Apple stops signing iOS 12.1.1 beta 3, halting downgrades to a jailbreakable firmware

In an unfortunate plow of events this week, Apple appears to
have stopped signing iOS 12.1.1 beta iii for nigh or all iOS devices. Before last
night, this was the terminal jailbreakable firmware that could notwithstanding live downgraded
to via iTunes since Apple closed
the signing window for the official iOS 12.1.1-12.1.2 releases precisely one
month ago.

Hacker an unc0ver Pb developer Pwn20wnd confirmed the unsigning condition via Twitter inward the wee hours of the night, soon next upwards alongside reports maxim that it was notwithstanding beingness signed past times Apple for for sure devices. As expected, a duet of high-profile individuals such equally rootlessJB 3.0 developer Jake James as well as OsirisJailbreak12 creator GeoSn0w confirmed that the firmware wasn’t beingness signed for their devices:

A pop thread on /r/jailbreak further confirmed the circumstances.

The intelligence is unfortunate if you lot haven’t downgraded to a jailbreakable version of iOS 12 yet, but it won’t behave upon those who’ve already downgraded. Fortunately, the unc0ver jailbreak volition move only fine alongside iOS 12.1.1 beta 3; furthermore, the jailbreak tool is programmed to resist those annoying ‘beta expiry’ pop-ups, which way it should perform only equally it would on a regular unloose of iOS.

Given the nigh recent circumstances, the lowest firmware you lot tin mayhap downgrade to equally of this writing is straightaway iOS 12.1.3, and this firmware is non jailbreakable at the fourth dimension of this writing because all the latest exploits, including voucher_swap, v1ntex, v3ntex, as well as machswap are exclusively compatible alongside diverse iOS versions from iOS 11.0-12.1.2. Things could alter inward the hereafter if a safety researcher releases a novel exploit, but there’s no telling if or when that volition happen.

Wondering what you lot should produce now? We receive got the answers…

If you’re on iOS 12.0-12.1.2, thence you lot should remain where you lot are because you lot tin jailbreak your iOS device alongside unc0ver. If you’re on iOS 12.1.1 beta 3, thence you lot should also remain where you lot are because you lot also tin jailbreak your iOS device alongside unc0ver.

If you’re on iOS 12.1.3, thence remain where you lot are. Pwn20wnd has ever previously said that it’s best to remain on the lowest firmware possible when it comes to jailbreaking. That said, those on iOS 12.1.4 alongside whatever intention of jailbreaking are advised to downgrade to iOS 12.1.3 whenever possible such that if an exploit gets released, you’ll live inward skilful shape.

Now that iOS 12.1.1 beta iii isn’t beingness signed anymore, the
stakes for jailbreakability receive got only risen. That said, nosotros highly recommend that
novice jailbreakers avoid beta-centric jailbreak tools such equally the unc0ver
v3.0.0 pre-release until it comes out of beta as well as is officially released to the
public. We say this to ensure stability as well as to decrease your conduct a opportunity of having to
restore your device to a non-jailbreakable firmware.

In the meantime, those alongside jailbreak eligibility should practise due diligence to save their jailbreak-eligible state, as well as the residual volition only receive got to hold back as well as meet if whatever novel exploits are posted inward the future.

Are you lot deplorable to meet that Apple has unopen the signing window
for iOS 12.1.1 beta 3? Discuss inward the comments department below.
