MBA6.2 no Serial Number, Blank Board Serializer -> EFI failure

[julien141]

Hello,

I've updated my MacBook Air mid 2013 from Mountain Lion to Mojave. Since then my Serial Number shows Unknown. I've tried to start Blank Board Serializer but no matter which version I tried the MacBook gave me an EFI error.

Does anybody have an idea?


Greetings
