This release is a beta preview and as such should not be installed on a primary device.

What’s new

Other changes

• Add inital Apple TV 4K support
• Purge OTA updates on boot

• Properly handle situations where there’s no internet connection available while bootstrapping tvOS

If you are experiencing the -20, please rejailbreak with the no-substrate mode option checked in the app, and see if removing tweaks resolves your issue.

Known issues

Unsupported devices

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 Linux (eta son) and Windows, 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.
