Ok, I finally got one tweek that messed up my ipad2 (JB ios5.1). I installed Animate All - HD and then added Bootlogo - Sunset. Now my homescreen is black with all the icons still present and functioning...it's just I can't get my original wallpaper back. I resprung with various settings many times and no matter what, I still have a black screen. Finally I decided to remove both Animate All-HD and Bootlogo, but the black homescreen remains. My lockscreen is fine, however. I've already rebooted (held down both sleep and wake until white apple logo appeared), but nothing changed.
Any thoughts? Thanks.
