How do I update my iPhone 11 Pro Max when it won’t connect to WiFi or blue tooth?

You can update it by connecting to a computer (Mac or Windows with iTunes). You can update manually using your computer. Learn how to update your device manually ➔ if you're using a Mac with macOS Catalina or later, or ➔ if you're using a Mac with macOS Mojave or earlier or a Windows PC.
