As a warning and a disclaimer, some users have been experiencing boot loop issues, so be cautious before you head over to the jailbreaking process. If you're okay with it, follow the instructions provided to you below.

Step 1: If you're on Apple's latest iOS 12 firmware that does not support unc0ver jailbreak, you can downgrade to iOS 12.1.1 beta 3, which for our luck, Apple is currently signing. Grab the iOS 12.1.1 beta 3 from here. If you're on a compatible iOS version, you're welcome to skip this step.

Step 2: Download the latest unc0ver 3.0.0 IPA. Next, you can download Cydia Impactor from here.

Step 3:  Now, on your iPhone or iPad, make sure that Find My iPhone is turned off along with the device passcode. Once you do this, connect your iOS device to your computer.

This means that after rebooting your iOS device, you will have to jailbreak it again through the unc0ver app. Furthermore, you will have to resign and sideload the unc0ver app again after every seven days. This is due to the fact that the Apple ID certificate used to sideload Cydia only lasts for seven days.
