This is how you go back to iOS 15.4 from iOS 15.4.1.
If you run into issues with iOS 15.4.1 and you think that reverting your iPhone to the previous version of iOS 15 can help, then this guide will help you downgrade.
You can only go back to iOS 15.4. You can’t go back beyond that. The path back to iOS 15.3.1 and below is closed and cannot be reopened.
Updating: Apple recently stopped signing iOS 15.4, meaning you can no longer downgrade from iOS 15.4.1 to iOS 15.4. Do not use these instructions† We’ll let you know when it’s safe to downgrade again.
It’s also worth noting that you cannot downgrade from iOS 15 to iOS 14 and Apple may not open this option again.
Initially, it looked like Apple would let iPhone users stay on iOS 14 and continue to receive security updates and perhaps bug fixes for lingering issues. Unfortunately, those plans seem to have changed.
Apple hasn’t pushed a new version of iOS 14 in months and the most recent version of iOS 14 is gone. Devices with iOS 14.8 and below can only be ported to the latest version of iOS 15.
This is important because it means there probably won’t be a way to downgrade from iOS 15 to iOS 14 in the future. The only way this will happen is if Apple releases a new version of iOS 14.
Once you downgrade, you can only restore a backup you made on iOS 15.4, so keep that in mind in case you need to restore a backup.
Most users have a recent backup, but you may lose some items if you don’t back up your photos and messages to iCloud regularly.
While this isn’t officially supported, it’s easy to do and you won’t lose support or mess with your iPhone’s warranty.
