Thanks for solving this problem. I used your instructions to do the same for my G20BTS remote. However; "70-local-keyboard.hwdb" didn't work for me so I added the lines to the existing "99-osmcrf.hwdb". The README file in that folder states that "
your files must be named 99-xxxxx.hwdb", so I don't know if that's why it didn't like it? I am on 11 nightly (Dec1).
It's this one, if anyone else need to do the same
