I think you should get a factory USB A-A cable instead of a DIY cable.
I don't care which firmware can hudyj flash to the device, the point is that EVERYTHING should work on the box. (Ethernet too!)
Please keep in mind that this is the LibreELEC forum, so this is not the place to advertise your own Android creation.
It is only a help for those who want to restore their device. Fantasies about advertising are superfluous here my friend.
