I'm trying to restore an ASA 5505 to the factory defaults. According to the instructions from several sources (e.g. http://www.mailbeyond.com/restoring-factory-defaults-to-the-cisco-asa5505-firewall-via-the-console) I need to run the following command:
ciscoasa(config)#config factory-default
But this returns:
ERROR: command can only be executed in single router mode
The command to put the ASA into single router mode should be:
ciscoasa(config)#mode single
But this returns:
ciscoasa(config)#mode single

ERROR: %Invalid input detected at '^' marker
