EFI chip location on Mac Mini A1347 ( Late 2012 )

Hold up .... my SOIC8 clip has 10 wires and the clip head has only 8 connection lines, the last two ( probably CS and what ever is opposite CS ) are cut.

... my CS pin is cut off ... the line does not make it to the clip,

maybe i should go find a place to desolder the chip, and solder it to the board i got witht he SOIC clip .... program it and than solder it back to the board

i also ordered some nicer individual quick clips from DX.com

here ... took the chip out, put it on this board with pins that came with the clip ... not sure if i put it right

so i ran the lines 1-8 like in the picture here and told me there was no chip detected, so i ran them opposite 9-1 and it tells me now that it sees it and does not support it but it gives me now JEDEC ( 7F FFFF ) can i use this info to put custom SPI settings to access the chip ?

 

[kaos42]

i used the pinout settings from the instruction manual from BlackCatUSB

and here is pictures of what it looks like in reality just in case i am retared

 

[kaos42]

here is the program screens ... let me see if i can match the SPI settings from the data sheet

 

[kaos42]

I only clicked the custom setting for SPI and tried to access the chip with them and this is what i got now.

but all i get in the READ / WRITE screen is 1F 1F 1F 1F 1F all the way down .... is this just a fluke because i used customs settings but there is nothing there ?

i noticed that the JEDEC is back to 00 0000

:-(

 

[kaos42]

i closed the program and the JEDEC is now 7F 7F7F .... what is the JEDEC ? i thought maybe it was some sort of identifier but looks like it is not.
