Hi, I am stucked with the "slide to upgrade" error when I tried to update to IOS 9.0 two days ago. The 9.01 update was released yesterday (23. sept) I think, but I can´t now manage to either restore it or update it to 9.01. Is there a way to totally delete all the content on the iPad and set it back to an older factory reset? iTunes won´t let me this, so I presume I need to go into somekind of special settings or take it back to the store and have them fix it. Any ways to fix this and get around this bug?
