Where can i find an img for the nanopi neo4 with root access?

Or could you add a Powerbutton to your img?

I used rk3399-eflasher-android8-20190718

internet adb is not working , there is no option for it in the developer settings.

Further a android ´TV img as radxa provides would be great.
I testet the radxa on the neo4, its working but it is laggy and it hangs.
