I'm trying to update my iPhone 5S to iOS 10.1.1 (current: iOS 9.3.2). I downloaded the ipsw through iTunes and tried updating my iPhone.
However, I am getting error code 45 after iTunes says "extracting software".
My iTunes is up-to-date, and so is my Mac. I did check Apple's error code page but 45 isn't listed there.
Any idea what I could do w/o restoring my iPhone? (I forgot to back it up before updating)
