NOTE: The logic boards you are placing into your Macbook Pro as a replacement probably are not coming from systems that are current and actively being used (they may have been on the shelf for a while)…more importantly they are almost certainly not coming from systems that were fully updated and running MacOS High Sierra. Realize that if you have updated your Macbook and are running High Sierra, your hard drive has been converted to the latest APFS Apple file system. In order for an older logic board to be able to read any of your APFS hard drive will require that the logic board gets the latest SMC/firmware updates. Without this you will not be able to boot from your hard drive. See how I was able to correct this dilemma here: Hard Drive/OS not recognized after logic board replacement
