I'd restore the backup of the vendor firmware, make sure that every-
thing works as expected and then return to your current setup step by
step.

The flash chips (concatenated together as one 12MiB part) are parti-
tioned into

    Descriptor (IFD) | GbE | ME | BIOS

where the BIOS region will contain the coreboot. You usually don't have
to touch the GbE region, and the Descriptor and ME regions only for the
ME cleaning. I'd start by flashing only coreboot into the BIOS region
and test that first. (The BIOS region covers the end of the 8MiB chip
and the complete 4MiB chip. To test coreboot, it would suffice to write
it into the 4MiB chip as it's executed from top.)
