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.
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
