Apple has just released iOS 11 beta to developers at WWDC 2017. If you have not yet updated to iOS 11 beta, and are waiting for a jailbreak, you should stay on whichever firmware version you are currently on. If you are on a lower version that is no longer being signed by Apple, you will not be able to downgrade back to it after updating to iOS 11.
For those of you who have already updated and want to get back to iOS 10.3.3/10.3.2, you can only do so while iOS 11 is still in beta. Once iOS 11 has been released to the public later this year, all versions of iOS 10 will no longer be signed, meaning you will no longer be able to downgrade. So make sure to do it quick if you need to.
Requirements and Notes:
- iTunes 12 or higher must be installed
- You will need to download the iOS 10.3.3/10.3.2 IPSW file you wish to downgrade to from our Downloads page
- This will only be possible while iOS 10.3.3/10.3.2 is being signed by Apple. It will not work once they stop signing it
- You will not need to restore your device in order to do this
- Download the iOS 10.3.3/10.3.2 IPSW file from our Downloads page.
- Plug your iPhone, iPod touch or iPad into your computer.
- Open iTunes and select your iOS device in the top left hand menu.
- Hold shift (Windows) or Alt/Option (Mac) on your keyboard. While you are doing this, click the ‘Check for Update’ or ‘Update’ button. This will prompt you to select the IPSW file you wish to install on your device. Select the iOS 10.3.3/10.3.2 IPSW file you downloaded before.
- Your device will now begin to downgrade to iOS 10.3.3/10.3.2.
