Restoring the serial number (MBP Mid-2014 - A1398 (EMC 2876))

Per the instructions on this site, I was able to remove the EFI password successfully.

I believe I may have accidentally blown off the serial number.

All the assemblies are original, so the main logic board's serial number should be the same as the serial number printed on the MBP's case.

Any advice on how to put back (flash) the serial is greatly appreciated.

Thanks!
