Thank you for the information.
I noticed that the image that older flashrom produced was less than half
a size of Intel's rescue image.
I think that it still should be possible to unlock the hardware via
software (or something like that), because Intel has a tool that updates
BIOS from within OS (you guessed it right - available only for Windows).
