Bricked ports and communication / please help :)

After one of those system updated my Spark sees no network - I need help. Found some instruction some time ago but it didn’t help and my Spark is idle.

Can you share a good instruction how to revive the device with no internet access?

I am unable to fix it myself

did you try connecting a monitor to it?

Can you still access the BIOS/UEFI menu? If so, can you report the component firmware versions you have?
