Part one: Prepare your device before you update to iOS 12.2 beta
- Make sure that you have the latest version of iTunes.
- Connect your device to your computer and open iTunes.
- You can make a backup that isn’t encrypted. Just click Back Up Now.
- Wait for the backup to finish. Then go to iTunes > Preferences > Devices on your computer.
- Archive or copy your backup
If you have a Mac, Control-click the backup that you just made, then choose Archive. If you use Windows, find your backup, copy it, and save the copy to another location. If you decide to go back to the current version of iOS, you’ll need this archived or copied backup.
- Update when an alert says a new iOS update is now available
If you see this alert, it means that the version of iOS beta on your device expired and you need to update. Tap Settings > General > Software Update and install the update.
Part two: Uninstall iOS beta
- Check that you have the latest version of iTunes.
- Connect your device to your computer, then put your device in recovery mode.
- For iPhone 8 or later: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Then, press and hold the Side button until you see the recovery-mode screen.
- For iPhone 7 or iPhone 7 Plus: Press and hold the Sleep/Wake and Volume Down buttons at the same time. Don’t release the buttons when you see the Apple logo. Continue to hold both buttons until you see the recovery mode screen.
- For iPhone 6s and earlier, iPad, or iPod touch: Press and hold the Sleep/Wake and Home buttons at the same time. Don’t release the buttons when you see the Apple logo. Continue to hold both buttons until you see the recovery mode screen.
- Click the Restore option when it appears. This erases your device and installs the current nonbeta version of iOS.
- Wait for the restore to finish. If asked, enter your Apple ID and password, which disables Activation Lock.
- After the restore finishes, you can set up your device from your archived backup, which should be from an earlier version of iOS. If the restore process won’t finish, iFonebox can help you extract specific data from iTunes/iCloud backup with ease.
