Yes. You have to boot a drive with macOS, at least El Capitan. You can use another Mac with firewire Target Disk Mode, too.Ah, OK. So if this new SSD drive is my only drive, I have to install a second drive with a working OS in order to update the firmware of the new SSD?
Run the 10.13.6 Mac App Store full installer, upgrade the firmware, finally you can boot from your createinstallmedia pendrive and install High Sierra as usual.
