Mid-2014 MBP 13 Retina flashing EFI-ROM tutorial

Hi,
can somebody guide me to a tutorial on how to flash an EFI-ROM on Mid-2014 MBP 13 Retina?

Especially about:
- how to update the checksum on the Fsys block after changing the S/N
- how to clean the ME region

I need to flash a new EFI-ROM, because something went wrong on Boor Loader Version update on macOS Mojave and I lost all information on the Fsys block.
The result is MBP is missing S/N.

Thanks,
Z.
