So, the N7 is rooted and I'm using stickmount, which detects the usb as normal when it is plugged in, assigns it a name and everything, but when you open the folder in ES explorer (or any similar app) it is empty!
It is not ROM related, because not only have a tried a few different ROMs, but it is also not recognized at all by TWRP.
Also, keep in mind that: a) it used to work perfectly well, and b) it works fine on my N5!
Any ideas? I've searched high and low for a solution to this, but have so far been unable to find anything, so any ideas or input would be vastly appreciated!
