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.

  • iPhone XS Max (Partial support)
  • iPhone XR (Partial support)

Pre-Requisites

  • 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.
