I recently bought a mp3 player from amazon .Overall its decent but the shuffly is bad and the wallpapaer settings only allow a certian inbuild photos as wallpapaer.So I was wondering if there was any way possible to update its code so that I can atleast change its wallpaper to something cooler than a goofy image of moon.
