Hi everyone, this is my first post.
I spent hours and hourse trying to remove EFI Password following the guide ghostlyhaks.com/blog/apple-efi/18-how-to-hack-apple-efi-2
scrupulously and reading many posts on the forum, but the result is always: No EEPROM/flash device found.
So it's time to ask HELP
My setup:
Raspberry pi 2 model b v1.1
Macbook pro a1502 emc2835
chip MX25L6473EZNI
I have no idea on what could be the problem and i'm very very very nooooob on microelectronics but skilled on softwares.
If you need pictures of the setup (raspberry, board, wires, clip etc.) just ask and i'll provide it as soon as possibile..
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.
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.
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.
