Where could be the ringtones, wallpapers located on iOS IPSW package? I've used and already extracted the IPSW of iOS 11, there are 4 DMG files there, where could that be on that DMG files there, and where exactly insider one of there could I find that such files?
They're in the biggest of the three DMGs (the one containing the root file system, it's 2.3GB in my IPSW), under /Library/Wallpaper/iPhone:



Ringtones can be found in the same DMG, under /Library/Ringtones.
