      Did you install all these boards in a single operation? If yes, there is no opportunity to backup the data from the logic to the system or visa versa. If no, did you follow the procedure to backup the data from the logic board to the system board or visa versa? I suspect not.

      If it were me, I would install one of the original boards (SYS or LGC), then backup the data to the new board. The manual describes this procedure quite nicely. Once the new board has been backed up, then you can install the other new board and back that one up too. I would re-load firmware also at the completion of this process.

      If you still cannot boot up, I'd replace the NVRAM. =^..^=
      If you'd like a serious answer to your request:
      1) demonstrate that you've read the manual
      2) demonstrate that you made some attempt to fix it.
      3) if you're going to ask about jams include the jam code.
      4) if you're going to ask about an error code include the error code.
      5) You are the person onsite. Only you can make observations.
