I am trying to upgrade an XG 330 to firmware version 18.5.2. I downloaded the file from the Sophos Licensing Portal and used the Upload & boot option on the Backup & firmware > Firmware page. I have had a spinning wheel for over an hour and a half. The file was 390 MB so I would expect it to take a while, but I have no idea if anything is even happening. The LED display on the XG still indicates the old firmware version. Any ideas? Thanks.
