Apple stops signing iOS 9.0.2 rendering downgrade from iOS 9.1 impossible

Apple has finally stopped signing all versions of the jailbreak-able iOS 9.0.2 firmware for iPhone, iPad, and iPod Touch. Just a little over a week of the release of iOS 9.1 software update, Apple closes its signing window for iOS 9.0.2 firmware rendering it impossible to restore on any iPhone, iPad, or iPod Touch. This signing window’s closure makes it impossible to downgrade iOS 9.1 to iOS 9.0.2, which was the only jailbreak-able version.

For those who missed the news, with the release of iOS 9.1, Apple patched two vulnerabilities used by the team Pangu in their iOS 9.0.2 – iOS 9 Pangu jailbreak, effectively rendering it useless for iOS 9.1. Jailbreakers’ only hope was Apple keep on signing iOS 9.0.2 so they can downgrade from iOS 9.1 and re-jailbreak with Pangu jailbreak, which is no longer the case now.

Now that the signing window for iOS 9.0.2 has been closed by Apple, it greatly affects the jailbreak users. With downgrading option not available, jailbreak users must now be careful to not accidently update to iOS 9.1 or install any jailbreak tweak that may put their device in a reboot loop forcing them to restore it.

Apple released iOS 9.0.2 a month ago. iOS 9.1, which was released about a week ago, brings a host of new changes, enhancements, and bug fixes. It also brings 150+ emoji characters to iOS devices, enhancements to Live Photos, new wallpapers, and numerous improvements.

With iOS 9.0.2 signing window close, iOS users can now restore only the iOS 9.1 software version. And you cannot jailbreak iOs 9.1 as no team has released a tool for that.
