Macbook M1 bypass FMM / EFI Unlock

Re: Macbook M1 bypass FMM / EFI Unlock

On older Macs, removing the internal display connector will force the Mac to use an external display.
On the subject of it being locked, I'm afraid you'll have to wait for an unlock to be made available on here.

yes sir. i turned off the internal display, but dont get picture on external monitor.

Here is the SOCROM read .bin fine from MDM Locked M1 Mac

It is not Windbond, in my case it is Macronix.

I checked your bin file and I found a serial number which leads to an IPhone 12 Pro 128GB Pacific Blue A2407

If you do a full nand read, try to backup winbond chip also as a pair, it migh hold some keys to open data on ssd.

Re: Macbook M1 bypass FMM / EFI Unlock

I have also installed both NANDs to a known working iPhone X so I can read the data with Purple Mode. When NAND is installed, the phone goes in recovery mode and purple mode fails to connect. When I try to restore software with iTunes it gives error 4014 because underlaying data is not correct.

So no luck in reading the SN from M1 Mac NAND with this method.



I will try to read data from my personal mac and write it to this locked mac and test

Re: Macbook M1 bypass FMM / EFI Unlock

I have read the data with HxD software and tried decoding with all available options, but none decode to anything that makes sense.

Re: Macbook M1 bypass FMM / EFI Unlock

I believe it's encrypted and I don't know how to decrypt.

Re: Macbook M1 bypass FMM / EFI Unlock

Here is data from the left NAND

Re: Macbook M1 bypass FMM / EFI Unlock

I have read the right NAND on M1 A2338

https://drive.google.com/file/d/1mQo...ew?usp=sharing

Here is the data. I can't see the serial number

Re: Macbook M1 bypass FMM / EFI Unlock

thanks, i will waiting for checkra1n release new version , and i will buy full tool,
hope it comes out soon

Re: Macbook M1 bypass FMM / EFI Unlock

A 3.3v to 1.8v adapter is only $5.
Bear in mind that you’re repairing a MacBook worth $500-$2000. A $20 investment is worth it to have the correct tools.

Re: Macbook M1 bypass FMM / EFI Unlock

ah, sorry, i understand rightnow, you adding AMS1117 1.8V to convert 5v usb --> 1,8v for vcc T2 rom,

Re: Macbook M1 bypass FMM / EFI Unlock

oh, really? i see in this picture, you are using "DIP8-SOP8 0.65mm". does it fit for "uson8 4*3 "???
and why you add capacitor to transistor and jump to 8 pin adapter? ( I think it convert 3v3 vol to 1.8V to use with t2 chip )
sorry for dumb question, i am a newbie D

lifehack to all you

Re: Macbook M1 bypass FMM / EFI Unlock

A DIP8 to SOP8 won't work.
You need a board from AliExpress called "serial number modification tool T2 chip unlocking BIOS reading adapter board" as posted by betonel.
This has USON8 and other types of useful pinouts.

over 20$ in my country very expensive, what do you think when I use copper jump wire to connect T2 Rom chip in Adapter "DIP8 to SOP8"

Re: Macbook M1 bypass FMM / EFI Unlock

We're all waiting for new checkra1n release as it stands.
