About Cydia:

Currently Cydia is not included so it won't be that easy to install the jailbreak apps and tweaks. Avoid installing Cydia from unknown sources.

Cydia Substrate needs to be also updated for iOS 11 by saurik, so many jailbreak tweaks may not work.

Before Jailbreaking:

The jailbreak is semi-tethered, similar to the Pangu jailbreak for iOS 9.3.3 and Yalu Jailbreak for iOS 10 – iOS 10.2.

Make sure that you take a complete backup of your iPhone, iPad or iPod touch using iTunes.

Ensure that your device has enough battery level for the jailbreak process to complete.

Warning:

This is the first release candidate, so we would recommend readers to wait to get feedback before trying it yourself.

If you're new to jailbreaking then we would recommend waiting for a jailbreak that pre-installs Cydia. We'll keep you posted as soon as we have any further updates.

Jailbreak process: 

Step 1: Download LiberiOS Jailbreak and Cydia Impactor 

Step 2: Install LiberiOS IPA using Cydia Impactor

Step 3: Trust Developer Profile

Step 4: Run Jailbreak Process

Step 5: Wait for Jailbreak to Complete

If the jailbreak fails then you can report it on his forum.

How Does Semi-Untethered Jailbreak Work?

This is a semi-untethered jailbreak, which means that when your device restarts, the jailbreak will be disabled. You cannot use any jailbreak tweaks you installed and Cydia will crash when launched. To re-jailbreak, simply open the LiberiOS jailbreak app and perform the jailbreak again. Your device will then go back to the jailbroken state.

When Does the LiberiOS Jailbreak App Expire & How Do I Renew It?

If you are installing the LiberiOS app with a free Apple Developer account, it will expire after 7 days. So you have to re-install it via Cydia Impactor to extend it for another 7 days. The steps are the same as outlined above. Also note that you need the LiberiOS Jailbreak app only when you want to re-jailbreak your device after rebooting your iOS device, so even if it expires, the jailbreak will remain as is.
