What is Chimera Jailbreak?

Chimera is a jailbreak released as an open-source project. It allows to jailbreak iOS 12.1.3 - iOS 12.5.5 on A7 - A11 devices, and iOS 12.0 - iOS 12.1.2 on all devices (including A12 devices like iPhone Xs, iPhone Xr, and the newest iPad). Depending on iOS download the proper version.

This iOS 12 jailbreak features CoreTrust bypass meaning that binaries don't need to be resigned. Chimera comes with Sileo, a modern package manager, to install tweaks, apps, and other hacks from Repositories. Sileo is a fast alternative for Cydia. Chimera 1.6.4 is the latest version.

Nonce setter works only on iOS 12.1.2 - iOS 12.4.1 on A12.

Chimera Jailbreak

Chimera jailbreak detects automatically supported devices and it allows you to switch between different exploits (machswap2, voucher_swap, sockpuppet) to jailbreak the iOS 12 system. It features also an option to disable tweaks. Use this option to fix system issues with re-jailbreak.

Chimera 1.6.4 is the latest jailbreak for iOS 12.0 - iOS 12.5.5, developed by the same team behind Taurine Jailbreak on iOS and iPadOS 14 - iOS 14.3 devices, the Odyssey jailbreak on iOS 13 devices, and Electra for iOS 11 - iOS 11.4.1. This is a stable jailbreak for iOS 12.

Like almost every modern jailbreak, also Chimera app is packed with Restore RootFS. This feature allows restoring your root filesystem to the state before jailbreak if needed. Use this option to completely remove the jailbreak with all installed tweaks and apps.

Chimera jailbreak comes in two versions. One is dedicated to iOS 12.0 - iOS 12.1.4 for all devices including A12 (iPhone XS and newer) and for iOS 12.2 - iOS 12.5 (before iPhone XS, all A7 - A11 devices).

The jailbreak is using libhooker as Injection Library.

After installation, the app will be revoked and will stop working and opening. Therefore it is a good practice to use the ReProvision app to sign and install Chimera Jailbreak directly on an iOS 12 iDevice. Reborn will do it automatically so you will never forget to do it.

Alternatively, install unc0ver jailbreak to install Cydia on iOS 11.0 - iOS 14.8.

Install Chimera Jailbreak with weblinks

Chimera app can be installed on your iPhone or iPad using direct web links. If you don't own a computer you can try to install the jailbreak using this method. Chimera is usually signed with a pirated certificate that will get revoked by Apple and it will not work on your iDevice.
