How to downgrade iOS 17 to iOS 16 without losing data

Apple unveiled the exciting new iOS 17, and we already have a post on how to download and install it. But since it is in the early beta stage, the new features come with countless bugs and glitches.

If these bugs are bothering you a little too much, here’s how to downgrade from the iOS 17 to the iOS 16 update.

Things to know before downgrading iOS 17

  • You need a Mac or PC to downgrade from iOS 17 to iOS 16.
  • To download the IPSW file, you need a fast, stable internet connection.
  • You cannot restore the iOS 17 backup to iOS 16. Thus, make sure you manually back up any new documents, images, files, etc., you created while using iOS 17 to services like iCloud Drive, Google Photos, and One Drive. Later you can re-download these on iOS 16.
  • If you have an archived backup of iOS 16, you can restore your phone data before you install iOS 17.
  • If you don’t have iOS 16 backups, you will have to set up your iPhone as new after downgrading.
