The latest beta of Unc0ver is out with iOS 12 – iOS 12.1.2 jailbreak support. What’s even better is that it has Cydia and Substrate support meaning you can jailbreak your iPhone and start installing your favorite tweaks right away. Confused as to how you can jailbreak your iPhone or iPad though? Follow this guide then.

The steps to jailbreak an iPhone or iPad running iOS 12 – iOS 12.1.2 using unc0ver is actually pretty simple. It is just a matter of downloading the app and letting it do its job properly.

Compatible Devices

For now, the latest beta of unc0ver 3.0.0 supports the following devices:

  • iPhone 5s
  • iPhone 6
  • iPhone 6 Plus
  • iPhone 6s
  • iPhone 6s Plus
  • iPhone 7
  • iPhone 7 Plus
  • iPhone SE
  • iPhone 8
  • iPhone 8 Plus
  • iPhone X
  • iPhone XS (Partial support)
  • iPhone XS Max (Partial support)
  • iPhone XR (Partial support)
  • 2018 iPad Pro (Partial support)
  • iPad Air
  • 6th gen iPad

Partial support for iPhone XS, iPhone XR, and 2018 iPad Pro lineup means that while you will be able to jailbreak these devices, you won’t be able to install Cydia on it right now. That should change once Saurik gets around to updating Cydia for A12 devices.


  • Make sure that no iOS 12 OTA file is downloaded on your iPhone or iPad. Delete it from Settings -> Storage and then proceed to reboot your device before attempting to jailbreak it
  • While Cydia and Substrate compatibility is there, some repos might not work due to an iOS 12 bug
  • To prevent future iOS 12 OTA updates from being downloaded on your device, you can install the tvOS 12 profile on it
  • Make sure to create a backup of all important data on the device

Warning: Some of our readers have reported that they are facing boot loop issue. So we would recommend caution before proceeding.

If your iPhone or iPad is running iOS 12.1.4, you can downgrade it to iOS 12.1.1 beta 3 as its still being signed by Apple.
