Following the release of iOS 11.4 last week, Apple has just stopped signing iOS 11.3.1, which means you can’t downgrade to iOS 11.3.1 anymore. This appears in response to the recent jailbreak news regarding iOS 11.3.1.

Apple usually stops signing old versions following the release of a new update. This is Apple’s way of ensuring that users can experience the most recent version of iOS and thus have the latest security as well as performance improvements.

During the WWDC 2018 keynote, Apple mentioned that the installation rate for iOS 11 has surpassed 81%. It is believed that maintaining such a high installation rate should have something to do with the frequent closure of the signing channel for the older versions.

As far as jailbreak concerned, apparently, Electra Jailbreak would soon support iOS 11.3.1, according to the official website of the jailbreak tool. Thanks to the Ian Beer, who have released tfp0 exploit that enables iOS 11.3.1 to be jailbreakable.
