Mac Mini M4 Orange SOS DFU Recover Failed OXFCA (4042)

Streaming video then everything goes black. Mac Mini M4 will not display anything. No recovery mode or anything.

Hooked up the M4 to another M4 and did a restore.

failed on Step 4 of 4 during installation. The bar never moved.

Error said.

The System cannot be restored on this device.

Gave up waiting for device to transition from Port DFU state to DFU state. [com.apple.MobileDevice.MobileRestore

- OXFCA (4042)]

I tried it in Finder and Apple Configurator 2.14. No luck.

tried different cords and ports. No luck.

Gave up called support.

Support Level 2 said they recognize that this is a problem and has no solution at this time.

I’m guessing it’s either the SSD is dead or Logic Board.

Open to hear suggestions or experimentations.

Annnnd Go!

I don't know whether this will help but I had an orange SOS problem a few weeks ago and tbirdvet's suggestion solved it.

Try this process: With Mac off hold down the power button until see it will start in recovery mode. From there you can use disk utilities to check drive and then restart by selecting the internal drive. I did this operation the other day for the same issue you have and it fixed the booting issue. When you do this you may need a wired keyboard and mouse.

Your solution seemed less drastic so I thought I would give it a go.

I did it, pressed the power button, got the chime but then nothing!

So I moved across to my M2 you tell you it hadn't worked when out of the corner of my eye I noticed the M4's monitor had the login screen and now everything touch wood (knock on wood) appears to be back to normal.

I reconnected the external boot drive and booted into that with no problem.

So thank you very much.

UPDATE 6/22/25 1:30am: I tried going down a version from 15.5 to 15.4 IPSW. Sadly I get the same results.

I even tried the Terminal approach. Failed.

I strongly believe it's the T2 Chip.

Revive and restore failed.

Level 2 told me NOT to bring it in due to no current fix available.

Sadly it can’t even load this. It has a blank screen with no way of getting into recovery mode. The Firmware is completely gone.
