I have bought a Fritz Fon ATA from a German supplier and want to convert the language of the software to English. I have downloaded the English firmware from the website but it refuses to load. I think it might have something to be with the freenet branding? I get the error "Die angegebene Datei enthält keine für Ihr Gerät gültige Firmware." The firmware I have tried is fritz.box_fon_ata.en.11.03.98.image Can anyone help me out?
