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
