Will give it a try tomorrow. Now that you mention it, what is that intrusion routine exactly based on? I ask because I didn't completely assembled the HMD, I wanted to make sure it was working before putting it back with all the screws and stuff. I have all the cables connected thou. Maybe the proximity sensor detects the housing is not on? might try putting it back together before checking all the cables again, it wasn't particularly hard a disassembly, I'm used to repairing laptops and other electronics.
Thanks again for your help!
