Hello all,
I am trying to flash the EFI rom from a 2017 A1534 12" Macbook (Logic board 820-00045).
I have a basic TL866 programmer with the included Xgpro software.
I am using the J6100 JTAG connector to get the SPI_ALT pins in the following format:
Essentially,
Programmer Pins:
However, my programmer cannot seem to detect the chip. I have tried with and without system powered on.
Is there something I have to do with SPIROM_USE_MLB in order for the programmer to communicate with the EFI ROM chip?
Thanks!
