Replacing a customers board with a board from my inventory. Board was working but customer wanted SN changed to match. I've done this multiple times without issue.
This time while using Medusa 3 tool I got an error. Tried re applying SN, "Fsys Block not found". Clean ME region - failed. (board still worked at this point).
Replaced BIOS form same board. Fan still spun.
Used Medusa to clean ME region while out of mac by shorting R5116. This was successful but now the board is dead. Magsafe green>orange.
Replaced ROM again with no change..
What did I do?
