MX100 appliances may become unresponsive and unable to be recovered with a factory reset after upgrading to MX 17.10.5 or MX 18.1.07 from very old, unsupported firmware versions that reflect as critically out of date from the Organization > Firmware upgrades page in Dashboard. We recommend upgrading these devices to MX 17.10.2 first before proceeding to upgrade to either of these newer versions.
