I'm also not seeing any specific BIOS/firmware files in the download section of the Juniper MX Series portion of the Juniper website.

It is a hidden command, so you have to manually complete it. After the firmware it starts to auto complete:

The output above is from an MX240 with SCB.

I have never seen that error showing up but from what i have seen on similar situations the firmware should be embedded in junos and the firmware upgrade should just work without additional files. But SCB seems not to be a valid upgrade target on MX:

tested on MX480 with SCBE

Would you by any chance have bought SCBE2 (they would probably not been available in used condition) instead of SCB. Just asking because SCBE2 is supported starting from 13.something and does not work in 12.3
