This is a quick how to get MTP working on Linux, the guide is for distro's based on Debian (mint\debian\ubuntu)
Debian based distros
Code: sudo apt-get install mtpfs
sudo mkdir /media/onex
sudo chmod 775 /media/onex
sudo mtpfs -o allow_other /media/onex
gedit /etc/udev/rules.d/51-android.rules
and add the following line:
SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", MODE="0666"
and then:
sudo service udev restart
