Not sure, but maybe you can help me out... I'm trying to replace mine as well. I have the back of the phone disassembled, but can't figure out what to do next. I have unclipped the circuit board that is on the lower part of the phone, but don't know what the next step is. Did you have a guide to help you with this? (Also, are you referring to the HD7 on T-Mobile, I noticed while searching for HD7 disassembly guides I usually get a different HTC (Appears to be a desire branded as an HD7... I need the HD7 that is a Windows phone on T-Mobile USA)
