I've had my Gopro Hero 3 Silver for well over three years, I am not a beginner to this stuff. Until this happened, Gopro started acting up about three months ago. First it started to not turn on all the time. Then, I thought maybe I have to update it so I did. After I updated it would stop recording at 30 to 40 seconds in. After it was done recording, it wouldn't let me change to any other selections on the Gopro I was just stuck on record mode. I've tried the hard restart and that has done nothing to it. I need help asap! Thanks.
