Hey Muerto, question. Is this program capable of reading information SUCH as serial off a MacBook with T2 chip without the need to desolder the SOCROM chip and reading it? Is there a way to read via DFU? Just curious , or do you have a method or if not is there method in development?

If you can change the serial number on the device without the need to desolder the chip that retains the information of the board such as EFI lock/FIRMWARE LOCK, Serial number of the board then that would be pretty awesome. But in order to remove the MDM lock on T2 machines one has to desolder the SOCROM chip next to the T2 chip. Reprogram with ASPROGRAMMER, and then change the serial with WinHex. Find the serial, DO NOT change any of the code but the serial so it can still normally boot. That is how its done.

No it cannot, it requires a SOCROM dump. Only the T2 has access to the SOCROM, it must come off to be reprogrammed.sigpic
MEOWING IN THE IMPOSSIBLE UNIVERSE!

I see so I am essentially doing the same thing still. This program is good, working progress. Might be a good idea to find a way to get the program to read serials on M1 devices and see if we can find a way to change serial on M series laptops, a good start would be an M1 for now and see if we can get dumps on that and be able to read the serial. If we can manage to do that, MDM removal would be viable for off set devices that companies get rid of and forget to remove their MDM. Very common in this industry at scale.
On Apple Silicone devices, the Scfg in the SOCROM has been either completely removed, or moved into an encoded section. There's not much I can do here at the moment, unfortunately. However, I continue to pull apart and find what I can.

For SOCROM dumps from the SPIROM, the IC is 1.8v 8-USON (or USON8) 4x3mm.
1. Does EZP support 1.8v? If not you need a 1.8v adapter.
2. USON8 4x3 adapter here on AliExpress: https://www.aliexpress.com/item/1005007137888078.html (Choose Color: USON8-4X3-XG)
