Cloning FireTV custom build

I am having trouble cloning a custom FireTV build that’s ive been using for long time. I have seen many builds but this one is different. When turning on the box, it loads directly into The build. It opens up to two grey boxes (one saying “Create Amazon Account” and the other is something like “Use existing Amazon Account.”) I know when I got it, the instructions were adamant about not entering anything. I hit the back arrow which takes you to a list of wifi networks. After connecting to my network, it restarts the box. Now every time it’s turned on it loads Kodi directly. No amazon menu at all. The skin being used is Aeon Nox. I really like how it’s layed out and I’ve tried backing up the build using ADB Fire. When I try to restore the build on a new Firestick, it starts to load the build but just keeps loading. It never gets to the main dashboard. Is It because whoever made the build has made it unable to be cloned? Is it because I’m attempting to clone a FireTV build to a Firestick? Any advice would be huge.
