zmaint After abit appears a programming cable issue
My cable uses the same chip as your cable and it doesnt work
But Using the different cable on the ft-60 with the appimage it works fine.
So long story short the appimage works fine.
FTDI FT232R is the chip in the cable that works
Found this after all that work https://chirpmyradio.com/projects/chirp/wiki/CableGuide (explains issue)
Confirms what I was thinking and why mine worked I guess those cables with that chip are hard to find
Bluemax appears to have it (and cheaper than rt systems) (as with anything would ask returns policy if you get one)
Hope I helped and it fixes issue. (from the net seems be more common issue )
Note is the way I see it for good or bad you will have decide what you want to try
