For what it's worth, I can't seem to trigger night mode at all on my H20 2017, running the same firmware version as melodyh (4.5.9587). I followed the recommended steps, but no luck with either using a brightness percentage toggle or setting invertActive to yes.
Oddly enough, it worked fine on my device when I implemented the hack a couple months ago. Then I had to do a factory reset on account of a corrupted database, and now I can't get it working (I made a note of the firmware version before the reset, and it was the same, so there haven't been any updates in the meantime that broke night mode).
Seems like there's just an element of randomness to whether it will work or not. But if anyone has suggestions for further troubleshooting steps, I'd love to hear them.
