Checkra1n 0.12.2 Jailbreak Update Released, Here’s What Is New

Checkra1n 0.12.2 jailbreak update has been released. Here’s what is new in update of iOS, iPadOS and tvOS jailbreak tool.

The extremely popular checkm8-based Checkra1n jailbreak has been updated to version 0.12.2 and comes with a number of important changes.

The Checkr1n team took to Twitter to announce the release, confirming that the latest deployment fixes some “LaunchDaemon issues” on A10/A10X devices. Rather than ushering in the New Year with celebrations, the team was quite clearly hard at work and also thought it worthy to mention that this latest version also enables USB on Apple TV 4K.

The official changelog for the Checkra1n beta v0.12.2 release is as follows:

What’s new

Highlighted changes

  • Enables USB on AppleTV 4k during normal system operation

Bug fixes

  • Fixes A10 and A10X devices crashing when trying to jailbreak on iOS 14.3 or higher
  • Fixes an issue where some LaunchDaemons were loaded on platforms where they should not have been

Notes

  • A11 devices on iOS 14.0 and above require removing the passcode and enabling “Skip A11 BPR check” in the options. This is not recommended, but it’s there.

Known issues

  • checkra1n does not currently work on Apple Silicon Macs
  • A7 devices will currently not work with the Linux version
  • The exploit may not work as reliably on some devices, such as the Raspberry Pi Zero and Raspberry Pi 3
  • Linux GUI build when using CLI mode doesn’t support auto assertion of DFU mode on advanced Apple TV 4k breakout boards
  • bridgeOS:
    • If you disconnect the cable, then as soon as macOS boots it’ll take over the USB connection and disallow communication with the T2
  • Some users have reported checkra1n crashing when Chinese is set as the only system language. It is unknown whether any other language is affected.

Unsupported platforms

This beta is only available for macOS and Linux. Work is ongoing to support Windows, which will be added in a later release.

Package managers

At the moment, checkra1n only supports installing Cydia. Support for other package managers, including Zebra and Installer is coming soon and is expected within the coming weeks.

The release notes also quite clearly stipulate that this is a beta previs, and, as such, should not be used and installed on primary devices. It’s very likely based on previous experience that it will be stable but the warning is there for a reason.
