Is there a difference to the macbook where i usually can just program with clean me and put back on board? In this case a costumer tried him self and destroyed the chip so cant get original dump, thats why I want dump with clean me and the serial is for that iMac
That's why you need to get your computer working first. You can replace another chip of the same size.
Yes I know but the costumer sent in just logic board even if I told him it maybe not even start but he wanted it done anyware. Should I program with clean me and just send it back without serial programmed?
Serial is not related to programming
So I should not write the serial to the chip?
yes
Ok, I will download clean ME, write to chip and send back to costumer, thank you
clar me plase
