luistobcn · 04-17-2018, 14:02

In the process You use the power button pressed?

Little_Master · 04-17-2018, 15:07

no . I didn't kept the power button pressed.
MacBook was off.
actually spi wasn't detecting the chip untill I disconnected the battery .

I used charger to turn it on, then disconnected the battery to start the process.

iFixSA · 04-17-2018, 15:24

You need to hold the power button when you start to read/write the SPI.
try to do it with xlow SPD mode
unplug the battery and continue by using the charger.

Little_Master · 04-18-2018, 05:21

Thanks for Reply. i AM TRYING WITH POWER BUTTON PRESSED.

Now When I Read Chip it shows its EMPLTY :

[13:46:56] -> Processing image...
Valid Images should have between 1MB and 32MB.Stoping processing image.

Little_Master · 04-18-2018, 06:02

I think I should have use the option " SAVE TO FILE "
But Unfortunatly, I followed this picutre
https://www.dropbox.com/s/083c950ybg...0V1.9.png?dl=0

Where on Step 3 , Arrow is appointed towards Export ME File

:-(

luistobcn · 04-18-2018, 07:25

this tutorial was orientative for the version mac app 3.0.
in the new version 3.1 different reading modes are activated.
but there are videos of some different models and chips with version 3.1

download a .bin file of your model and edit your SN with some program HEX

https://ghostlyhaks.com/downloads/efi-repository

Little_Master · 04-19-2018, 08:44

My EMC No. is 2925
I search file it shows two results :

When attach charger, fan spins , but has no image and no sound.

ANY SUGGESTION ???

luistobcn · 04-20-2018, 06:48

Are you sure that your model is emc 2925 of 2015?.the picture corresponds to models from previous years.

test yourself directly to the chip with the clamp.read and write,xlow sdp.or only full writte spi

for connector isp red 1 you power on wait a few seconds and keep power off.

for fan speed reset smc and pvram.
