That’s right, after months of waiting for an iOS 12 – 12.1.2 utility, it’s now possible to the latest jailbreak A12 devices. In addition to being able to download Chimera for iOS 12.1.2 and lower, this tutorial will guide you through the steps to jailbreak iOS 12 – 12.1.2 successfully.

Chimera A12 Jailbreak Tutorial:

Step 1: Download the latest version of the Chimera IPA (app), the most recent version of iTunes, and Cydia Impactor for either Windows or Mac. All downloads can be found in the download section listed below (jump there by clicking here).

Note: You may also need to grab the tvOS beta profile too if you encounter issues with frequent iOS update notifications – more on that later.

Step 2: Connect your iPhone or iPad to your computer via a standard USB cable and ensure iTunes recognizes your iDevice. If iTunes doesn’t, you’ll need to establish a connection by tapping “Trust” on your iDevice and “Continue” inside iTunes.

Step 3: Quit iTunes and launch Cydia Impactor (again this is available to download below).

Note for macOS: mount the .dmg Cydia Impactor download and drag the program to your applications folder. If you receive an alert about not being able to open Cydia Impactor because it was downloaded from the internet, you may need to allow it inside the System Preferences app > Security & Privacy.

Note for Windows: the download will come in a .zip format – you’ll need to extract Cydia impactor from the zipped file. We recommend extracting the program to your desktop as it’s easy to access. Do not run the program as an administrator, as that disables the ability to drag files into the interface, which is key for the iOS 12 unc0ver jailbreak. Merely run Cydia Impactor as you would a normal application.

Step 4: Verify that your iOS 12 A12 Device is recognized by Cydia Impactor and that it’s selected in the top drop-down menu. Drag the Chimera .ipa into the Cydia Impactor interface.

Step 5: Input your Apple ID, followed by your password and click “OK”. This step simply uses Apple’s own self-signing service. Your information is neither collected by Saurik (the creator Cydia) nor is it directed through any server other than Apple’s.

Important Note: if your Appel ID has two-step verification, you’ll be required to create a single app password. However for the sake of simplicity, we recommend that you just create a new Apple I’d instead  (click here). This is also useful if you don’t want to use your personal Apple ID for any reason.

Step 6: Once the Chimera A12 Jailbreak iOS 12.1.2 app is installed, open the Settings app. Navigate to General > Device Management. From there find your Apple ID certificate (it was used to sign the jailbreak app in the previous step), tap it, and tap “Trust” two times.

Step 7: You will need to delete any pending OTA software updates your device may have attempted to auto install. Navigate to Settings > General > iPhone Storage (which will dynamically say iPad or iPod depending on device), find the software update, tap it, followed by “Delete Update”. Next, install the tvOS beta profile to prevent OTA iOS software updates from loading – this is available in the download section.

Step 8: Open the Chimera app on your iDevice and tap the jailbreak button. Your iDevice will the reboot.

Step 9: When your iDevice comes back, open the Chimera app again and tap jailbreak once more. At this point, the A12 jailbreak iOS 12.1.2 process is now complete.

Important Notes after Chimera Jailbreak

Once you’re jailbroken, it’s important to realize that because this utility is semi untethered, you will be required to re-run the unc0ver app every time your device powers off and turns back on.

Furthermore, unless you’re a registered developer (i.e. you pay Apple $99/year to develop and publish apps on the App Store), you’ll be required to re-run the steps listed in this tutorial to install the Unc0ver jailbreak every seven days. This restriction is due to the aforementioned limitations of self-signing applications through Apple.
