How to Downgrade from iOS 17.7 to iOS 17.6.1 [u]
This is how to bring your iPhone back to iOS 17.6.1 from iOS 17.7.
If you run into problems on your iPhone and you think moving your device back to an older version of iOS 17 could help and this guide will help you downgrade.
Update: Apple recently stopped signing on iOS 17.6.1 which means you can no longer downgrade from iOS 17.7 to iOS 17.6.1. Do not use these instructions. We’ll let you know when it’s safe to downgrade again.
iOS 17.7 users can only go back to iOS 17.6.11. You can’t go back to iOS 17.6 and you can’t go back any further either. The path back to other versions of iOS, including iOS 16, is closed and it won’t re-open.
Once you downgrade, you can only restore a backup that you made on iOS 17.6.1 so keep that in mind in case you need to restore a backup.
Most users will have a recent backup, but you may lose some items if you aren’t regularly backing up your photos and messages to iCloud.
While this isn’t officially supported, it is easy to do and you won’t lose any customer support or mess with your iPhone’s warranty.
How to Downgrade from iOS 17.7 to iOS 17.6.1
Here’s what you need to do to go back to iOS 17.6.1 on your iPhone. While you are downgrading you cannot use your phone so you will need to open this on your computer or another device.

If you make an archived backup, you can use that after you restore it. If you are doing this right after downloading iOS 17.7, you might have a iOS 17.6.1 backup available on iCloud or your computer.
Follow these steps to go back to iOS 17.6.1 from iOS 17.7:
- Download the iOS 17.6.1 update for your iPhone from this website.
- Make sure there is still a green checkmark in the Apple Signing Status column. If there isn’t one, do not proceed.
- Turn off Find My iPhone on your iPhone. Go to Settings -> tap on your Name at the top of this menu -> Tap on your name at the top -> Tap on Find My iPhone -> Toggle off and Enter your password.
- With your phone backed up and all the steps above completed, plug your iPhone into your computer.
- Open iTunes and Click on the iPhone icon.
This is how this process works if you are still on macOS Mojave. If you’ve already upgraded to macOS Catalina, macOS Big Sur, macOS Monterey, macOS Ventura, or macOS Sonoma, you will need to start this process in Finder. Instead of opening iTunes, open Finder and click on your iPhone in the left side. - Click on the Restore iPhone button using a special click. On a Mac, hold alt/option when you click. On PC, hold Shift when you click.
- In the window that opens, find the iOS 17.6.1 file you just downloaded, click on it, and then click open.
- Choose to erase and restore your iPhone. Click Restore to begin this process
- While you wait the iPhone will restart multiple times. When it is finished you will be back on iOS 17.6.1.
This process takes a little while to complete. When it does, you can start fresh or restore a backup made on iOS 17.6.1. Most people will want to install a backup.
