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 Substitute for package management and tweak injection. That aside, it is the first public jailbreak tool to officially support A12(X) devices.

Chimera currently supports all iOS devices running iOS 12.0-12.1.2, supports A7-A11 devices running iOS 12.1.3-12.3 beta, and supports A9-A11 devices running iOS 12.4. Notably, iOS 12.3 beta 6 is not supported. In this tutorial, we’ll show you how to jailbreak your Supported device with the Chimera jailbreak tool.
