An unpatchable bootrom exploit called "checkm8" works on all iDevices up until the iPhone X irrespective of whether they run iOS 12 or iOS 13 and makes them jailbreakable for life.

Now Checkra1n Jailbreak has been released for all A5-A11 iPhone, iPad and iPods. Checkra1n 0.9.7 added support for jailbreak iOS 13.3. iOS 13.3.1 beta support will be added soon.

I will show you guys how to take advantage of Checkra1n to Jailbreak iDevice for App analysis. First you have to download Checkra1n and install it on a Mac. Now you\re ready to go.

It will guide you to get your iDevice into Recovery mode.

Next is the DFU mode. Don't worry it's easier than you think. Just relax and follow the steps. Everything will be ok~

Take a look at your iDevice and you will know that it's been jailbreaked without fail.

Once completed you will see an icon "checkra1n" on your iDevice.

Guess what? Now you could install tools you need from Cydia and extract data from this iDevice as you wish.
