Less than a week after the public release of iOS 14, the checkra1n jailbreak tool has already received support for the new version. However, there is one caveat.
The news appeared on the checkra1n team’s Twitter page. After that, the hacker Luca Todesco commented on it.
Checkra1n v0.11.0 supports iOS 14, but only on devices with A9 (X) processor and older. Support for newer devices will appear in the future, but so far it is not ready. This is due to the fact that Apple has made it difficult to use the checkm8 exploit on new devices.
Checkra1n team explained the situation:
In iOS 14, Apple added a limitation for A10 and newer devices. If, after starting the device in DFU mode, the Secure Enclave system receives a request to decrypt user data, the system will start an alarm. Since the checkm8 exploit does not provide control over the Secure Enclave, the solution cannot be simple. However, thanks to the recently published blackbird vulnerability, we were able to gain control of the Secure Enclave on A10 and A10X devices to remove the restriction. We are already working on supporting these devices. Everything will be ready in the next couple of weeks.
The checkm8 exploit cannot be fixed with a system update, but Apple can always make it harder to break into a system. This is exactly what the company did in iOS 14. However, this does not completely rule out jailbreak. It just needs more time.
It is not known how soon checkra1n will receive support for the new version on newer models. Support for A10 and A10 (X) devices is coming in the coming weeks. A11 device support will take longer.
The openness of the checkra1n team should be appreciated. It’s nice that we are kept informed of the work on support for iOS 14. We were not promised anything concrete, but now it is at least clear that the work is in full swing.
Checkra1n jailbreak supports the following iOS 14 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
- iBridge T2
Support for these devices will appear in the coming weeks:
- iPhone 7 and 7 Plus
- iPad 6th and 7th generation
- iPod touch 7
- iPad Pro 2nd generation
Nothing is known about support for the following devices:
- iPhone X
- iPhone 8, 8 Plus
If you have a new device and have already upgraded to iOS 14, then for now you have the option to downgrade to iOS 13.7. There is no jailbreak for iOS 13.7 yet, but it’s always better to stay on older versions of the system. This increases your chances of getting a jailbreak in the future.
As usual, the new version of the checkra1n jailbreak can be downloaded from the official website. Our instructions will help you with installation:
