I have been up and down the forums and the only thing I can find is references to a -m version or the 3G RAM edition, none of which flash correctly. Most of the images that are 2G/8G etc flicker on my monitor like crazy and are on Android 6. I also tried the Gatos814 version but it has issues on my box.
The only one that seems compatible is on the attached link, which is old and not really rooted on my box. Worst case I can modify it to my liking and upload a copy on here, but I am still confused why there does not seem to be a rooted Nougat version laying around?
Here are some images of my particular board:
