Just got the S2 back from warranty repair and wanted to set the lockscreen and home screen to the original samsung 'dandelion' image (I had it before) but it's not there in the available wallpapers when selecting what you want. Phone is running the same android version 4.1.2. Any idea's please? There's lots of copies out there, but I'm after the original HD version - the one you see on the TV adverts etc. but NOT the live wallpaper. Help!
