Does anyone know how to fix this? I am so tired of these update fail notifications… Never happened before, only with iOS 9.3.5. I will highly appreciate it if you can comment the solution…
It’s driving me crazy too… I’ve done all of that multiple times, and nothing. I worry that my data is now vulnerable, as this was an important update for a security reason. Let’s hope that iOS 10 will install smoothly…
