Reset firmware configuration
In cases where the firmware configuration is corrupt in the config.xml file, we can reset that section of our configuration using the following
command (executed on a console or via SSH):
pluginctl -f system.firmware
Which shows the current data stored and asks for removal, choose Y here to drop that part and circle back to
the section to store the configuration again.
Note
If our factory left a cache file which keeps a “factory-” plugin visible at all times, you can safely remove the reference using the following command:
rm /usr/local/opnsense/version/factory-*
