I tried to get my Nexus to switch from MTP to mass storage by using this:

su
setprop persist.sys.usb.config mass_storage
reboot

Now that I rebooted it it doesn't show up on my PC anymore. The phone is charging so there is a connection but I cant access it. Doesnt show up in the device manager either. I tried different USB Slots but it's not working.

Any Ideas?

Also: I accidentally forgot to make a backup. In case this doesn't work out any way to reverse it? Update: I set it back to mpt with setprop persist.sys.usb.config mtp,adb and it works. Still interested why the mass mode didn't work

The value on my device (Stock ROM) is "mtp,adb". With ADB enabled, naturally. But you apparently already figured that out.

Since all data and all apps are stored on the very same memory you're trying to pry from the phone's control, I highly doubt USB mass storage is possible. Apart from the file system issue, of course. It's ext4, so Windows won't be able to access it directly anyway.

Just use FTP.

    It's okay, I'm from the Internet.

It is not possible to mount the internal storage as mass storage without unmounting the entire phone - which obviously won't work.

... very true.  It would be much easier to just partition (while booted into an OS not on the phone), reflash (if need be), and then unmount the partition of interest before attempting to use UMS/MSC with it ;-)
