Pwn20wnd officially released unc0ver v4.2.0 to the general public Tuesday afternoon after several internal beta testers had teased the jailbreak working on A8X-A11 devices running iOS 13.0-13.3 earlier in the day.

The hacker announced the new update, along with some vital information, just this afternoon via Twitter:

Citing the change log on Pwn20wnd’s official GitHub page, unc0ver v4.2.0 incorporates the following changes:

02/25/2020 – v4.2.0 was released for production with the following changes:

 – Fix issues with system services on A12-A13 (i.e. iMessage notifications)
– Add iOS 13.0-13.3 support for A9 8X-A11 devices
– Fix temporary freeze after the jailbreak completed alert

Important Notes:

– You must reboot in order to install this update if you are already jailbroken
– Pwn20wnd’s substitute bootstrap tooling is used on A8X-A11 devices running iOS 13.0-13.3 for battery saving features, improved performance and compatibility reasons
– There is no particular reason to switch to the unc0ver jailbreak if you are already running the checkra1n jailbreak (Other than the convenience of being able to re-jailbreak your device without a computer)
– Your jailbreak apps and tweaks will be preserved when switching from the checkra1n jailbreak for A8X-A11
– You can switch back to the checkra1n jailbreak while preserving your jailbreak apps and tweaks but you will need to manually install Cydia Substrate from Cydia after switching back
– All devices running iOS 13.0-13.3 are now supported
– The connected Apple Watch may re-sync after jailbreak. It will take around a minute or two and it won’t touch your data

The single most significant change in this update is the support for A8X-A11 devices running iOS 13.0-13.0. Previously, the jailbreak only supported A12(X)-A13 devices running these versions of iOS. This now makes it possible to jailbreak any iOS 13.0-13.3 device with unc0ver, and furthermore, it can be used to re-jailbreak a device that was previously owned with checkra1n if you are unable to access a computer to deploy the jailbreak. The only exception to this rule is a device running iOS 13.3.1, as unc0ver does not support this version of firmware.

It’s worth noting that there’s no particular advantage to switching from checkra1n to unc0ver unless you’re stuck without a computer. If you do this and then decide later down the line that you want to use checkra1n again, then you will need to manually reinstall all of your jailbreak tweaks and extensions. Doing this isn’t necessary if you’re permanently switching to unc0ver, however.

If you’re already using an older version of the unc0ver jailbreak and you wish to update, or you wish to use it for the first time, you can download it from the unc0ver.dev website any use any of the following installation methods to use the unc0ver jailbreak:
