I try to review all your post here, but is not clear for me what is not work proper for you.
If you are still on Android 7.0 please describe what is not work for you.
So,
- Box video output is 1080p or 2160p?
- Auto framerate switching, is not doing switching with HiMedia 24Hz off?
- Have lost HDMI signal randomly when video is playing?
- Did use Q5/Q10 Pro Output Info Diagnostic Tool, to understand what is not work for you?

If you already switch back to HMD 1.0.7 and you are happy with how is woks, don't need spend time to try again Android 7.0 HMD 2.0.0.
Wait new f/w 2.0.1 to come out, probably in 2nd week on January 2017.
Ok, so is not working with FW 2.0.0 Android 7.
I will go back to fw 1.0.7.
