Our research lab has several pair of Google Glass that we've been using in our research. Recently, one pair (that had been sitting in storage) stopped working - we booted them up about a month ago (they hadn't been used since April 2014) and during the boot sequence, we received several "stopped unexpectedly" errors (for Home, Camera, and Voice functions).
We spoke with Google twice on the issue, and they told us:
(1) The Glass likely lost a connection during a software update, so to do a factory reset we'd need the original device that the Glass were tethered to to initiate a factory reset. Sadly, we no longer have this device, so we cannot initiate a factory reset.
(2) The Glass are out of warranty, so they will not offer any further customer service, other than to direct us to StackOverflow. (stings a bit, to be honest)
So, my question ... there has to be a way to manually reset the Glass via USB? Any help or advice from this community would be incredibly helpful!
