Following the release of a minor fix update in iOS 11.3.1 last week, Apple has stopped signing iOS 11.3 firmware.
The inevitable has happened, and if you haven’t upgraded or downgraded to iOS 11.3 yet, you can no longer do so on your iPhone or iPad as that particular firmware is no longer being signed.
As you may already know, Apple routinely stops signing older versions of software updates after releasing new ones come out in order to encourage customers to keep their operating systems up to date. The device owners who have updated to the latest iOS 11.3.1 will no longer be able to revert back to earlier versions of iOS, like iOS 11.3.
From jailbreak perspective, Google’s Ian Beer releasing his POC which is applicable to iOS 11.3 firmware after Apple patched it in iOS 11.3.1 last week. Unfortunately, there’s no proof or confirmation as of yet of it being used in the future public jailbreak. But the possibility is always there given the fact that Beer’s previous exploits have been used to create public jailbreak tools like Electra and others.
It’s highly recommended you, readers to downgrade to iOS 11.3 while they could if they were to have any chance of having an iOS 11.3 jailbreak in future.
Coming back to iOS 11.3.1 update, it was mainly launched to fix an issue in iOS 11.3 which was causing iPhone 8 and iPhone 8 Plus devices with third-party screen replacements to have unresponsive displays. With iOS 11.3.1 release, Apple fixed the issue, alongside also patching some minor bug fixes and adding critical security patches, such as “Crash Reporter” one by Google’s Ian Beer.
So, iOS 11.3.1 is now the only version of iOS 11 available to download and can be installed on iOS devices by the general public, but developers and public beta testers can download iOS 11.4, an update that is currently being beta tested. We’ll keep you updated on all the latest from jailbreak world. Stay tuned for more.
