Fritz!OS 8 no Bootloader access

bildbaendiger · February 7, 2025, 5:25pm

After updating my Fritzbos 4040 to 24.10, I had to perform a recovery because I could no longer access the box.
The Fritz Recovery installed Fritz!OS 8.02.
Now I can no longer login to the bootloader via ftp (Connection refused).
Is it possible that with the new system the bootloader startprocess has changed and you are no longer able to login via ftp?
I am grateful for any tips.

I observed it once that my Fritz!Box changed its IP address in the boot loader. You can try to find it via the following script (not tested by me, I just found it while looking for possible other address):

github.com

#! /bin/sh

# The following parameters are recognized:

# FROM      - use the specified IP address as source for packets sent
# TO        - use the specified IP address for the target device
# INTERFACE - use the specified network interface to connect to the device
# WAIT      - number of discovery packets to be sent (with 1 second
#             delay in-between)
# BLIP      - show a blip for each discovery packet sent to network on
#             stderr
# HOLD      - hold the target device in bootloader, connect to the FTP

If you are on Windows, there is also a PowerShell version of the script in the same directory.
