XG Firewall Firmware Upgrade Failed: 17.5.15 MR-15 to 18.0.4 MR-4 / 18.0.5 MR-5

We are attempting to upgrade the firmware of Sophos XG310 unfortunately it is failing. Firmware v18.0.4 MR-4 is actually present in the backup partition but once we initiate the upgrade, the XG went back to its previous firmware version 17.5.15 MR-15.

We have attempted a few times with the same results.

  • Run upgrade from version 17.5.15 MR-15 to version 18.0.5 MR-5 is not successful
  • Tried to upgrade from version 17.5.15 MR-15 to version 18.0.4 MR-4 still not successful

2 methods we used to run the upgrade:

Definitely, upgrading from 17.5.15 MR-15 to 18.0.5 MR-5 should be supported quoted from this release notes. https://docs.sophos.com/releasenotes/index.html?productGroupID=nsg&productID=xg&versionID=18.0 

Any help/suggestions would be appreciated.

Regards,
Mike
