Apple has just released iOS 10.3 for iPhone, iPad, and iPod Touch and it comes with many new features including an all new Find My AirPods feature that allows you to find the location of your missing AirPods. The new software also includes expanded SiriKit support, which makes it easier to pay bills, schedule a ride-hailing service, and even check on the status of a pending payment.

You can update to iOS 10.3 over-the-air by going to Settings -> General -> Software Update. If you’ve already updated to iOS 10.3 and have been facing issues with the latest firmware, then it is still possible to downgrade back to iOS 10.2.1.

Users who wish to jailbreak should remain on iOS 10.2.1 as it may contain exploits that may be used in a future jailbreak tool for this firmware. Therefore, if you have upgrade to iOS 10.3 and wish to jailbreak, we recommend that you downgrade back to iOS 10.2.1 to increase your chances of jailbreaking.

In today’s tutorial, we will show you how to downgrade iOS 10.3 to iOS 10.2.1 using iTunes. Keep in mind that the downgrade is only possible if Apple is still signing iOS 10.2.1. As of this writing, iOS 10.2.1 is still being signed. You can check the signing status from here.

Here are some important points to consider before downgrading:

  • Please note that the process involves wiping your device, and then restoring it from a compatible 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).

    Note: you can downgrade to iOS 10.2.1 if Apple is still signing the firmware. You can check the signing status from here.

    Step 1: The first step is to download the iOS 10.2.1 IPSW file for your device. Make sure that you download the correct firmware that corresponds to your device model.

    Note: If you’re downloading the firmware file using Safari then ensure that auto unzip feature is disabled, or use Chrome or Firefox. Alternatively, renaming the .zip file as .ipsw file should also work.
