, which Bell in Canada refuses to push out for reasons unknown. Help?! Where can I find help?
