iOS 11–11.1.2 full jailbreak released: supports all 64-bit devices

On Christmas Day, a full jailbreak of iOS 11-iOS 11.1.2 was released abroad, named LiberiOS, based on the vulnerability discovered by Ian Beer.

This jailbreak is applicable to all 64-bit iOS devices, that is, all phones from iPhone 5s to iPhone X, and tablets including iPad mini (2/3/4), iPad Air (1/2), all models of iPad Pro, etc.

However, this is not a normal jailbreak. Once the device is restarted or every 7 days, you need to go through the jailbreak process again.

Note that currently, Apple only issues verification for iOS 11.0.2 to iOS 11.1.2.

Preparation:

1. A developer account only needs to be registered at developer.apple.com or bound to a previous Apple ID, no fees are required.
2. Download the latest iTunes (address) and Cydia Impactor (address) on your PC or Mac.

Formal steps:

1. Connect the device to the computer (Win PC or Mac) with a data cable
2. Download the iPA file of LiberiOS (click here)
3. Run Cydia Impactor, drag the iPA file in, and follow the on-screen prompts to install it. During the installation, you will need to enter your developer account.
4. After successfully installing iPA, go to Settings-General-File and Device Management and set LiberiOS as trusted
5. Go back to the home screen, run LiberiOS, and click "Do It"
6. Wait a few seconds and the jailbreak will be completed.

Since Cydia has not yet been updated for iOS 11, it cannot be used even if the device is jailbroken.
