keep on try in any power state, and try to press the power button for two second but dont let the mac power on, close the lid, i have the same model as you, and just sucesfully flashing last night.
1° test on the board:
Placing the "black" probe lead on the 4th pin and the "red" probe lead on the 8th pin the value on the dmm changed from 1 to .004
2° test with the clip:
I connected the clip to the chip and then i placed the probes lead on the wires which correspond to the 4th and 8th pins but the value on the dmm didn't change.
So i presume the clip is not working.
Hello, the position of the wires seems to be good but i have to test them with a DMM.
Also the SPI should be properly enabled but i'm going to search this "self-test" to try.
For the clip i think that will be the last purchase i'll do...
I'll get you back soon about all, Thank you.
