Besides the online update, the firmware of the FRITZ!Box can also be updated offline using a firmware file.

Download the new firmware file from the Internet to your computer. The currently installed firmware version is displayed on the "Firmware File" settings page. The version number of the downloaded firmware is included in the file name. Perform an update only if the downloaded firmware is a newer version.

1. Saving Settings
   A prerequisite for loading a new firmware file is that your current FRITZ!Box settings have been saved. Do this by clicking the "Save Settings" button and saving them as an export file on your computer. Using this file you can restore the settings of your FRITZ!Box as needed.
2. Browsing
   Click the "Browse..." button and choose the file with the new firmware you already downloaded to your computer.
3. Starting the Update
   Click the "Start Update" button. The new firmware is transmitted to the FRITZ!Box. As soon as the "INFO" LED stops flashing, the firmware update has been concluded.

Caution: Do not disconnect FRITZ!Box from the computer during a firmware update, and do not unplug the power cord! If the firmware update is interrupted, your FRITZ!Box may become unusable!
