Is there anything I can do anymore?

This means your mainboard's BIOS/UEFI firmware restricts write access to the flash chip. Enabling writes failed.

This means some part of the flash chip (the ME region) cannot be read.

This is because the ME region is not readable. Why flashrom still tries to read it anyway is rather puzzling.
FAILED! Uh oh. Erase/write failed. Your flash chip is in an unknown state.
This is because flashrom could not read the ME region, and could not check whether the flash chip contents have changed. However, we know that SMM BIOS write protection is enabled, which prevents flashrom from writing to the flash chip. So, flashrom couldn't have modified the flash chip contents.

DO NOT REBOOT OR POWEROFF!
Based on the reasonings given earlier, it should be safe to reboot because flashrom couldn't have possibly changed the flash chip contents.

Thanks,
that's what I actually thought when reading those debug printouts, but ending closure was just soo scary. Yes, it did nothing and computer works as before.
