Last week Apple issued iOS 9 to the general public, which, like iOS 8.4.1, patches the Untethered TaiG 8.4 Jailbreak. Considering Pangu recently publicized three new Jailbreak exploits that are exclusive to iOS 8.4.1, it’s conceivable that developers may issue an iOS 8.4.1 Jailbreak prior to the availability of an Untethered tool for iOS 9. In light of that interesting fact, I’ve opted to issue this new tutorial to aid those on iOS 9 in the rather simple process of downgrading iOS 9 to 8.4.1!
To preface, keep in mind that this guide is time sensitive; i.e. after Apple ceases signing iOS 8.4.1, it will no longer be possible to downgrade to said firmware. Moreover, as stated above, due to the uncertainty of which firmware the next jailbreak will be issued for, the choice to downgrade is ultimately up to you.
As a quick summary, this tutorial will assist you when downgrading iOS 9 to iOS 8.4.1 to possibly achieve a future Untethered iOS 8.4.1 Jailbreak on the following devices: iPhone 6, iPhone 6 Plus, iPhone 5S, iPhone 5C, iPhone 4S, Apple’s iPad Air 2, the iPad mini 3, original iPad Air, the Retina iPad mini 2, original iPad mini, iPad 4, iPad 3, iPad 2 and the 5th and 6th generation iPod touch models.
Brief iOS 8.4.1 Signing Window
Prior to downgrading, as previously mentioned, once Apple stops signing iOS 8.4.1 (as of writing this article the company is signing both iOS 9 and iOS 8.4.1), downgrades will no longer be possible, and you’ll simply be restricted to restoring to iOS 9.0.
As one concluding prelude, it’s highly recommended that you watch my above video in its entirety to ensure the success of your iOS 9.0 downgrade to 8.4.1.
How to Downgrade iOS 9.0 to iOS 8.4.1
Step 1. Confirm that you’ve downloaded all the necessary components for this tutorial, being the corresponding iOS 8.4.1 IPSW for your device and iTunes, both of which are available in the download section below.
Urgent Note: For this tutorial, you’re required to use the latest version of iTunes to ensure the success of your 9.0 downgrade.
Step 2. Disable ‘Find my iDevice’ (the name will be dynamic depending on your device) inside the iCloud segment of the Settings app to ensure that you can properly restore to 8.4.1 and launch iTunes to ensure that the tool properly recognizes your device.
Step 3. Depending on your computer’s OS, you’ll either be required to hold down the Shift or Option (Alt) key on your keyboard if you’re on Windows or Mac OS X, respectively. Left click “Restore”, point the pop-up at your device’s correct 8.4.1 IPSW and confirm the restore.
Urgent Note 2: You cannot restore from a backup (either iTunes or iCloud) that was created on a higher firmware – e.g. once you downgrade to iOS 8.4.1, your data accumulated on iOS 9 will not be restorable. Either use an older backup or sign in to iCloud to retrieve as much information as possible; the latter option won’t retrieve as much data, but it’s better than nothing.
Jailbreak iOS 9 and iOS 8.4.1 Update after Downgrade
Remember to take advantage of this loophole while Apple is still signing iOS 8.4.1 to ensure that you can Jailbreak on iOS 8.4.1, provided a new solution is released. The above video will walk you through the latest developments on the Jailbreak scene.
