I installed a new camera on my p3s... (exact replacement) .. Camera's not working, no signal. I formated the SD, got a copy of a firmware update bin file,. Now I can't find an app that will that will decompress the file.... they all just let me view it... there's got to be an easy way to fix this.... also, I saw a vid here on the forum showing a tiny reset button on the side.... does the p3s have one I can't see?
