What you need to know
- Checkra1n is the newest jailbreaking tool for iOS.
- It's an update to the Checkm8 bootrom exploit and works on iOS 12.3 onwards.
- You can now use an Android device as the tether when you jailbreak.
The latest jailbreaking tool for iPhone, Checkra1n, allows users to jailbreak an iOS device using Android.
As reported by Cult of Mac:
Checkra1n, the newest jailbreaking tool for iPhone, has some big advantages of its predecessors. It's the first that can successfully crack iOS 13. It works across system updates. And it's the first that allows you to jailbreak your iPhone using an Android device.
Still in beta for now, but very much a working tool, Checkra1n supports a whole host of iPhone and iPad models, and can jailbreak iOS 12.3 and up. It's based on the Checkm8 bootrom exploit that has been used in previous cracking tools, and it brings some nice improvements.
The downside to Checkra1n is that it's a tethered jailbreak. That means every time you reboot your iOS device, you must run Checkra1n to jailbreak it again. Now that the tool works on Android, however, it's easier than ever to do that on the go.
Now, it's obviously important to remember that jailbreaking comes with all of the usual risks, so if you're thinking of trying this you should definitely make sure you know what you're doing.
As the report notes, to jailbreak an iPhone using Checkra1n, you just download the tool, put your iPhone/iPad into DFU mode, and let Checkra1n do the rest. It's available on macOS (Windows support is on the way), and more importantly, Linux, which means it can now be tweaked to run on Android:
Using Checkra1n on an Android device is a rather lengthy, but not extremely complicated process. Full instructions on how to do it, and details on the setup you'll need, can be found on Reddit. Is it worth the effort? It is if you need to jailbreak anywhere.
As the report notes, using an Android device means you can jailbreak on the go without a Macbook or a desktop Mac tying you down.
*Jailbreaking should not be undertaken lightly. You risk losing out on future iOS updates, voiding your phone's warranty, reducing your phone's security and flat-out bricking your device(s). *
