Apple certified service technicians uses Apple netboot diagnostics called AST to serialize a newly replaced logic board. Alternately, they may boot to a blank board serializer software. I'm sure if you take it to the Apple store, they can do this for you since it would be detected that your MLB is blank and needs to be serialized when they run their diagnostics. Where did you purchase your logic board?
