It's essential to keep your iPhone and iPad up to date. Not only do iOS updates add new features and fix bugs, but they also incorporate security fixes that protect you from threats you may not even know about. Apple regularly releases updates to iOS, and you can apply these updates directly on your iOS device through the Settings app (this is called an over-the-air update) or via iTunes.
But there are many reasons why you might not want to update in this manner. If you don't have enough space on your iOS device, then you won't be able to apply an over-the-air update. And sometimes over-the-air updates, which only contain the new and changed parts of iOS, can go wrong; iMazing downloads the full installer for the new iOS version. You also may not want to use iTunes for the update, because you don't sync your iPhone or iPad to iTunes.
iMazing can help, allowing you to download and install iOS updates. In addition, iMazing backs up your iPhone or iPad before running the update, just in case something goes wrong.
Here's how to update iOS on your iPhone or iPad:
Download and install iMazing on your Mac or PC computer
Download and install iMazing. Launch the app, and connect your device to your Mac or PC.
Select your device in the sidebar, then click Update to iOS x.x.x. You may need to scroll down in that column to see this function. This button is shown only if an update is available.
By default, iMazing will download the correct iOS update for your device from Apple's servers, but you can also choose an .ipsw file you have already downloaded.
💡 Tip: If you let iMazing download the update, the update file (.ipsw) will be kept on your hard drive for the duration of the session. This means that if you update multiple iOS devices in a row, iMazing will only download updates when needed, i.e. when no previously downloaded update is compatible with the target device. Downloaded update files are deleted automatically when you quit iMazing.
iMazing displays a window asking you to confirm that you want to update your device. iMazing will automatically back up your device.
iMazing downloads the full iOS installation package for your device from Apple's servers.
💡 Tip: iTunes might try to get back into the game during the update. If it does, just close it.
When your device has finished updating, you'll need to type your passcode to use it. Even if you have activated Touch ID, after a device reboot, you need to enter your passcode.
