CWWK/Topton/... Nxxx quad NIC router

To my own huge surprise I managed to restore a working BIOS - and I even got the 'target' one, with a single NVME instead of the 4.

How I did this:
- I bought a CH341a programming interface
- as the included clip is physically too large, I also got a pogo pin cable
- I managed to find the correct BIOS on the CWWK site (it turns out that their support sent me the file for the V3 version, ADLNTB, when I have the v4 version, ADLNTC)

And then using one of the many CH341a applications available, it's a simple matter of erasing the chip, and writing the contents of the file to the bios chip. No need to desolder or anything.

I'm amazed it was this easy - worked from first attempt.

Congrats.
Just one note - CH341a is sort of obsolete these days, as CH347 (often on a purple board) is noticeably faster, but not a big deal for a one time job.

As for the pogo pins - I now remember that cwwk p5/p6 boards have bios IC very close to the M.2 slot. I even made a tiny breakout board for that:

Spoiler: pcb

@alkersan thanks for the info, I hope I won't need this again
