Android TV BOX( VMEDIA ) Canada

Hello, i currently have an android box through a tv company in canada called VMEDIA. What i am looking to do is remove all of the company's information and reinstall the latest version of android OS on as if it were a tablet. the reason i want to remove everything is because it is taking up space on the internal memory. I am looking to eventually install SHOWBOX and XBMC on it. I keep running out of space so in order for me to update one or ther other is to actually reset the device and reinstall the latest version which is very annoying. if someone could direct me to the right place to get a full instruction on how to do this i would be greatfull.
There is no model number for the BOX besides VBOX
