I tried every step you mentioned and I can type in my apple ID and password however, it has been "signing in" for about 20 minutes now. At first, it shows the graphics where the apps pop in and out and then when the screen locks and I unlock it, it just shows my name and "signing in" under it. anybody have this happen to them and what did you do to resolve? Thank you in advance for sharing.
