Cupertino-based Apple Inc. has officially stopped signing its iOS 11.4 firmware approximately one week after releasing iOS 11.4.1 into the public domain. The move means that device owners are no longer able to downgrade from iOS 11.4.1 to another version of Apple’s mobile firmware.
The majority of iPhone and iPad owners who have been within Apple’s ecosystem for a decent period of time will be well aware of Apple’s commitment to continually updating and releasing new versions of iOS.
Tim Cook’s company dropped iOS 11.4.1 last week containing a plethora of bug fixes, under-the-hood enhancements, and overall improvements that should stabilize and correct any issues found with the iOS 11.4 release. With that release now find its way onto devices around the world, Apple has decided to stop signing iOS 11.4 final as well as iOS 11.4 beta 3, which will really only have a large effect on would-be jailbreakers looking to downgrade.
Most iOS device owners will see a new version of iOS, choose to upgrade as per Apple’s prompt, and then never look back. However, where jailbreaking is concerned, it’s always a wonderful situation if device owners have the opportunity to roll back their firmware should they need to do so. And with the Electra jailbreak supporting iOS 11.4 beta 3, some would-be jailbreakers have been taking the opportunity to take that backward step and liberate themselves using the aforementioned jailbreak. This internal decision by Apple relating to iOS 11.4 has now put an immediate stop to that process.
For those who aren’t interested in a jailbreak then iOS 11.4.1 is definitely an installation worth having. Apple introduced a number of new features with the release of iOS 11.4, including Messages on iCloud and AirPlay 2, which works harmoniously with updated HomePod hardware. iOS 11.4.1 doesn’t expose brand new features but it does do a very good job of streamlining that iOS 11.4 release and ensuring that iPhone, iPad, and iPod touch owners get the best possible experience across all supported hardware.
iOS 11.4.1 could also be the last version of iOS 11 to be released into the public domain ahead of an official public release of iOS 12. Apple is currently testing iOS 12 with developers and public testers. The next major release as far as Apple’s mobile platform is concerned could be the first public unveiling of iOS 12 this coming September.
