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

                  I wanted to update my old post in this threat.. I managed to take down MDM and Activation lock by editing the T2 chip rom.

                    You mean bypass, not take down?

                      No, what I meant was complete removal. with bypass which thats what I was doing before, after any update or formatting the drive, MDM comes back again.

                        Re: Macbook 2018 above firmware password

                        So how does the removal work?

                        Using content from another laptop which was already unlocked?

                          Yes, it have to be the same model and everything. then change the serial number.

                            just curious, I don't know much about that.
                            just need put another serial or other information is necessary ?
                            what's serial number in picture ?
                            a card id ?

                            edit: I was see youtube and some say "Activation needs a valid serial in the T2 ROM and matching uuid, board id etc. This can brick your device."
                            it's true ?

                              You just put a random number. but do not change the whole serial number. for example, this is just an example of one I previously changed:

                              Old S/N: SC02XXC5XJG5J
                              New S/N: SCO2XSC4XJGS

                              I change the 5 for an S, or 0 for O, etc. maximun I change only 3. that should take care it. then apple server add that serial # to their global base.

                                you didn't understand, the weird number is located higher than serial number.
                                look at 2A995D any dump.

                                For serial Apple yes I know how it works.

                                Besides, I directly notice that your "New" is false.
                                Manufacturing Location and week of manufacture are bad .

                                And especially some characters are prohibited !! AEIOUBSZ

                                  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.

                                          as said above, I do not know, not had the opportunity to test the t2.Just curious

                                          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?
