How to jailbreak iOS 12.0-12.5.7 with Chimera

In addition to the unc0ver jailbreak by Pwn20wnd, iOS 12 users have the option to use the Chimera jailbreak by the CoolStar-led Electra Team.

It’s worth noting that the Chimera jailbreak does not support Cydia or Cydia Substrate, and that it instead uses Sileo and libhooker as a part of its Procursus bootstrap for package management and tweak injection. That aside, it is the first public jailbreak tool to officially support A12(X) devices.

Chimera currently supports iOS 12.0-12.5.7 on A7-A11(X) devices as new as the iPhone X and as old as the iPhone 5s, however it only supports iOS 12.0-12.1.2 on A12(X) devices such as the iPhone XS, XS Max, and XR. In this tutorial, we’ll show you how to jailbreak your supported handset with the Chimera jailbreak tool.
