Ok, I finally got the HX One updated to 3.71!
Not even sure what did it, as it was still a 30min+ annoying process, but here's what I tried:
- unplugged all midi and ts cables from it (had forgotten to do this before)
- however now both HX One Librarian and Line 6 Central would not recognize the HX1
- unplugged/replugged usb-c cable on both ends, power cycled the HX1, started it in forced update mode, still would not get recognized/show up on macbook
- reinstalled L6 Central, still no luck, HX1 would not show up
- tried different usb-a to usb-c cable, with an A to C adapter on one end (in the past this cable didn't work when I first got the HX1, so I bought the above-mentioned C to C one, that did work but has now stopped working...
)
- for some reason this cable with the adapter worked and the HX1 was now showing up on both HX1 Librarian and L6 Central
- however the update still wouldn't finish and I was getting the same error message, several times in a row, fml
- then suddenly, for no apparent reason, the update finished and is now working!
- I
think I was trying it in forced-update mode, but can't be sure
