Downgrade iOS 10.2.1 to iOS 10.2 & Jailbreak Yalu – Tutorial!

Today, ensuing the recent iOS 10.2 (beta) jailbreak from hacker Luca Todesco, I opted to release an updated downgrade guide outlining how to essentially go back from iOS 10.2.1 to iOS 10.2 with the intention of being able to jailbreak. Whether you want to downgrade iOS 10.2.1 because your device is currently supported by the aforementioned Yalu jailbreak or because you plan on jailbreaking once your device is, the good news is that you can do so while retaining the majority of your data!

iOS 10.2.1 Downgrade: Full Disclosure

iOS 10 Downgrade
Important: While you’ll retain all app data, your text messages and non-iCloud saved notes will be deleted from your device, which is better than the alternative (having to restore from your last iOS 10.2.1+ backup, chances are good you don’t even have one).

With that said, let’s proceed with this incredibly simple downgrade method to get you back to the comfort and peace of mind iOS 10.2 offers (since it’s jailbreakable)!

Steps to Downgrade from iOS 10.2.1 Beta to iOS 10.2

iOS 10 Downgrade for Device

1. Obtain your devices corresponding iOS 10.2 IPSW via this service.

Note: If you’re at all confused, I highlight how to identify and download your iPhone, iPad or iPod’s iOS 10.2.1 IPSW in the above video.

2. Plug your device into your computer via a USB cable, launch iTunes (make sure it’s the latest version), and navigate to the primary device screen inside of iTunes.

3. Hold the Option (alt) key on Mac OS X or the Shift key on Windows and left click “Check for Update”. Point the popup window at your device’s iOS 10.2 IPSW; downloaded in the first step.

4. Refrain from interacting with your device until you receive the “Update Completed” notice. If you have a passcode, enter it and wait for the on-device consolidation to occur. After that, you’ll be on iOS 10.2!

That’s it, seriously! It only takes four basic steps to downgrade from iOS 10.2.1 beta to iOS 10.2 Watch the above video for a complete walkthrough.
