I have the file for ASD 3S156 installed on a partitioned USB stick. With the EFI 3S156.dmg file I tried doing the restore method with disk utility as the pdf file says to do. I would get an error so I just followed what louis said in a previous post to put the EFI or OS .dmg file on a partition and boot into it with the option key on startup. On startup I held the option key but the only drive that came up was the Macbooks SSD.
Here is a video of me trying to install it onto the usb https://youtu.be/RYdTpbfrUro
