Downgrade iOS 12.4.1 to iOS 12.4 – iPhone and iPad

August 27, 2019

This is the guide to downgrade iOS 12.4.1 to iOS 12.4. iPhone and iPad owners can still Jailbreak iOS 12.4. The iOS 12.4.1 cannot be Jailbroken at the moment.

Apple just released the iOS 12.4.1 update. The new update patches the loophole that led to the Jailbreak of iOS 12.4. The iOS 12.4 was Jailbroken about 10 days back. Previously, Apple patched a loophole in the iOS 12.2 and released the iOS 12.3 with a fix. The iOS 12.3 was unjailbreak-able. Accidentally or mistakenly, Apple unpatched the same bug in the iOS 12.4 update which caught the eye of Pwn20wnd. The developer was quick enough to update his Unc0ver tool to support all iPhones and iPads on the latest signed version of iOS.

The news of Jailbreak was seen as a security threat by all the privacy-concerned users. Billions of devices were put on risk as this bug allowed a third-party application to access the system files of iOS. The iOS 12.4.1 is Apple’s take on this flaw. Surprisingly, Apple has thanked Pwn20wnd in the acknowledgments of iOS 12.4.1. Previously, Pwn20wnd thanked Apple for the development in iOS 12.4 which allowed Jailbreak. It looks like both Apple and Pwn20wnd are taking a jab at each other.

Downgrading to iOS 12.4

Now, if you are planning of updating to iOS 12.4.1, remember that you will not be able to Jailbreak the iPhone anymore. Those of you who have already updated to iOS 12.4.1, but want to go back for the sake of Jailbreak, they can downgrade now. Also, the users who upgraded for the sake of checking the new version, but don’t want to stick to it, they can downgrade too. The downgrade is temporarily possible because Apple is still signing the iOS 12.4. Once Apple stops signing it, you will not be able to downgrade it.

This means that you can Jailbreak your iPhone/iPad only as long as Apple is signing the previous version. Jailbreak is something that you don’t see every other day. Apple’s foolproof security patches make it nearly impossible to Jailbreak iOS. The chances of seeing a new iOS version getting Jailbroken are once in a blue moon. It’s only a matter of time until the term Jailbreak becomes history for a while once again. Downgrade iOS 12.4.1 to iOS 12.4 and enjoy Jailbreak while you can.
