DEC850 importing configuration from another hardware locked me out

Moin!

I managed to shoot myself in the foot by restoring a backup from my current ProtectCLI to my new shiny DEC850 and since then can not access the web UI to any of the ports and while I can connect to the serial console, do BIOS changes and boot into single user with it I can not access the actual console after OPNSense has fully booted. I can control-C during the boot process to get a shell, but not after the machine is booted fully. I also tried to boot from USB to do a re install, but somehow whatever I do in the BIOS the USB stick (connected to the back USB-A port) can not be selected as boot device.

I'd appreciate help in getting the box unbricked.

TIA and so long

Answering myself as the DEC850 is running (though I'm still having problems with the SFP+ ports).

When in single user remount the root file system read-write and the copy a working configuration from /config/backup to /config/config.xml and the reboot. That did recover the box and a bit of regex let me then use the correct interface identifiers from the copied configuration

So long
