MBP 13 Retina A1502 EMC 2875 Serial Number Unavailable

Hey, after update to macOS Mojave 10.14.5 Beta (18F108f), MBP lost Serial Number and now it shows Unavailable.
It was updated from MBP111_0146_B00.scap (Boot ROM Version: MBP111.0146.B00) to MBP111.scap (Boot ROM Version: 151.0.0.0.0) when this happened.

I don't know how to fix it. Is there any other method to put back Serial Number than actually flashing new EFI?
I tried Blank Board Serializer, but it doesn't even start. I guess it's for older MBP and MBA.

Anyone would be able to help?

Model no.: A1502 (EMC 2875)
Order no.: MGXD2LL/A
Processor: Core i7 (I7-4578U) 3.0 GHz

Thanks in advance!

I was able to get a dump of my current Boot ROM Version: 151.0.0.0.0 it's without EFI Password and without Serial Number.

Maybe somebody will find it handy...
