Installing Chimera

If you have a newer device with an A12 SoC, such as the iPhone XS, you can only use Chimera on iOS 12.0 - 12.1.2.

If you are already jailbroken with unc0ver, make sure to properly remove it

Chimera is a semi-untethered jailbreak, meaning it requires a app to re-apply the exploit after a reboot. Click the link to learn more.

Chimera is capable of jailbreaking A12 on iOS 12.0 - 12.1.2 and A7 - A11 on iOS 12.0 - 12.5.1.

Due to how semi-untethered jailbreaks work, the app will need to be re-signed once every 7 days.

We will use AltStore to install the Chimera jailbreak application to your iOS device for use in the next step.

Downloads

• Chimera
• The latest version of AltStore
• The latest version of iTunes if on Windows
• The lastest version of iCloud if on Windows

If you are running iOS 12.0 - 12.1.4, you will need to use AltDeploy

Installing the application

1. Download AltStore for your respective operating system
2. Launch AltStore/AltServer
   • On macOS, open the Mail app and open Mail -> Preferencees in the menu bar
   • Click on the General tab, the Manage Plug-ins, check AltPlugin and apply
3. Connect your iOS Device to your Mac or PC via USB
4. Click AltStore/AltServer in the Menu Bar/System Tray
5. Click Install AltStore
   • Follow all onscreen prompts
6. Open Settings and navigate to General -> Device Management and verify AltStore
7. Download Chimera on your iOS Device and open the .ipa in AltStore
   • Make sure your iOS Device and Mac or PC are connected to the same WiFi network

The Chimera application can now be opened from home screen.

Running Chimera

1. Reboot your phone
   • This is not necessary but recommended
2. Open the Chimera application from your home screen immediately afterwards
3. Tap “Jailbreak”
4. Reboot your phone again when prompted
   • This time, it is necessary
5. Once again, open the Chimera application from your home screen immediately after rebooting
6. Tap “Jailbreak” again

If that app or your device crashes/restarts unexpectedly and the jailbreak isn’t installed, simply try rebooting and running the exploit again until it does work.

You should now be jailbroken with Sileo installed on your home screen. You can use Sileo to install tweaks, themes and more.
