For those who are out of the loop, checkra1n is a jailbreak that uses the unpatchable checkm8 (http://wololo.net/2019/09/27/ios-devices-axi0mx-releases-checkm8-an-unpatchable-bootrom-exploit-allowing-for-jailbreaks-on-every-fw-downgrades-dualbooting-and-more-exploit-works-on-a5-a11-devices-including-the-iphone-x/) exploit which leverages vulnerabilities in the BootROM of affected devices. These affected devices, which essentially have a jailbreak entry point forever, include all devices containing the A7-A11 SoC although there have been successful efforts to port the exploit to older devices with A5 & A6 SoCs which did not previously have a public BootROM exploit available.
With checkra1n 0.12.0, the team behind the jailbreak managed to introduce quite a few important features namely:
Official support for both iOS 14.1 & iOS 14.2
Checkra1n 0.11.0 worked on iOS 14.1 unofficially but not on iOS 14.2
Support for jailbreaking iOS 14.x on A10 & A10X devices which include the iPhone 7, iPod Touch 7th generation, iPad 6/7th generation and iPad Pro 2nd generation (10.5″ & 12.9″)
This was achieved through the utilisation of a SEPROM exploit as Apple decided to add some mitigations in SEPOS on A10 & A11 devices that interfered with jailbreaking (https://wololo.net/2020/09/22/ios-jailbreaking-news-ios-14-jailbroken-with-checkra1n-for-a9x-devices-and-below-a10x-devices-will-be-jailbroken-in-the-coming-weeks-with-the-fate-of-a11-ones-unkown/)
Partial support for jailbreaking iOS 14.x on A11 devices, namely the iPhone 8 (Plus) & iPhone X, was introduced
The support is partial because it requires the device NOT to have a pass-code for it to work meaning that devices become less secure! However, we might see some jailbreak tweaks that allow for some form of pass-code in the lock screen although these would obviously not be as safe as the real deal especially since biometrics would still be unusable
To jailbreak A11 devices on iOS 14.x, one has to enable the ‘Skip A11 BPR check’ in the Options menu
