How to Use CheckRa1n 0.12.2

If you are about to liberate your iPhone, iPad or iPod touch from restrictions imposed on iOS by Apple for the first time, here you’ll find out how to use CheckRa1n 0.12.2 to jailbreak your supported device running on iOS 12 – 14.3.

Before you actually start CheckRa1n Jailbreak iOS 14.3, there are some preconditions for successful jailbreaking process completion. So, here they are:

  • Checkra1n Jailbreak Tool currently works only on macOS and Linux. The Windows version is in progress.
  • Since the CheckRa1n jailbreak is a semi-tethered tool, you need a computer to boot your jailbroken device if it will be powered off.
  • CheckRa1n Jailbreak Tool supports all 64-bit devices equipped with A5-A11 chips, which are iPhone 5S up to iPhone X with few exceptions: iPad Air 2, iPad (5th generation), and iPad Pro (1st generation).
  • iOS versions supported are from iOS 12.0 and up to the latest released iOS 14.3.
  • Cydia package manager is installed by default, but other package managers, such as Installer and Zebra, will be supported soon.

The CheckRa1n team says that their jailbreaking tool officially supports A8, A8X, A9, A9X, A10, and A10X devices running iOS or iPadOS 14 and higher. CheckRa1n Jailbreak Tool allows you to expect the same level of security you have on non-jailbroken devices. Here is the list of the devices this statement is applicable to:

  • iPhone 6s, 6s Plus, SE, 7 and 7 Plus
  • iPad 5th, 6thand 7thgenerations
  • iPad Air 2
  • iPad mini 4
  • iPad Pro 1st and 2nd generations
  • iPod touch 7

As for the newer devices equipped with A11 chips, CheckRa1n will jailbreak iOS 14.3 on these devices as well, which include iPhone 8, 8 Plus, and iPhone X. But there is one thing you should do to have your device jailbroken. You’ll have to turn on the “Skip A11 BPR check” option in the CheckRa1n app before you start the jailbreaking process. This way, the passcode on your jailbroken device will be turned off. This action is not recommended for most users as it affects authentication and security. However, this way developers can test their work on newer devices. Our hope is that the CheckRa1n team will find the way to bypass this step on A11 devices running on iOS 14.0 and higher.

Now, that you know how to use Checkra1n Jailbreak, let’s get started by following the steps below saying how to jailbreak iOS 14.3 using CheckRa1n 0.12.2.
