Download Chimera jailbreak for iOS 12.0-12.2

Electra Development Team just released the A12-compatible Chimera jailbreak for iOS 12.0-12.1.2. Here’s how you can download and install it on your iPhone, iPad, and iPod touch.

What is Chimera?

Chimera is a semi-untethered jailbreak tool for iOS 12.0-12.1.2 firmware. It is developed and designed by Coolstar, Nullpixel, Alessandro Chiarlitti, and AppleBetas.

Written from the ground up, Chimera is the first “true” jailbreak tool developed for iOS 12.

Unlike unc0ver and other primitive alternatives, it offers full compatibility with devices having the A12/A12X processor (iPhone XS/XS Max, XR, and the new iPad models).    

Chimera jailbreak

Chimera is based on Brandon Azad’s voucher_swap exploit for iOS 12 and features a full-blown CoreTrust bypass that ensures the user doesn’t have to resign binaries over and over again. 

Up until now, all major developers have shipped Cydia as the default package manager with their tools.

What sets it apart from other alternatives is the inclusion of Sileo,  a modern Cydia replacement designed for the latest Apple devices, as the default package manager. 

You can grab this tool using the link below. But before you do that, make sure that your device is present in the compatibility list below.

How to jailbreak iPhone XS, XS Max, XR and below with Chimera

With computer

Step 1 Unlock your Apple device and connect it to your computer.

Step 2 Launch Cydia Impactor and ensure it successfully recognizes your device. If you don’t have it installed on your computer, download it from this link

Step 3 Download the latest IPA file from the download section above. 

Step 4 Drag this IPA file over to Cydia Impactor to start the installation.

Step 5 Cydia Impactor will now prompt you to enter your username and password. Enter your credentials and hit enter.

Step 6 Wait for the installation to complete. Once done, the app should appear on your home screen. You can disconnect your device from your computer at this point.  

Step 7 Open the stock Settings app and navigate to General > Profiles & Device Management. Select the developer certificate associated with your email address and tap Trust

Step 8 Open the Chimera application and hit the Jailbreak button to start the jailbreak process. The spinning wheel 

Step 9 Wait for the exploitation to complete. If the app displays “Reboot Required”, the exploit has succeeded and you will now have to restart your device to complete the jailbreak process.

If your iPhone/iPad restarts before it the spinning wheel completes all the three steps, the exploit has failed. Go back to step 8 and keep trying until the exploit succeeds.

Step 10 Launch Sileo Cydia alternative from the home screen and start downloading your favorite tweaks!

Without computer

Step 1 Open Safari and visit to this website – https://ignition.fun

Step 2 Navigate to the apps section, select Jailbreaks > Chimera.

Step 3 Tap GET and wait for the installation to commence. Once your device displays the installation prompt, press Install to confirm. Wait for the installer to load the app on your device.

Step 4 Go to Settings > General > Profiles & Device Management and trust Ignition’s enterprise certificate. If you are unable to locate the required certificate to trust, simply select the one that’s currently untrusted.

Step 5 Close all open apps from the app switcher and go to your home screen. 

Step 6 Open the Chimera app and hit Jailbreak.

Step 7 Wait for the spinning wheel to complete the required steps. At this stage, you would want to reboot your iPhone or iPad as it is a part of the exploitation process. 

Step 8 Once the app displays “Jailbroken”, your device will be successfully put in jailbreak mode.  

If, for some reason, you are unable to get it working, check out the video given below.

How to re-jailbreak your iPhone, iPad, and iPod 

Since Chimera is a semi-untethered tool, your device will eventually run out of jailbreak juice. The reason being that Apple allows free developer certificates to only sign an app for a period of seven days.

You will no longer be able to use the jailbreak application should you not resign it at regular intervals.

Below is a quick tutorial that outlines how to re-jailbreak your Apple device if you reboot it into the no-jailbreak mode and are unable to use the app.

Step 1 Delete the existing Chimera application from your iPhone XS/XS Max/XR or below.

Step 2 Open Cydia Impactor again and drag the latest IPA file over to it.

Step 3 Enter your credentials and wait for the app to get loaded on your device.

Step 4 Run the app and hit the Jailbreak button.

That’s all there’s to it. If you get stuck anywhere or get hung up on unforeseen issues, feel free to leave a comment below.
