Does anyone know how to change the thumbnail that gets assigned to your theme in Theme Creator? By default, you get the Horizon logo, which is a telltale sign you're dealing with a modded theme.
I found some amazing repositories on archive dot org with tons of old 360 dashboard themes. Available to me are the theme file, the four images for the theme, and the thumbnail that appears next to the file when viewed from 360 storage. In Horizon, I see how to insert the four main images, but not how to replace the thumbnail with the correct one for the theme. Is this possible to do?
