Problem booting OpenWRT after flashing

[FKuypers]

I had OpenWRT running on my router, but a power outage kind of killed my Image yesterday.

I recovered into Stock Xiaomi image using TFTP and used the python scripts to enable network mode:4 and SSH to install openWRT using the factory.bin image mentioned on this page.

So far so good.

After the reboot I get the following error:
