Good luck, until you get rid of that programmer initialization error it will never try to read.

Actually now that I think about it, make sure you are using a short fat cable, the BP has to get 3.3v to the chip and this is definately something I ran into.

Looks like it works perfectly under Windows. I was trying before on my own MacBook. I am really bummed now that the SOIC8 clip won't get a grip on the chip... I'll need to wait for a new one. To be continued... Thanks again for all the help, I will buy you enough beers to last for a while

I've tried two different versions of bus pirate with their included firmware, latest firmware, and latest beta.
I can't initials at all you're right. I've never used flashrom before this technique tho so my experience with it and SPI is limited.

This is why I didn't use the BP as the SPI programmer for my tutorial. It is fairly finicky when it comes to reading SPI. You need a short fat cable that is able to carry data of course. And your wires to the clip need to be ~4 inches long. You will need to have the latest firmware on the BP as well as the latest version of flashrom and a bit of luck to get it to work.

dang. i've got the latest firmware, flashrom, and i built my clip harness from 4" leads. looks like i've got everything but the luck, or perhaps the wire gauge is too small

I am not really sure. I know that I had it all correct before but my power cable was the issue, it looked up to standard, but it was definitely not. Why dont you probe the 2v2 and gnd pins while it is powered on trying to talk to flashrom and see what the voltage drops to?

does the bus pirate have a more difficult time providing voltage than the rbp?
i use the same SOIC clip and harness all the time with my rbp, but when connected to bp it won't go
i don't have a 2v2, maybe that's the problem! lol

My appologies I meant 3.3v, the issue usually with the BP is that it cannot support reading while powering a chip unless all the variables are correct.

The SOIC8 clip is being delivered on Monday, so I'll try again then. Can I ask how one should probe or bridge those pins onto the 3.3v? Can you for example use a paperclip to do that or is that a no-go?

you can breadboard the 3v3 out, splice/solder the leads together... any way you see fit.
to probe them you'll need a multimeter or the like, set on VDC (voltage direct current): place the red lead on 3v3 and the black lead on GND

Awesome, I've read out the chip. I made sure to read it 3 times and compared the MD5 hash, which were all the same. I've attached it.

Do you need this cleaned or are you just contributing? (Place in repo mod if needed please.)

Sorry I'm a bit confused, I thought you said we could try and the restore the ME region. So that's why I read out the chip and posted it here. Or is there nothing we can do without getting the proper firmware from the same type of MacBook?

Ok no problem, I guess most questions are for removing the lock. It's a A1297 EMC 2272 2.93GHz, there is also a dump request here:

Alright guys! I've succesfully unbricked my MacBook! 
I bought the chip from eBay containing the correct firmware, I asked if he could just send me the dump instead of the chip and he did. So I replaced the serial number and flashed it on the chip, worked like a charm! It started beeping on startup, looks like there was a faulty RAM module as well. I removed it and it works prefectly.
Thanks a lot for all the help guys! reverendalc and ggltech do you have paypal or something? I see thaGH05T you have paypal. I'd like to buy you a couple of beers or whatever your drink is.

Also I'll put the dump in my other thread so it can be useful to others as well.
