Unknown Internal Module - x10S

[Confused_x10s]

I have a non-express horus x10s with the iXJT board. It is correctly running ETHOS (really nice ui), but when I go to System->Info it says Internal Module is 'Unknown'. Reading different forums and posts seems to indicate that maybe it was flashed with the wrong firmware, maybe the 'express' ones for the wrong RF board.

I tried to download FW-iXJT-HORUS-v2.1.0 from the frsky webpage for the x10s, but it is an *.frk file and nothing will let me flash the internal module with that file, even if you rename it.
Someone in a thread posted a link to a file named ISRM-S-X10S_2.1.0.frsk, which is the right file type, but if I understand correctly ISRM is the different FR board?

At this point I am just lost. Is there a version of the firmware somewhere that will work with this transmitter and RF board, or do I need t spend $80 and swap it out with the ACCESS Upgrade Module Kit?

The non Express radio needs the ISRM ACCESS board and new firmware for it to work
