In case you missed it, the CoolStar-led Electra Team has made good on its promise to release an iOS 12.0-12.1.2 jailbreak with full support for A12(X) devices, but unexpectedly changed the name of the project from Electra12 to Chimera just in time for the release.

In this tutorial, we’ll show you how to jailbreak your iOS 12.0-12.1.2 device with the new Chimera jailbreak tool.

Chimera can jailbreak all iOS 12.0-12.1.2 devices, and so a supported device list isn’t necessary. If your handset is running one of these firmware versions, then you’re good to go.

Step 4 Tap on the Chimera app on your device’s Home screen:

Step 5 Next, tap on the round Jailbreak button in the Chimera app:
