T2 Chip Programmer Tool

[Stephen]

I was curious if the T2 chip serial being changed would allow cracking the Firmware lock and icloud lock of a device? We came across the T2 Rom Tool and this allows the use of changing the serial which in our experience would allow removal of MDM on older models (2017-and older). Would that isolate the icloud bypass since it is married to the serial of the T2 chip? Curious since we are close to pulling the trigger on a wholesale lot and we anticipate iCloud devices in MacBooks etc. Piernov or anyone have thoughts on this?

Update: People are saying yes and no. If you change the serial you would have to change the UUID? Apple looks at the serial and the UUID in the rom. I know we could figure this out some how some way.

Re: T2 Chip Programmer Tool

The serial can be changed in the T2 ROM without too much trouble. It's a 25-series 1.8V SPI ROM so a decent programmer can deal with it (it's a 3x4mm package so smaller than usual though). Serial number should show up in the dump after "mNrS" string.
I don't know what are the repercussions. I'm probably at least 5 years away from seeing a T2 machine in front of me.

Re: T2 Chip Programmer Tool

change serial on a t2 machine only works for mdm, mdm is linked on serial and icloud is linked on serial, wifi adres,bleutooth adres, so change serial not solved the problem, even the serial is not stored in the t2 chip and cant change it with software, the serial is in a small chip (4mb) and need to solder before can read write

Of course you need to remove the chip to reprogram it. I have used this to change the serial number on T2 twice. The programmer I used was purchased on aliexpress and it came with the bin file and bypass software.

Please share bin files, it would be interesting to study them

How do you identify WiFi address and Bluetooth address in the dump read from small bt and WiFi rom chips?

Activation locks

Re: T2 Chip Programmer Tool

Activation locks

You can't unlock simply by changing values on the dump file.

Re: T2 Chip Programmer Tool

attached are the bin files from the T2 activation
you can run the mina activation tool by putting the MacBook Pro in DFU Mode
but unless you pay the unreasonable $90 to $120 that mina resellers
want for letting you submit the serial you want to use
it will come up with the message "serial no authorised"
you can use the tool with the bin files with the tool but although
successful it will give wrong summary details in about this mac
ie: displays that it is a 13" when it should state its a 16" etc

In the video they also run some script (checkm8 i think) to be able to bypass and activate the machine.
