Important information

This release is an early beta preview and as such should not be installed on a primary device. We strongly recommend proceeding with caution.

What’s new

• Fixed an issue where the Apple Watch would not receive notifications while jailbroken
• Improve reliability of entering DFU mode
• Fixed an issue where checkra1n could not be used on macOS 10.10

This beta adds an option to boot into no-substrate mode. To utilize this functionality, hold the volume-up button when the apple logo appears until the device finishes booting. From there you’ll be able to uninstall any tweaks causing you issues and reboot to get back to a normal jailbroken state.

Unsupported devices

checkra1n will eventually support all devices between the iPhone 5s and the iPhone X, however, this beta lacks support for the following devices:

• iPad Air 2
• iPad 5th Gen
• iPad Pro 1st Gen

Support for these devices will be added in a later release.

Support for the following devices is experimental, and may require more attempts than usual:

• iPhone 5s
• iPad Mini 2
• iPad Mini 3
• iPad Air

Reliability on these devices will be improved in future releases.

Unsupported platforms

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

Package managers

At the moment, checkra1n only supports installing Cydia. Support for other package managers is coming soon, and will not require a checkra1n update.
