Firmware update error: File is not an update file
Hello all, I am trying to update the firmware of my old Fortigate 200A to the latest version. Currently running Fortigate-200A 2.80,build359,050210. Tried updating multiple times via the GUI with these firmware image files (confirmed checksums)... FGT_200-v280-build184-FORTINET.out FGT_200-v280-build219-FORTINET.out FGT_200-v280-build250-FORTINET.out Each time I try after 30 seconds or so I get this error: Error File is not an update file. Any suggestions? The aim is to eventually get up to the latest v4.0MR3. Thanks, Derek
