Historically, jailbreaking an iPhone has been a complicated task. Every time jailbreakers manage to punch a hole in Apple’s iOS, the tech company seals them with the next update. Due to this, existing iPhone jailbreaks are only available on increasingly specific builds. Recently, it was found that you can use a rooted Android phone to get around Apple’s protections in a way that's far simpler than previous options.
To start, you’ll need to root (another word for jailbreaking) your Android phone. Be sure you have adequate security to protect your devices from online threats, as you’ll lose developer support once you root your Android. This is the same for any jailbroken iPhones. Then connect the two phones, and to do this you'll need to pick up a converter as iPhone cables are only compatible with other Apple devices.
Posted by Reddit user stblr, this method enables any iOS device capable of running checkra1n to be connected to any Android device with a terminal app and root access. Through the Android phone, this jailbreak will take advantage of a flaw in Apple’s hardware, as opposed to the iOS software that most Apple jailbreaks target. Every iPhone model from the 5S to the iPhone X can use make use of this hack.
Jailbreaking Your Phone and Possible Risks
Once you have everything set up, download the Linux checkra1n binary with your Android’s corresponding µarch and place them into an execution-enabled directory. Then, connect the two phones and open your Android device’s terminal app to gain root access. Once your iPhone is connected, place it into DFU mode and watch the USB ID, it should go from 05ac:12a8 to 05ac:1227. When it does, run Checkra1n in CLI mode, and you've jailbroken your phone.
With the jailbroken phone, you’ll be able to customize your experience in ways not usually available. Over the years, Apple has removed hundreds of applications from its store and jailbreaking can make running these possible. However, once you do jailbreak your phone, you’ll be disqualified from any warranties for your device. Therefore, it might be smart to wait until the protected period has passed before doing this. You’ll also be unable to download any future software updates, so you will have to look elsewhere for any additional features. Jailbreaking isn’t for everyone, but it’s a good option for those who want more control over their devices, and as this process isn't reliant on the device’s hardware, the method will work on all iPhones running iOS 12.3 and up.
