Hacker and unc0ver lead developer Pwn20wnd cooked up a brand-new update for his renowned jailbreak tool and released it to the public on Sunday, officially bringing it up to version 4.3.1.
Pwn20wnd announced the latest update in a Tweet shared this afternoon, adding that it would introduce more than 30 bug fixes and stability improvements for jailbreakers:
A little while later, Pwn20wnd said the wrong version of the jailbreak was uploaded and that it had been fixed. Unc0ver co-developer Sam Bingner rebranded the proper version of the jailbreak to unc0ver v4.3.1 so that users could tell the difference:
Citing the change log on Pwn20wnd’s official GitHub repository, this unc0ver jailbreak update incorporates the following changes:
03/08/2020 – v4.3.1 was released for production with the following changes:
Make the following changes for the substitute code substitutor:
– Bumped version to 4.3.1 due to a Github bug causing an older file to be temporarily available
– Add support for rebooting the userspace for the first time in a jailbreak
– Add support for injecting to the entire userspace
– Add support for looking up or registering services from the sandbox with the cy: prefix for developers
– Reboot the userspace after jailbreaking
– Make major design changes to preserve stock system performance
– Fix random reboots, freezes, memory issues and any known problem that affected system services or apps
– Fix persistent software update blocker on iOS 13 (Works in the jailed state too)
– Fix a design problem that affected the Succession restore tool
– Automatically re-enable software updates when restoring RootFS
In a series of Tweets shared previously, Pwn20wnd said this update would resolve every known problem with system apps and services and that it would improve battery life substantially by addressing daemon issues that affected some users upon jailbreaking. That said, this is an update you won’t want to skip.
In case you missed it, unc0ver now supports all iOS 13.0-13.3 devices. Originally, supporting only A12(X)-A13 devices on iOS 13.0-13.3 with the help of Brandon Azad’s oob_timestamp exploit, a revised exploit dubbed time_waste by Jake James introduced support for A9-A11 devices that were already jailbreakable with checkra1n. This makes it possible to switch between checkra1n and unc0ver on supported firmware versions when needed, such as when a computer is out of reach.
