Bricked M1 MBP: can't access DFU mode/restore

[Flow91]

Dear community,

I have a MacBook Pro M1 13" that shows the error "support.apple.com/mac/restore". I want to access it in DFU mode with my 14" MacBook Pro M1 Pro, but I always fail. The MBP 13" shows up in the Apple Configurator, but I think that it is not in DFU mode because a picture of the device is shown, not the rectangular shape with "DFU" written in the middle of it.

When I restart the MBP 13" with the right key combination, the DFU symbol shows up for a very short moment, but I have not managed to stop pressing the keys in a way that the symbol would stay.

When trying to install an IPSW of MacOS on the bricked device, I always get the error "Failed to restore device in recovery mode, libusbrestore error:21 [com.apple.MobileDevice.MobileRestore - 0x15".

As the machine is out of warranty, I'd like to know if there is something I can do to save and restore it as it seems like a software issue to me. I don't care about the data on the SSD, I just want to have it back working again.

I would be very grateful for help or any advice.

Follow the instructions from this video

using the app DFU Blaster, which allows you to trigger DFU mode on a Mac without having to get the timing right on the keypresses.

Thanks a lot for this great hint! I managed to open the DFU mode and to install MacOS, so the MacBook is working again! Great!
