A new jailbreaking tool is already available for iOS 14, but the team behind the “Checkra1n” jailbreaking tool (version 0.11.0) says it only works on a limited number of devices. The jailbreak only works on devices powered by A9(X) chips and older.
checkra1n 0.11.0 is now available, adding support for iOS 14 on A9(X) devices and below.

Currently, the new version of “Checkra1n” works for iOS 14 and iPadOS 14 only on the following devices.
- iPhone 6s, 6s Plus, and SE
- iPad (5th generation)
- iPad Air 2
- iPad mini 4
- iPad Pro (1st generation)
- Apple TV 4 and 4K
In a statement accompanying the announcement of the software release, the team said that it needed “more time to work around a new security mitigation” before it could offer jailbreaking iOS 14 on newer devices.
In iOS 14, Apple added a new mitigation to SEPOS on A10 and above (except on Apple TVs and iBridge): if the device was booted from DFU mode and the Secure Enclave receives a request to decrypt user data, it will panic the device. Since checkm8 does not give us control over the Secure Enclave, this is not trivial to workaround. However, with the recently published blackbird vulnerability, we are able to get control of the Secure Enclave on A10 and A10X and disable this mitigation. Support for A10 and A10X devices is being worked on and is expected to be ready in the coming weeks.
The team said support for iPhone 8, iPhone 8 Plus, and iPhone X to “be addressed in a future statement.”
The new jailbreak was developed by the same security researchers responsible for last year’s “checkm8” exploit, which worked with nearly every chip made by Apple, offering a permanent, non-patchable jailbreak on hundreds of millions of iOS devices.
