iOS Jailbreaking: Checkra1n 0.12.0 released with support for iOS 14.2 & iOS 14.x jailbreaking on A10(X) devices + partial A11 support! taikhogame.com
Just 3 days after iOS 14.2 was released, the checkra1n folks already managed to jailbreak this new version of iOS and released checkra1n 0.12.0 but this version is much more than a compatibility update. This is because checkra1n 0.12.0 allows one to jailbreak A10(X) & A11 devices running iOS 14 with the former utilising a SEPROM exploit!
Checkra1n 0.12.0 released with iOS 14.2 support & iOS 14.x jailbreaking on A10 & A11 devices
For those who are out of the loop, checkra1n is a jailbreak that uses the unpatchable checkm8 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
- 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
- A ‘Quick Mode’ was added that allows the GUI to run on a timer thus requiring no button clicks to jailbreak a device
- Many issues were fixed including one that caused crashes at boot time, updates to PongoOS and other stuff
Which devices are supported by checkra1n 0.12.0?
The following devices are fully supported by checkra1n 0.12.0 on iOS 12.0-14.2:
- iPhone 6S, 6S Plus, 7, 7 Plus & SE
- iPad 5th, 6th and 7th generation
- iPad Air 2
- iPad Mini 4
- iPad Pro 1st generation (both 9.7-inch and 12.9-inch models)
- iPad Pro 2nd generation (both 9.7-inch & 12.9-inch models)
- iPod Touch 7th generation
- Apple TV 4 & 4K
- iBridge T2
On the other hand, the iPhone 8 (Plus) and iPhone X are only partially supported on iOS 14.0-14.2 as one can’t have a pass-code enabled although full support is retained on iOS 12.0-13.7. Apple A7 & A8 devices are supported on iOS 12.0-12.4.9 although checkra1n 0.12.0 doesn’t work with A7 devices when running on Linux.
