Apple finally released the final version of iOS 11 to the public which includes several cool features and improvements. There is a lot of excitement whenever Apple releases a new major iOS software update, so it is quite understandable that the natural instinct is to install iOS 11.
If you’ve installed iOS 11, but want to downgrade back to iOS 10.3.3, because you found it too buggy or it is draining battery life then we’ve covered. Downgrading from iOS 11 to iOS 10.3.3 is quite easy as Apple is still signing the iOS 10.3.3 firmware.
- You will be able to downgrade back only to iOS 10.3.3, which is the latest version. You cannot downgrade to the previous versions as Apple has stopped signing the older iOS firmware files.
- Please note that the process involves wiping your device, and then restoring it from a backup, so it can take some time depending on how much data needs to be recovered and your internet connection (if you’re restoring from an iCloud backup).
- Please use this procedure if you have an iCloud or iTunes backup of your device as it involves wiping your device.
- The standard iCloud and iTunes backup will likely be iOS 11-based, so it may not restore properly to an iOS 10.3.3 device. So it is important to have the archived backup you made before installing iOS 11 as we had recommended.
To find out if Apple is still signing the firmware file, checkthis website. Green rows with a tick mean that Apple is still signing the firmware file, and you can downgrade from iOS 11 to iOS 10.3.3.

- iTunes will now verify the software and install it on your device. It should take around 10 minutes.
- After it is successfully restored to iOS 10.3.3, you should see the white ‘Hello’ screen. Follow the on-screen instructions to set up your device, and restore your device from the archived backup you had made before installing iOS 10 to restore your personal data.
That’s it. Your iPhone, iPad or iPod touch should now be successfully downgraded from iOS 11 to iOS 10.3.3.
If you get the error message “This device isn’t eligible for the requested build” then it is probably because you’ve downloaded the wrong firmware file for your device.
