Checkra1n 0.12.0 released with iOS 14.2 support & iOS 14.x jailbreaking on A10 & A11

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
