I tried with a file that I managed, the Mac turned on again, but when it restarts, it doesn't come back! need to turn off the button and turn it on again!
Googling, I learned how to get the EFI file out of the macOs installer! I found out that this macmini 6.2 has no EFI file! so i got file from 6.1 (820-3227), mac turned on, but same problem when restarting!
