Step 1: Â Connect your device to your computer using the USB cable.
Step 2: iTunes will automatically detect your device and open up, if it doesn’t open it up yourself.
Step 3: After your device is detected it will prompt for an update, if it doesn’t click the device’s name in the left hand menu and select ”Check for Update”. Make sure your computer is connected to the internet.
Step 4: iTunes will then open a popup saying that an update for your device is available, proceed clicking the “Download and Update” button.
