Early 2011 MbPro EMC 2419 bad (no error) read bin

I am trying to read the MX 25L6406E BIOS/EFI chip. I have the Raspberry Pi 2 B, using a POMONA SOIC 8 pin clip (although my jumpers are about 8 inches/about 20cm)

I have followed tutorial perfectly. I have to include the chip type "-c "MX25L6406E/MX25l6408E" for flashrom to detect/know which MX I am trying to read.

My issue is I am reading flash and seems to be all well, saves .bin where I want, but when I go to open it, there is only one line of text (even though it says it is 8mb.)

Could this be a clip issue/jumper length issue?
I have the exact computer, but no firmware/icloud and it does the same to the flash read from that chip as well. The text editor reads the .bin dumps from here fine, so I know the text editor should open the file just fine.

Do I need all three pins (3,7, 8 ) going to 3.3v for it to read correctly? I can only attach pin 8 and 7 to 3.3v at one time as I don't have a small breadboard to distribute 3.3v along a rail to attach more jumpers.

When pin 3 and 8 have 3.3v it doesn't detect chip. When 7 and 8 have 3.3v, it detects the chip, reads and saves .bin (but almost empty)

Please help

Thank you!!

I am using an iPad (not iPhone) 12w charger brick.

Believe it's rated at 5.2 or 5.6v

It says 5.2V and 2.4A Should that be enough with keyboard and mouse attached? What power source would you recommend?

Thank you!

Ok. I'll check that tonight. If voltage is good, any other ideas on why the dump isn't "legit"?

I tested for continuity between the chip and the Raspberry and all have contact between chip->clip->PI
I then tested for voltage at the chip and I get 3.156....

Is that too low?

Okay, sounds good. Looks like the last thing I have left is the length of the wires... I'll try that. Thank you.

Very frustrating... Shortened the 3 wires going to VCC and now the voltage drop is even more. I get 3.125V now. I was getting 3.26 at pin 7 but now all three are 3.125V
Odd because the resistance (being that they are now shorter) has gone down, so the voltage drop doesn't make sense...

I will try SSH'ing into the PI. I did test the voltage going to the chip, without the keyboard/mouse attached and it pretty much was the same <3.2v) I will have to test without the HDMI plugged in, which could account for the most voltage drop...

Hopefully SSH will allow this to work give at least 3.2v.) I also ordered newer f-f and m-f wires that are 10cm instead of 20cm. I still need to check where it was manufactured, just in case that could be part of the issue. I did notice that the only text in the flash read is the same as the first line in a "normal/real" .bin from this site. "ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿZ¥ð "

great! I will most likely just buy one when/if SSH doesn't result in a win! haha. I'll report back with my findings. I have tried different boards of the same EMC as well as other EMC boards. I have the same issue with all. So I am sure it is not an EMC chip issue.
