The wires are ~20-25cm made of aluminium, but I have some broken USB cables with copper wires. I can reduce the distance of laptop's keyboard connector and DIP8 socket to about 5cm wire length, will give it a try tomorrow. And something that I've noticed at verifying with flashrom, it always gives a random hex number after "failed byte count from 0x00000000-0x0001ffff". Maybe the "Timed out waiting for SPI not busy!" error is caused by the wires too. Thanks for the idea, I will reply back with results.

Sorry if I've already asked this question, but how long are your wires? Ideally they should be about 10cm length and made of good copper. Although it could work even for 30cm poor aluminum wires, still when there are read/write errors - the first suggestion which comes to my mind is to shorten the wires. I understand that it could be difficult to use short wires at your flashing setup, but hope it is possible for you to try. And also I hope that you've ordered CH341A just in case our suggestions wouldn't work.
The laptop can't boot, doesn't even react to power button or recovery
key combination, and no charging LED lighting up Everything from this list is expected if there is a corrupted KB9012 firmware, because it is KB9012 which listens for your power button keypresses / controls the LEDs / etc

Sorry for the confusion. :( I think you have misunderstood me.
My laptop's motherboard is taken out of the laptop. I have another
machine, a desktop PC which I've used for trying rayer_spi programmer. Now I connect the laptop's KB9012's debug pins into the desktop PC motherboard's DIP8 BIOS socket with wires, after it booted the linux distribution with flashrom installed and removing it's original BIOS SPI chip. The two machine's GND, DIP8 socket's GND, and KB9012's pin 42 are united.
Like when recovering a regular motherboard BIOS with hot-swapping chips,
just the only difference I connect the laptop's KBC instead of another BIOS chip: https://www.coreboot.org/FAQ#Developers
I think the desktop motherboard's BIOS socket can be used as an SPI
programmer this way, originally it has W25Q80BVAIG DIP8 chip which can be removed. That gave me these results, read and write errors which I sent before, but at least it can detect KB9012. I've tested with the original BIOS chip, flashrom can read, erase, and write it. The motherboard is an Asrock G41C-GS first generation, rev 1.0.2.
The laptop can't boot, doesn't even react to power button or recovery
key combination, and no charging LED lighting up, since it got bricked with a wrong BIOS update, this is why I want to reflash KB9012 with an external tool, like the desktop PC motherboard's DIP8 socket.

That is because KB9012 is active after your laptop has booted and not in debug state where it is possible to reflash it without a problem.
Have you double checked your laptop's datasheet to make sure your connection is correct, and also that your laptop's corner ground is really connected to its' ground? (what if not all its' copper circles are the grounds in your case)

Finally managed it to detect KBC's internal flash using the
motherboard's BIOS socket with removing it's SPI chip after boot, and connecting KB9012 in there. But the read always gives me different files, so I can't backup the current content of KB9012.

Yea, tried to discharge the motherboard, taken out CMOS battery
too, it didn't help. I don't know if this is programmer related or not, I have reflashed 2 types of BIOS SPI chips with it, EN25QH16 and W25Q32BV. But these chips are maybe different from KB9012's debug interface. I can't get a CH341A for now, maybe some months later. It would be good to recover the laptop if it's possible with the tools I have currently, but not very urgent. Here is the programmer's config, if it helps: https://github.com/flashrom/flashrom/blob/master/rayer_spi.c

grounds are united, still the same error happens. I have tried to GND pin 42 of KB9012 as mentioned in the guide, and tried to connect both pin 41 and 42 to GND, as in KBC's datasheet at EDI related part, still no success, flashrom doesn't detect it.
