Apple released iOS 13.4.1 to the general public yesterday, and as you might come to expect, this has a few implications for the jailbreak community. Obviously, the unc0ver jailbreak doesn’t support the new firmware, as it can only jailbreak iOS 13.0-13.3. Checkra1n users, on the other hand, should be in the clear following a new update to the jailbreak tool on Wednesday.

Checkra1n co-developer Jamie Bishop took to Twitter this evening to share that checkra1n v0.10.1 had been released. This new update incorporates support for iOS/iPadOS 13.4 & 13.4.1, enabling handsets susceptible to the checkm8 bootrom exploit (A7-A11) to be jailbroken even on Apple’s latest and greatest software updates:

Citing the change log posted on the official checkra1n website, checkra1n v0.10.1 brings the following changes:

Bug fixes

  • Fixes support for A7 devices
  • Fixes an issue in 12.4 which caused the device to panic and reboot on attempted shutdown
  • Fixes an issue that caused the keychain to lose new passwords
  • Fixes an issue which caused the GUI/ncurses to crash when used more than once
  • Fixes an issue where a userspace reboot won’t restart dropbear

Other changes

  • Added 13.4 and 13.4.1 support
  • Introducing kernel patch finder v2 – rewritten from the ground up for sanic speed
  • You can now quit from the webra1n interface

Known issues

  • The Apple TV 4K will produce a -20 error, even on a successful jailbreak Other known issues are available on our issue tracker.

Known issues

  • The exploit may not work as reliably on some devices, such as the Raspberry Pi Zero and Raspberry Pi 3.
  • When trying to jailbreak multiple devices, only the first attempt will succeed. Workaround: relaunch checkra1n after every jailbreak attempt.

If you’re using an earlier version of the checkra1n jailbreak, then we would recommend downloading and deploying checkra1n v0.10.1 whether you’re running iOS 13.4/13.4.1 or not. This is because the latest update to the tool brings the latest bug fixes and performance improvements along with support for a new firmware version.

As always, the latest version of checkra1n can be downloaded for free from the official checkra1n website. Moreover, you can utilize our step-by-step tutorial for jailbreaking with checkra1n if you’ve never used the tool before or need help using it.
