![]() T2 is now crackable. This is old news. I can bypass any lock on T2 devices. Currently fighting M1 MacBooks now!

Using content from another laptop which was already unlocked? |

Try not to be negative. what I told you is what I did. and the 9 macs I already unlocked are perfect with no issues. And as for the serial I post, that was not a real serial, it was an example. but if you want to follow my advice fine, otherwise is okay. |

![]() I know that changing 0 in C02 to O causes it to not activate (activation server cannot be reached). Same with changing 2 in C02 to 3. And probably by doing any other SN modification.
So either you did not tell some key detail or it's BS ![]() |

![]() Yes, that I know. The reason I have tried to change C02 on T2 machines is because this method works on older machines. Changing from C02 to C03 removes MDM. But with T2 cloud lock, it doesn't let activate it. That was kind of expected but was worth a shot.
And that's why I know that 5chematic either left some details out or it's just BS. The thing bothering me is that even when you take the ROM from a faulty but unlocked device, it still doesn't let it activate. So the ROM content is still somehow binded with hardware in some way. |

There would therefore be other information written elsewhere for verification that must correspond: ( Mac adress, chip ID or others) or maybe a mirror map hidden somewhere therefore the replacement by full eprom t2 unlocked. It's not good. the activation is not done? |
