Massive blind spot on my part - forgot to write what caused it.

I followed the guide completely, and the actual flashing was successful. After 
doing further tinkering on my config, did an internal flash, which resulted in 
this:
```
flashrom unknown on Linux 6.1.0-21-amd64 (x86_64)
flashrom is free software, get the source code at https://flashrom.org

Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
coreboot table found at 0x7fe6e000.
Found chipset "Intel QM77".
Enabling flash write... SPI Configuration is locked down.
FREG0: Flash Descriptor region (0x00000000-0x00000fff) is read-write.
FREG1: BIOS region (0x00500000-0x007fffff) is read-write.
FREG2: Management Engine region (0x00003000-0x004fffff) is read-write.
FREG3: Gigabit Ethernet region (0x00001000-0x00002fff) is read-write.
Enabling hardware sequencing due to multiple flash chips detected.
OK.
Found Programmer flash chip "Opaque flash chip" (12288 kB, Programmer-specific) 
on internal.
Reading old flash chip contents... Transaction error between offset 0x00800000 
and 0x0080003f (= 0x00800000 + 63)!
FAILED.
```
Then everything else followed from that.

I just said you were being very helpful, but that this method ultimately caused 
more problems for me than it solved.

Other #554: Do not follow ch1p's guide on flashing Thinkpad W530 with only 8MB 
chip!!

I had to learn this the hard way and (literally) pay the price (for it to be 
repaired) for following this guide (both on their own 
[website](https://ch1p.io/coreboot-t530-one-chip/) and a [reddit 
post](https://www.reddit.com/r/coreboot/comments/956ymu/howto_flash_coreboot_on_x230t430t530w530_using/)).
 I often make tweaks to my coreboot config which often breaks my system by not 
being able to boot, and thus requires a fully disassembly to access the 4MB 
chip to externally flash. As you can imagine, doing this every time I mess up 
is annoying, and so the idea that I could do it with just the 8MB chip, which 
is easily accessible, was very attractive.

Right off the bat, I'll say this this method causes so many problems and going 
through the pain and frustration is not worth the convenience of not doing full 
disassembly. I was in contact with ch1p who was very helpful in trying to help 
me out. However, it must be said that this guide should **NOT** be followed!

This completely messes up the bios chips' firmware tabling, making it 
impossible to internally or externally flash (while the chips were still on the 
motherboard). You cannot read or write from either of the chips, and the 8MB 
chip thinks it 4MB.

I would get errors like this:
```

Uh oh. Erase/write failed. Checking if anything has changed.

Apparently at least some data has changed.
Your flash chip is in an unknown state.
Please report this to the mailing list at flash...@flashrom.org or
on IRC (see https://www.flashrom.org/Contact for details), thanks!
```

Thanks to [this](https://github.com/flashrom/flashrom/issues/190) github issue, 
I figured the only way to fix this was to have the chips physically removed and 
then flash them. Since I can't solder, I paid someone to do it (they charge for 
disassembly, so saved by dissembling myself and giving them just the 
motherboard).

The bad news is the 8MB always thinks it's 4MB, so impossible to externally 
flash that chip. The good news is the 4MB chip is perfectly fine, which is 
great because that's the chip for the actually bios. From there, you can 
internally flash (both chips), so that problem sorts itself out.

I had to pay someone to fix the mess that the guide caused. If someone with a 
Thinkpad W530 happens to stumble upon this post, you will save yourself time, 
pain and money by ignoring the guide and just dealing with full disassembly. 
It's not worth it.
