Hello I have a problem with my ipad. My screen suddenly froze and i could not do anything, not even hard reset it. So i went to icloud.com, and decided to delete all of its content this way. It worked, until i got to the loading screen with black background and the little white circle in the middle. It has been stuck at this point for about 24 hours now, and i can't connect it to my computer? Do any of you guys have a solution for this?
