Lost Access to Firewall

Dear Community,

unfortunately, I have a bigger problem. I created a super-admin with a Fortitoken. Due to a defect, I had to factory reset my smartphone, and therefore I lost my Fortitoken. So I can no longer log into the firewall. I have a backup file with Fortitoken already activated, and the backup file is unfortunately also password encrypted, which is why I cannot remove the 2 factor line. Unfortunately, the maintainer account is also no option because the command Full Config is deactivated. Does anyone have any idea whether there is a possibility to activate the command Show Full Config for the maintainer account, or if there is any other possibility without having to reset up my entire system?

Thank you very much
