I did a dirty port of the Aquaris U2 image.That's a good lead. We can also try the Moto E5 Plus. (Hannah) So we've got 2 matches. The image needs to be arm32. I'll check them out.
What works:
It boots past the splash screen (even without wiping userdata, from my tests), and now the entire screen is used, as compared to a portion of the screen at the top not being used with the one in the past few pages.
What doesn't:
Touch screen, and I'm not sure how to fix it. Can't test anything else because of that.
