Download rootlessJB jailbreak for iOS 12-12.1.2

rootless jailbreak has just been released for iOS 12.0-12.1.2 users. While the jailbreak tool is still in early stages, you can get started right now by installing it on your iPhone or iPad.

What is rootlessJB?

rootlessJB is an iOS 12.0-12.1.2 jailbreak based on Brandon Azad’s voucher_swap exploit. It is developed by the renowned security researcher Jake James.   

As opposed to a “root” jailbreak such as unc0ver or Electra, a rootless jailbreak only has read and write permissions to the var subdirectory.

A “root” jailbreak, on the other hand, has full read and write-level access to the entire root filesystem of an Apple device. 

iOS 12.1.2 jailbreak

Despite offering limited support, rootlessJB is currently the only iOS 12 jailbreak tool with tweak injection capability.

Although Brandon’s exploit supports A12 devices (iPhone XS, XS Max, and XR), they are incompatible with rootlessJB. If you have a compatible A9-A11 device, follow the tutorial given below.

The voucher_swap exploit has a solid success rate. 

It almost always puts your device in the jailbreak state on the very first try. However, if it doesn’t work the way it’s supposed to, simply restart your device and enable Airplane mode before running the app again.

Checking jailbreak status (optional)

This jailbreak tool is very “barebones” at the moment and it doesn’t notify the user about the jailbreak state of the device.     

If you want to ascertain that your device is jailbroken, you must SSH into your iPhone or iPad and check whether or not it succeeds.         

Future development

Here’s the full list of improvements that you can expect from this jailbreak in the future –

  • SSH from device
  • Sandbox patches
  • Better tweak patcher
  • Fix app installation
  • A12 devices support
  • Fix preference loader
  • Package installer (Cydia replacement)
