Normaly its possible to update your box with this firmware. But when the update does't work, you must contact AVM, to get an recover-program with a new bootloader.

Hi you can use this recover file ftp://ftp.avm.de/fritz.box/fritzbox.../fritz.box_fon_ata.en.04.01.recover-image.exe it makes your box to an english ATA with G729 Support.
