AVM Fritzbox flashed, configured and boom

Hi there,

I flashed successfully an AVM Fritzbox 4040 with OpenWRT 22.03.3. I configured openWRT over the WebGUI. And after configuration, I couldn´t reached the webgui or ping the flashed router. I remember, I wanted to setup the wan and lan ports. And now I don´t know, how I can reach my router again. SSH switched off. Is there an easy way to reset completly the router ?

Looks like there isn't any special instruction for this device.

Presumably failsafe should work:

If not, you should be able to install OpenWrt again (via ftp), as the ftpd is implemented in the bootloader (ADAM2).
