If you have an arm64 iOS device running iOS 16.0 all the way up to iOS 16.6.1, you can now jailbreak with a brand new jailbreak tool called Def1nit3lyN0tAJa1lbr3akTool (Definitely Not A Jailbreak Tool).

Despite its name, this is a jailbreak tool compatible with all arm64 devices (A11, A10, etc.) with tweak support and Sileo Package Manager.

This jailbreak tool seems to be based on various components such as the KFD exploit (Kernel File Descriptor), Dopamine Jailbreak, kfund, etc.

Jailbreak compatibility

According to the developer, this jailbreak was successfully tested on the following devices and iOS versions:

• iPhone X:
  • iOS 16.6.1
  • iOS 16.6
  • iOS 16.6 Beta 1 (20G5026e)
  • iOS 16.5.1
  • iOS 16.5
  • iOS 16.4.1
  • iOS 16.3.1
  • iOS 16.2
  • iOS 16.1.2
  • iOS 16.1.1
  • iOS 16.1
  • iOS 16.0.2
• iPhone 8
  • iOS 16.6.1
  • iOS 16.6 Beta 1 (Build 20G5026e)
  • iOS 16.5
  • iOS 16.4
  • iOS 16.1.2
  • iOS 16.0
• iPad 6
  • iOS 16.5

Still, you may try it on other arm64 devices and iOS combinations as all arm64 devices are supposed to be supported according to the release log.

For now, you must compile the jailbreak using Xcode or install the pre-built IPA file using TrollStore. According to the developer, sideloading breaks something currently (AltStore, Sideloadly, etc.)

How to install Def1nit3lyN0tAJa1lbr3akTool

You currently have two options available if you want to use this jailbreak tool. You can either compile it yourself from the source code, or you can sideload the already available IPA file using TrollStore.

Here’s how you can do both of these methods.

How to compile/build Def1nit3lyN0tAJa1lbr3akTool

If you want to compile it yourself, you need the following prerequisites:

• Xcode
• macOS
• make
• The Bootstrap

This is a normal Xcode project so it compiles like any other project, however, some changes need to be made depending on what iOS version you have.

For iOS 15.7

Technically this jailbreak may work on iOS 15.7 as well, so if you are building for iOS 15.7, you need to run the following command in every subdirectory of basebin/.

TRUSTCACHEVERSION=1 make

Then compile the application with Xcode by opening the project, selecting your device (connected via USB and unlocked), and pressing the PLAY icon to compile.

For iOS 16

If you are compiling for iOS 16, you need to run the following command in every subdirectory of basebin/.

TRUSTCACHEVERSION=2 make

Then compile the application with Xcode by opening the project, selecting your device (connected via USB and unlocked), and pressing the PLAY icon to compile.

How to install Def1nit3lyN0tAJa1lbr3akTool using TrollStore 2

The easiest way to get the jailbreak installed is using TrollStore 2.

If you already have TrollStore installed, you can simply download the IPA file for Def1nit3lyN0tAJa1lbr3akTool from the button below on your device, then simply open it in TrollStore.

Please follow the steps below to install it in TrollStore 2:
