My 11 messed up too. I thought I had automatic updates OFF, but I woke up one morning and my phone was stuck with the apple logo. I tried everything to get it to reset, I couldn’t even make it go to the screen to hook up to iTunes to reset. I went to my local phone store, because I live so far from an Apple Store. They couldn’t help me but said I wasn’t the first one to come in with the issue. I ended up buying another phone. I need to take my phone to see if it can be salvaged at all.
