Hi there,
I'm having trouble with the MBP A2159 I have here. It originally came in with a fault with no being able to install the MacOS. You could not DFU restore or internet recovery. I tried many different things (New housing, new DFU cables, New mac's for DFU), nothing worked. I then removed the SOC Rom from motherboard (T2), and reprogrammed with a known good bin file. I then restored the SN. After doing a DFU restore, the Mac worked. I then re-installed the OS and it then came up with an MDM lock. I then got another serial number from a donor board and used that. MDM lock removed....

Hi there,
Thanks for the response, and doing that for me. I have gone to power the laptop back on but an amber light comes on, and then goes back off as soon as I let go of the power button. Flashing went ok. Any thoughts on this? ThanksLeave a comment:

Hello,
I have a Dell Latitude 5420 stuck on the Dell Security Manager message/MDM lock on startup, I can't do anything.
Here is my BIOS and what I assume is ME (32MB for BIOS and 1MB for ME). I have attached 2 different dumps I took, as when you try to read the ic, it will not show in the list, so I had to select another type of chip someone said works with the bios chip on these laptops.
If someone could remove my BIOS password for me so I can reflash it afterwards.

Hi there,
This is my first post. I just wanted to come here to get a clear answer from some people about MDM removal on the 16 inch 2019 A2141 MBP & 15 inch 2018 MBP A1990. I have seen a lot of things on MDM removal, and wanted to know exactly what is needed to remove it, and what the best option is in 2024 when running Sonoma.
I know that Checkm8 have an MDM removal service now, that seems to be a permanent removal. I also have heard you can remove the T2 ROM and use a programmer to read the data and change the serial number. Im not 100 percent sure if this is a... -
