Changing background in RK261X SDK
 

hi i just bought a mp5 player and the system info says RK261X SDK ID: 1.3.5, the problem i have is that the backgrouds that comes with the player are all horrible and when i open an ebook i can hardly read anything so i wanted to change it for a flat black background or something really dark like carbon fiber or something but i dont know how to do it ive seen other players that when u open the images it has a button that let u set that image as background but mine doesnt have that button, is there a way to change this background?

you might like to try s1res if your player is actions compatible (plays wma)

Your player is a Rockchip Crown, you can only mod the UI if you have a backup firmware.
