My STR battery showed up as unknown, and at 1500000 charge. Called support, who had me deregister and register. Did not fix it. Had me take it into the store. There the software was updated, and now my device is totally dead. When attached to the charger, I get a green light, but the device is dead. I was told to buy another one. Any suggestions for a fix?
You could try making a noogie or other bootable uSD card to see if that works. There are instructions on XDA and elsewhere on the procedure.
