You can use to put older firmware on your MAG
To make sure they work please install from the recovery area of Mag (hold down menu button 10 during reboot) - Put files on usb (FAT32) in folder named mag*** (*** is your Magbox number e.g.mag256) - Reset to default first then use usb to downgrade.
Make sure you remove ethernet until you have turned off auto update
