Checkn1x 1.1.4 (checkra1n 0.12.1, iOS 14.* A10/A10X/A11)


What’s new

Highlighted changes

Adds an on-device alert to indicate checkra1n’s Safe Mode is active

Adds support for iBridge SSH from the same host

Partial support for the original HomePod (CLI only, tested to work with audioOS 13 and 14)

Bug fixes

Fixes an issue that would often cause Safe Mode to be entered on iOS 14.2 regardless of whether the user requested it or not

Safe Mode no longer loads 3rd-party LaunchDaemons

NVRAM is now unlocked on iOS 14.2 as well

Fixes an issue where jailbreaking an AppleTV fail on fresh tvOS installations

The bundled dd binary now has the entitlement required to access block devices

Fixes multiple memory leaks in early-boot binaries

Changes some GUI internals that should reduce the chance of exploit failure and GUI hiccups


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

A10/A10X devices on 14.3 and above as well as T2 devices on bridgeOS 5.1 and above will crash and reboot before reaching PongoOS

On A10/A10X devices running iOS 14, boot may sometimes hang in pongoOS. In that case, reboot the device and retry.

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


As soon as macOS boots it’ll take over the USB connection and disallow communication

Some users have reported checkra1n crashing when Chinese is set as the only system language. It is unknown whether any other language is affected.
