What is Chimera Jailbreak?

Chimera is the first iOS 12 pwnd jailbreak tool to not only feature a CoreTrust bypass so that binaries don't need to be resigned, but to also support for all A7/A8/A9/A10/A11/A12 devices, including iPhone Xs, iPhone Xr, and the newest iPads. Chimera doesn't tamper with user files, making it safer than alternatives.

Chimera jailbreak tool for iOS 12 - iOS 12.2

On 7th April 2020, @coolstar released Chimera13, a jailbreak project with the goal to build a complete jailbreak for iOS 13.0 and higher in Swift (though C and ObjC are fine where needed). Currently, this GitHub project gives only the root shell via SSH.

Switch easily between different exploits (machswap2, voucher_swap, sockpuppet) to jailbreak your system. If you have a problem with jailbreaking the device there is also an option to disable tweaks temporarily. Restore your root filesystem to the state before jailbreak, if needed.

Chimera Jailbreak supports iOS 12.1.3 - iOS 12.4 on A7 - A11 devices.
A12 - A12X devices are supported only on iOS 12.0 - iOS 12.1.2.

If you are trying to restore to an unsigned version of iOS, Chimera Jailbreak allows you to set a nonce that can be used to downgrade or upgrade iOS version with saved SHSH blobs. Find more information on how to use futurerestore tool, save blobs from your iPhone, or download IPSW files.

The default generator on both Electra and Chimera is 0xbd34a880be0b53f3 for those who would like to save blobs or use existing saved blobs.

Chimera uses Substitute, the opensource code modification platform. Substitute is the Substrate alternative offering lower stability and fewer features for developers. From the Sileo package manager, you can install tweaks, hacks, libraries, and apps from repositories. It works fast!

Electra12 Sileo on iOS 12

After each restart of your iPhone, iPad, or iPod device you will need to re-jailbreak iOS using the Chimera app. The Electra12 jailbreak tool automatically detects if your device and iOS version are supported.
