Successfully Restored My Mac Mini from Linux

Yesterday I performed an SSD upgrade on my M4 Mac Mini yesterday, hello 2TB! :-)

However as I didn't have access to a 2nd Mac, I decided to try restoring it from my Linux machine. After some trial and error and some handy tips from a pinned comment in this video: https://www.youtube.com/watch?v=IzMa-f6u_YM&list=PLjcQKuOVAODu_ofry_y-_0UWVEe6-WCZw I was successful. I'm posting the commands I used below in case they're useful for someone else who doesn't have a 2nd Mac. These worked on Ubuntu 24.04.

Create a new folder and download 4 files from here: https://github.com/libimobiledevice/idevicerestore/tree/master/docker to the new folder
Download the latest firmware for your Mac from here: https://ipsw.me/product/Mac to the folder created above
Put your Mac into DFU mode using instructions from Apple: https://support.apple.com/en-us/
Plug in the USB cable from the middle rear USB-C port on the Mac Mini to any USB port on the Linux machine.
Open the terminal and run "lsusb" to check the if the Mac is detected by Linux in DFU mode (it should show: Apple Inc. Apple Mobile Device (DFU Mode) in the list of USB devices)
In the terminal, navigate to the folder created above and run the following commands:

chmod +x ./build.sh (makes file executable)
chmod +x ./run.sh (makes file executable)
sudo ./build.sh (builds Docker container from source, will take some time)
sudo ./run.sh -e UniversalMac*.ipsw (runs restore command)

Some tips, make sure you use an official Apple USB cable, USB-C or USB-A should work. I had some errors using another cable. The method above needs to be done for an M4 Mac as we need the latest version of idevicerestore and this needs to be built from source. Older Macs can use the method shown in the video I linked to above.
