Do you set MTP settings to Mass storage?

Maybe this is your problem if you didn't set it to mass storage and maybe damaged cable or usb port on your Pc.
Do you set MTP settings to Mass storage? How do I do this? no mention of that in the tutorial. Cant be a damaged cable and nt a problem with USB ports either. I will give it a charge again on the way and back from work.

Tried all that and it still powers off during map install. Be handy if i could get the map files required to install them by pasting them little by little.
