On Monday,Applestopped signingiOS 12.0, making it impossible to downgrade from iOS 12.0.1 to iOS 12.0. The move also compels those on iOS 12.0 to upgrade to iOS 12.0.1 when attempting a restore viaiTunes.
The news shouldn’t come as much of a surprise since the Cupertino-based tech companyreleased iOS 12.0.1 to the public just over two weeks ago. Apple typically stops signingfirmwareapproximately 14 days after releasing a new version to facilitatesoftwareupgrades among its user base.
Notably, this is the first time Apple has stopped signing any version of iOS 12. Apple justseeded iOS 12.1 beta 5 to developers earlier this afternoon, indicating that it’s getting closer to public release.
iOS 12.0.1 was a bug fix update for Apple’s latest and greatest mobile operating system, so no one should really be trying to downgrade to iOS 12.0. As for thejailbreakcommunity, this change makes no real difference as there haven’t been any public jailbreak releases for iOS 12 since the software updatefirst launched in mid-September.
Apple’s shift toward rapid iOS update releases has undoubtedly caused more strain on the jailbreak community. As Apple stops signing older versions of iOS, it forces hackers to shift their focus to newer releases, which often patch known exploits andsecurityvulnerabilities that are used in jailbreaking.
Apple is obligated to patch these vulnerabilities promptly to protect its consumers from rogue hacks, but it’s still unfortunate that Apple doesn’t give advanced users the choice to downgrade if they so wish to. This is why jailbreakers are frequently advised not to update their firmware when ajailbreak toolis under development.
