Hi I've searched everything I can but can't find answer on this. I uploaded a custom background, and it works but only on main screen. The background won't change on any of the screens, like the Bluetooth screen, radio screen etc.

I've tried going back to one of the factory installed backgrounds, and same thing. It changes the main page but all the function specific pages are stuck with the same background I had before I uploaded my custom background.

Is it not possible to change the background image on these screens from that rising earth?

NEX 5000

As far as I know you set the main screen separately from the "AV" screens (all the other screens). When you set the background, press "AV" on the top and select the background for those screens. That's how it works on the SPH-DA120, which runs the NEX firmware for the most part.
