Downgrade iOS 16 to iOS 15

If you recently updated your iPhone to iOS 16 and have decided it’s not for you, perhaps due to some incompatibility or battery issue or otherwise, you’ll be excited to know you can downgrade from iOS 16 and revert back to iOS 15.

This article will cover an easy approach to downgrading, and you’ll be removing iOS 16 from your iPhone in no time at all.

Prerequisites to downgrading iOS 16

Assuming you meet those requirements, you are ready to remove iOS 16 from your iPhone and revert back to iOS 15.

How to Downgrade iOS 16 on iPhone Back to iOS 15

Be sure to backup your iPhone before beginning this process. If you fail to backup, you could have permanent data loss and lose everything on your device.

  1. Open Finder on the Mac, or iTunes on a Windows PC, and select your iPhone from the sidebar menu
  2. Go to the “Summary” section, then hold the OPTION key on a Mac, or SHIFT key on a PC, and click on the “Restore” button
  3. Navigate to the iOS 15 IPSW file that matches your iPhone model that you already downloaded
  4. Choose “Restore”

After the downgrade has complete, your iPhone will boot back into iOS 15.7, assuming the whole process went well anyway.

This approach attempts to downgrade without erasing the iPhone, but it’s critical to have a backup made beforehand in the event that something goes wrong, or that you choose the wrong option, or that the downgrade fails, backups allow you to restore your data to your device.

Remember, downgrading is only possible for as long as iOS 15.x firmware (or other iOS 15 releases) are being digitally signed by Apple, so don’t expect to be able to do this forever.

Did you decide to downgrade iOS 16 and revert back to iOS 15? If so, why? How did the process work out for you? Let us know your experiences in the comments.

    Sorry apple have stop allowing people to downgrade back to ios 15 on both iPhone and iPad devices. So if you waited too long then you are out of luck and stuck with ios 16.2 or newer only on the iPhone. And also the iPad if you click/tap on the ios 16 update by accident and forgot to cancel it. As for the iPad you can stay on ios 15 for a little longer with no problem beacuse iPad OS 15.7.2 was a option to update to. If your really ready then there was another option that said also available iPad OS 16

    There is no “restore” button there.

  3. Oh Well says:

    Ok well these iOS versions are now all unsigned so it does not work anymore. Might be good to update the article.

  4. HAL says:

    Everything below 16 is now unsigned. Will they sign them again in the future?

  5. Bob The Astronomer says:

    The iOS 15.7 firmware is not signed right now so it’s not possible wait until iOS 15.7.1 and then maybe it is possible again

    But there is no reason to downgrade from iOS 16, it is better all around and barely different.

      Bob,

      some of us want to revert to an earlier version because the new update has caused many issues on our phones. From refusing charging, including not recognizing previous chargers, issues with not recognizing microphone on dictation, etc..

      Unfortunately, it seems this has not become Apple’s playbook. I had the same issues after an update to my old 5S.. Surprise surprise, apple response (whey they have the decency to respond to the glitched they cause) was that they did not support that phone so they “recommend to upgrade”…. How nice… They do not support older versions but they have no issues damaging them with software updates…

      I believe Apple should not be required to support older phones, but should be required to fix issues created by software updates.

    Downgraded from16 to 15.7. No problem. Worked smoothly. But previously 16 backups do not work. Nor does transfer from another 16 iphone. The contacts pics and all icloud stuff returns. No problem there but apps need to be reconstructed.

    bad tutorial, mt iPhone was reset to factory settings, you you said I won’t loose any thing, now am back to square one

    I have fond memories of my first iPhone, the 3GS. The first generation of this model did not have a locked bootloader so could be upgraded and downgraded at will. Today, if you are not satisfied with an upgrade and you’re not quick, downgrading is not possible. iOS 15.7 and 16 being available at the same time is an exception. When Apple have released 16.1 and 15.7 is no longer available, you can not upgrade to this level ‘just to test it’ if you want to be able to downgrade again to a level known to work well for you and your apps.
