I have a Fritz!Box 7390 I bought while living in Berlin and would like to switch it to English. I've tried using the Recovery Tool, but it rejects updating the device. How can I update the device to the latest International firmware?

ruKernelTool

You'll need a Windows image for the process, but ruKernelTool allows you to do what you want. The tool and website is in german, but the process is pretty straightforward:

  1. Start the tool and agree to everything.
  2. Click the download tab and allow it to update its links to the AVM servers
  3. Select the firmware you want, in this case 7390 International 84.06.20. Click Download.
  4. Switch to the Network-tab (Netzwerk) and click the Media-Sense item to turn it off. Windows will reboot.
  5. Go back to the Downloads-tab and select you downloaded firmware and click the kernel source button. (als Kernel-Quelle verwenden)
  6. You should switch to the Upload-parameter-tab and enter your WLAN key from the bottom label on the box.
  7. On Upload-tab click the Validate button and it will list out if your choices check out. It will provide warnings in German so you might want translate.google.com handy. (Uberprufen)
  8. Finally start the upload to the device. (Upload starten)

If all goes well your router should reboot, Windows will reactivate Media-Sense and reboot, and your router should have a language selection option. Your router should be accessible via http://fritz.box

On FRITZ!Box 7520:

  • Login to the admin console (try https://192.168.178.1 if unsure)
  • In the right hand vertical menu find the German equivalent of System
  • Under System find the German equivalent of Region and Language
  • Select the desired language

the formal way is to go to AVM website click here and download the correct firmware for your device, in many cases and especially the new routers, they have an international firmware.

Here is the FTP archive and I am pointing to a firmware for router 7330, it shows an English firmware. There is one more piece of information to add here, in Germany we have Annex B which means ISDN and DSL can be on the same line simultaneously, most of the rest of the world is Annex A. You need to adjust the Annex type to be able to connect to your DSL company. Most international firmware has an option to change the Annex.
