So I went through a hell of a pain in my rear last night because I screwed up my phone. Finally got an FXZ that worked and am back to stock unrooted JB. I went right to bed as it was updating all my apps. When I woke up I had a warning that the internal sd card is not mounted, it also doesnt show up when plugged in and I don't see any options to format or whatever. How do i fix this or format the internal memory? Factory reset?
