Reading old flash cihp contents - transaction error between offset 0x00003000 and 0x0000303f

I accidentally made my bootsplash image the wrong resolution when compiling skulls, so it doesn't display. No problem, I thought - I'll just replace it with a good one using the "updating" instructions. However, when I try to do that, this happens:

In case it's relevant, I used 1vyrain to flash Skulls.

@kahrkunne It looks like your BIOS is not unlocked. This is an issue for 1vyrain but I suspect you will need to flash externally to fix this.

This happens because the me region is not read-able(as noted in the flashrom log FREG2: Management Engine region (0x00003000-0x004fffff) is locked.). The error clearly states the error occurs at 0x00003000 which just so happens to be the start of me region. It's nowhere near the bios region. bios only starts at 0x00500000. This can be solved by using the -N option for flashrom which skips integrity checks.

[kahrkunne]

Ah, I see, that's the "--noverify-all switch" it was talking about. I did look this up when I originally got that message, but I looked up the flashrom manpage on a difference machine which had an older version which did not include this switch. I added that switch to the x230_skulls.sh script and can confirm that it now works properly!

thanks for reporting! should be fixed.
