Last chance to downgrade to iOS 12.1.1 as S0rryMyBad publishes details about iOS 12-centric kernel exploit

Apple officially dropped iOS 12.1.3 on Tuesday, and it wasn’t long after that security researcher @S0rryMyBad Tweeted a proof of concept (PoC) of the bug used to achieve an iOS 12 jailbreak at the TianfuCup PWN Contest last November.

On Wednesday, @S0rryMyBad followed up with the PoC he Tweeted by publishing a detailed blog post elaborating the ins and outs of his bug, including how it works and how to use it on iOS 12.1.2 and below:

Apple stopped signing iOS 12.1 yesterday, but you can still downgrade to iOS 12.1 beta 2

On Tuesday, Apple stopped signing the iOS 12.1 public release, preventing downgrades from iOS 12.1.1 or 12.1.2, which patched a variety of bugs and exploits that could potentially amount to something in the jailbreak community down the road.

Citing a Tweet shared this morning by hacker and unc0ver lead developer Pwn20wnd, Apple is still curiously signing iOS 12.1 beta 2, which means you could downgrade to iOS 12.1 beta 2 via iTunes if you tried:

Apple stops signing iOS 12.1, preventing firmware downgrades via iTunes

Apple officially closed the signing window for iOS 12.1 on Tuesday, a move that prevents all iPhone and iPad users from downgrading their handset’s firmware via iTunes to any version lower than iOS 12.1.1.

Apple released iOS 12.1.1 just under two weeks ago and followed up with iOS 12.1.2 yesterday afternoon, so it’s not very surprising that the company is halting downgrades to iOS 12.1. It’s somewhat typical for Apple to stop signing an older firmware version about two weeks after an update is released.

Apple highlights “Best of 2018” in its App, Books and iTunes stores

Apple this morning issued a press release, announcing the "Best of 2018." For those unfamiliar with the tradition, every year around this time, the company highlights popular content across its various media apps and stores. Now you can see these lists for yourself in their respective apps—Apple Music, Apple Podcasts, Apple Books and iTunes—but we've rounded up the top picks below.

Apple stops signing iOS 12.0.1, hindering downgrades from iOS 12.1

Apple stopped signing iOS 12.0.1 on Tuesday, a move that prevents all iPhone and iPad users from downgrading their firmware via iTunes to any version lower than iOS 12.1.

It’s been almost one full month since Apple publicly released iOS 12.1, signaling one of the Cupertino-based company’s longest firmware signing windows in recent memory; most windows only last for about two weeks.

Last chance to downgrade to iOS 12.0.1 for potential jailbreakability

Apple officially released iOS 12.1 to the public last week, and if history is anything to go by, then that means the Cupertino-based tech giant will soon close the gates for downgrades to iOS 12.0.1 via iTunes.

Apple generally closes the signing window for older firmware approximately 14 days after a new version is released, give or take a day. That said, if you’ve been thinking about downgrading back to iOS 12.0.1, then you should probably get a move on.

Apple is no longer signing iOS 12.0

On Monday, Apple stopped signing iOS 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 via iTunes.

The news shouldn’t come as much of a surprise since the Cupertino-based tech company released iOS 12.0.1 to the public just over two weeks ago. Apple typically stops signing firmware approximately 14 days after releasing a new version to facilitate software upgrades among its user base.
