Which new firmware? The one you linked earlier in the discussion, or the new setup with the one git commit reverted?
Either or both.
The GIT commit reversion should be similar enough to a manual change I tried with both 4.9 and 4.10 I can almost certainly say it would work (trying the old firmware manually). I haven't tried the other, and won't be able to for about 5 hours (away from the desktop in question).
