To recover the Barracuda NextGen Firewall F-Series, format a USB flash drive and import the NextGen Firewall F-Series ISO image to the drive. You can also include PAR/PCA files and hotfixes. If you are including a PCA file, verify that the password for the PCA file is set to the serial number of your hardware appliance.
