Well I stopped after the "sudo make install". The installation of the latest flashroom version.
I was stuck on the "sudo nano /etc/modprobe.d/raspi-blacklist.conf"
I started all the process with the "sudo raspi-config".
Before this, Ghost wrote 7 steps I never succeeded to follow. I was stuck on step 2, "read the chip 3 times and verify md5 check-sum to ensure you have a good backup if things go wrong".
I think I need notepad ++, a program on raspberry pi ? Hex editor aswell ?
If you think it's too risky to do it without these 7 steps done, may be we should go back on this first.
Thank you again for your help, and sorry to be such a beginner about all of this.

I use HxD hex editor on a windows box to edit the dump file. I would not recommend notepad ++ at all!
There are tons of serviceable hex editors. I use iHex on my Mac and there's even a decent graphical hex editor you can run on the pi, I forget the name.
When you said you were stuck on editing the blacklist-conf, does that mean you didn't complete that step?
If you don't configure the pi and the wiring correctly, it's sure not to work.
It's all quite simple, and laid out step by step. Each instruction does play a key role in preparing your raspberry pi to work, so make sure you complete them and achieve the desired result.
If you are struggling with something, just ask for help
Well I feel ashamed to say that, but I don't have a clue about how to do this.
I don't understand step 2, what is this chip I should read 3 times ? Is it the thing in the mac where I will plug the clip ?
I don't even know what MD5 check-sum is... It will be hard to verify it.
No need for shame... Everybody has a first time. Perhaps your prerequisite knowledge is less than others... But the step by step directions should help you through the process without fully understanding what you're doing.
I'm sure many people will be happy to lend help, however we can't come do it for you so you'll have to let us know exactly where you are in the process, what you're stuck on, and any errors you're receiving.
Have you successfully read the chip? Assuming you did, and did so three times, you'll have read1.bin read2.bin and read3.bin (or whatever you named them)
Then type "md5sum read1.bin read2.bin read3.bin" without quotation.
It should display identical output for all three files.
Connect your raspberry pi or other programmer to the ezflash tool, and connect that to the service connector on the logic board.
Then (on your pi if so equipped) run the flashrom read command.
Again, you're not giving us any information about where are you are in the process or what's holding you back.
Do you have the pi connected to the ezflash? Do you have the ezflash connected to the logic board? If flashrom is giving you an error, what error is it?
All I did was testing my raspberry pi, discovering it.
I didn't do the 7 steps.
I went to the terminal and tested almost all the "sudo" in the guide we must type after the 7 steps.
I started with "sudo raspi-config" and finished on "sudo make install".
But that was just to test my raspberry, if I want to unlock the mac, I will have to do the 7 steps I never did first, and then I will have to type those sudo again.
Now I'm still stuck on the step 2, reading the chip 3 times.
But before I do anything, I have to do what you said:
" Connect your raspberry pi or other programmer to the ezflash tool, and connect that to the service connector on the logic board. "
