Help, using downloaded wallpapers and other stuff.

Hi guys, when I try to install a wallpaper pack for my IPAD its successfully installed but I cant seem to find the pictures or "app" to that wallpaper.

also when I first time opened cydia it said that I needed to restart my iPad but after restarting my ipad just "freezes" at apple logo.
So, i tried and I didnt restart my iPad due to the bug.

but I dont think that all the advantages are downloaded due to not restarting my ipad.


help please.
