Check Firmware Version
While connected to the internet via an active
Wi-Fi
connection, the Montana 7x0 will periodically check for and download firmware updates seamlessly in the background. Once completed, the
Montana 7x0 will prompt the user to install the
firmware update at the next power-on event.

Should you ever find yourself with a
Montana 7x0 that refuses to complete the boot process and all other options have failed to restore the unit to its former glory, a forced
