So I decided to prepare for the flashing. 1st I plug the cables in the good ones to each pin Raspeberry Pi 3 to the flash adapter following this : pi4j.com/images/gpio-listener-example.png
All works but when I put this line : sudo flashrom -r ~/efi/read1.bin -V -p linux_spi:dev=/dev/spidev0.0
It says that No EEPROM/flash device found. Note: flashrom can never write if the flash chip isn't found automatically.
So my question is, what's now ? where am I wrong ?
If it may help, the EMC is : 2925 and model : A1466
I'm feel so stupid about this shift...Now it's correct.
So I tried both sudo flashrom -r /home/pi/efi/read1.bin -V -p linux_spi:dev=/dev/spidev0.1 & sudo flashrom -r /home/pi/efi/read1.bin -V -p linux_spi:dev=/dev/spidev0.0 and I've the same message that say nothing found...
Please post the output of addressing both spidev devices.
If you read the output you first shared, no programmer was initialized. We need to make sure flashrom can initialize the programmer before we troubleshoot chip connectivity

ensure your battery is fully charged, and connected to the mac along with the magsafe charger.
remove the VCC pin from your easy flash clip, but leave the rest of the wires (including ground) connected.
power on mac with ALT key until you reach the padlock screen
close the lid, flip it over, and connect to the chip
or
power on mac and let boot to the "this computer is disabled" screen
close the lid, flip it over, and connect to the chip
or
remove the SSD, power on the mac and boot to the [?] screen
close the lid, flip it over, and connect to the chip
one of these configurations should work
i have just done so recently

Doesn't work
power on mac and let boot to the "this computer is disabled" screen
close the lid, flip it over, and connect to the chip
Sadly no
remove the SSD, power on the mac and boot to the [?] screen
close the lid, flip it over, and connect to the chip
I've not the pentalobe, but I'll try when I'll reveive it. Any other step ? :/
PS : I tried to do this with both Rpi2 and Rpi3 and the results are exactly the same.
i'm very confused. it should be working. double-check that all of your wires are firmly connected.. perhaps reseat them? looking at your pictures, it seems correct, but here's another simplified GPIO pinout to follow:
try connecting the VCC, powering the mac off, leaving battery and magsafe connected, and attempting a read.
please share your flashrom command and the output.

Hello, I tried with this but it didn't work BUT I tried something else (YES SOMETHING NEW).
When I pull out the battery from the MAC and connect the Magsafe and do flashrom -r /home/pi/efi/read1.bin -V -p linux_spi:dev=/dev/spidev0.1
I've a new result : pastebin.com/KwfnTupr
EDIT : I tried to pin/unpin the flash adapter, and it says again that he detect nothing...so the issue is probably a pin issue.
EDIT 2 : Ok on the pin on the motherboard broke by a miracle...youhou me and my luck...
