This wikiHow teaches you how to jailbreak your iPhone using Unc0ver and Checkra1n. Both tools are easy to use and work on most newer iPhones. Unc0ver is one of the few tools that can jailbreak the most recent versions of iOS (iOS 11 through 13). Checkra1n offers preliminary support for iOS 14 on some devices. Jailbreaking allows you to install apps and tweaks that aren't allowed in the App Store, which gives you more control over your iPhone. Be aware that Apple does not recommend jailbreaking and may not provide you support after doing so. Also, make sure you back up your iPhone data before jailbreaking.

Steps

Using Checkra1n for Mac

Make sure your iPhone is compatible. Checkra1n works on iPhone 5s through iPhone X models running iOS 12 through iOS 13. For iOS 14.0 (not 14.1), Checkra1n currently offers preliminary support for iOS 14 and only works for iPhone 6s, 6s Plus, SE, iPad 5th generation, iPad Air 2, iPad mini 4, iPad Pro 1st generation, Apple TV 4 and 4K, iBridge T2. Support for more iPhone and iPad models should be added in the coming weeks.

Go to https://checkra.in/releases/0.11.0-beta in a web browser. This is the official website for Checkra1n. Checkra1n is a semi-untethered jailbreak. This means that it will only work until your iPhone or iPad is rebooted. Once it is rebooted, you will need to use the Checkra1n app on your Mac or Linux computer to re-activate the jailbreak.

Scroll down and click Download for MacOS or for whichever version of Linux you are using. This downloads the install file for Checkra1n.

Open the install file. You can open it directly from your web browser or your Downloads folder. Follow any instructions needed to install the file. Especially on Linux. On Mac, just drag the Checkra1n icon into your Applications folder.

Connect your iPhone to your Mac. Use the lightning cable that came with your iPhone to connect it to a free USB port on your Mac or Linux computer.

Open Checkra1n. It has an icon that resembles two Chess pieces. Click the icon in your Applications folder to open Checkra1n. Make sure you iPhone is detected by Checkra1n when it opens.

Click Start. It's in the lower-right corner of the Checkra1n app. This begins the jailbreak process. If you are running an unsupported iPhone model, you can still try to install the checkra1n jailbreak on your device. Just be aware that it might not work properly. Proceed at your own risk. To allow it to install on an unsupported device, click Options and then check "Allow untested iOS/iPadOS/tvOS versions".

Click Next. This puts your iPhone or iPad in recovery mode. You will see an image of a lightning cable on your iPhone screen.

Read the instructions and click Start. You need to put your iPhone in DFU (Device Firmware Update) mode for this jailbreak to work. Read the instructions on the computer screen to learn how to do that. On most supported iPhones, you press and hold the Power button (top right corner) and the Home button (below the screen) at the same time. Read the instructions and then click start.

Follow the instructions to put your device in DFU mode. Press the home and power button at the same time when prompted.

Release the power button. Continue to hold the Home button, but release the power button when prompted. This will put your iPhone in DFU mode. You will see the Apple logo with the Checkra1n logo appear on your iPhone's screen. You will also see some text appear on the screen. When it is finished, the jailbreak will have been applied. If you open the Checkra1n app on your iPhone, it gives you the option to install Cydia, the unofficial app store for jailbreak apps and tweaks.
