About a year ago, axi0mX released the checkm8 BootROM exploit effectively giving an un-patchable code execution at a low level exploit for devices up to the iPhone X & 8 (Plus) as the A11 SoC and below are vulnerable. This was thought to translate into eternal jailbreaks for all supported devices but Apple decided to throw a curveball with iOS 14 but not for all devices which has allowed the checkra1n team to jailbreak it on some older devices with more following!

iOS 14 jailbroken on some devices with the release of checkra1n 0.11.0 beta

Apple has decided to make jailbreaking iOS 14 quite a bit more difficult on some checkm8-vulnerable devices but the checkra1n team aren’t bowing down just yet! (Tweet)

Thanks to the checkm8-powered checkra1n jailbreak, iOS 14 has been jailbroken in a measly 6 days which is a throwback to the limera1n days early last decade when new iOS releases were jailbroken days after their release on vulnerable devices. However, while this is excellent news, it is soured quite a bit by the fact that checkra1n doesn’t support jailbreaking iOS 14 on all devices vulnerable to the checkm8 exploit with it leaving A10, A10X and A11 devices out for now bar the Apple TV meaning that only A8, A9 and A9X devices are supported.

According to a statement released by the checkra1n team (below), the reason behind A10-A11 devices being excluded for now is because Apple added a new mitigation in SEPOS (the Secure Enclave Processor’s firmware). This panics (i.e. crashes) the device if it is booted from DFU mode and a request to the Secure Enclave is made to decrypt user data. Thankfully, there is a silver lining to this as there exists a Secure Enclave vulnerability called blackbird which is publicly available and can probably be used to disable this mitigation on A10 & A10X devices. When it comes to A11 devices (iPhone X, iPhone 8 Plus & iPhone 8), things may be a bit more difficult and the checkra1n team will release another statement once more information becomes available.

Which devices can be jailbroken on iOS 14 using checkra1n 0.11.0 beta?

iOS 14 can be jailbroken as usual on A8(X) & A9(X) devices although some tweaks may be broken as the update was just released!

Currently, the following devices can be jailbroken on iOS 14 using checkra1n 0.11.0 beta:

• iPhone 6S, 6S Plus & SE
• iPad 5th generation
• iPad Air 2
• iPad Mini 4
• iPad Pro 1st generation (both 9.7-inch and 12.9-inch models)
• Apple TV 4 & 4K
  • While the Apple TV 4K is an A10X device, Apple’s added mitigation doesn’t affect it
• iBridge T2

Furthermore, the following devices are expected to become supported in the following weeks as they use an A10(X) SoC:

• iPhone 7 & 7 Plus
• iPad 6th & 7th generation
• iPad Pro 2nd generation (both 9.7-inch & 12.9-inch models)
• iPod Touch 7th generation

When it comes to devices using the A11 SoC, there is no clear indication on when support will be added meaning that if you have an iPhone X, iPhone 8 Plus or iPhone 8, it is imperative to stay on iOS 13 for the time being if you care about jailbreaking!
