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. However, I do notice that the mac will only boot to the OS via Safe Mode? Does anyone know why this could be happening? This is a fresh install of MacOS + Fresh DFU restore. Feel free to ask any questions. Thanks
