You can try flashing the BIOS from post 31 on a new chip (try on a W25R128JW, I dont know of a compatible replacement from MXIC or Gigadevice), keep the original XM25RU128C intact
it's a clean BIOS, it will be missing model/serial number/MTM, you can use Golden key to fill that data

It's strange that you cannot read it, but it works on the laptop

Which programer(s) do you have? I checked the TNM7000 (from your screenshot is this one?) and it supports XM25QU128C, give that a try
It should be possible to read it even with a CH341A and 1.8V adapter

Does it have a NOVO button ,did you try that.

Attached are 2 bios to try from USB recovery.

Thanks a lot, ME.zip worked for me 😍
Renamed to KSCN.bin, powered on pressing fn+r, then released everything. After a few seconds it started beeping (without any flashing LED), then 1 coffee later the laptop was working again
(BIOS version KSCN38ww)

ravenmx Not working? Try with ver. KSCN26WW (same as your original BIOS version), your original BIOS was corrupted in several places, random bits flipped, maybe faulty BIOS chip or programming error, try lowering the SPI clock setting in your programmer to 4-8MHz if using a clip/probe
