When you jailbreak an iOS device, you remove the restrictions set by Apple and its developers. Freeing your iOS device means that you can install applications that are not from Apple’s iTunes App Store and you can modify different settings that are prohibited to regular iOS users. Jailbreaking your iOS device also gives you the ability to unlock your phone and make it compatible with other carriers.

Of course, Apple won’t advise their users to jailbreak their phones and devices. Jailbreaking is possible due to a series of kernel patches. Jailbreaking an Apple device will also allow root access to iOS. This will, in turn, allow you to download and install third-party applications and extensions which are unavailable through the official Apple App Store.

If you want to jailbreak iOS devices, here is an article that can help you out.

Remember this is just at the initial stage for jailbreaking iOS version 12.4. This means that updates will keep coming to make it better and flawless. But you can still use this version as it is considered safe. Before you install any tweaks, make sure that those tweaks are updated to work with iOS 12.4 jailbreak in Chimera and Sileo. Installing old tweaks may cause some issues. This iOS 12 version of the Chimera jailbreak is available for versions 12 to 12.4. It also has a version that is compatible with TvOS 12-12.4 named Chimera TV.

You can use this website for Chimera Jailbreak to download the IPA file. You also have to install it using the Cydia Impactor, as you already know the apps like TweakBox and Ignition are currently down.

This jailbreak supports every device running on iOS 12 up to iOS 12.1.2, iOS 12.4 jailbreak supports only for A7 – A11 devices.


Back-Up Your Device

The most important thing before you attempt to jailbreak your iPhone is to create a backup There are several ways to backup your phone. First, is to use iCloud which will allow you to backup your important files without connecting to a computer. Then, you also have the choice of connecting your iPhone to iTunes. Once your device has been located, iTunes will automatically create a backup. Lastly, if your Macbook runs on the Catalina update, you can use Finder to backup your phone.

Make sure that you run a backup on your device when preparing for the jailbreak process so that all your media files: music, apps, movies, photos, videos, and everything else are stored in a secure location. This will help you to restore and get everything back once you complete the jailbreak.


Removing OTA Updates

Make sure you do not have any downloaded Over The Air (OTA) updates on your device. In case you do, just go to your Settings and click on iPhone Storage. You can locate OTA updates here and delete them to lessen the chance of encountering a problem. Delete these updates before attempting a jailbreak. Also, you can remove the RootlessJB (Jailbreak) if it’s installed on your iPhone to lessen problems.


How To Jailbreak iOS Using Chimera via Computer


Initial Steps

The first thing you need to do is to download the IPA file from the link above and also download the Cydia Impactor from the internet. Because you need to sideload an IPA file with the Cydia Impactor. Download the file that will work on your computer’s OS. You can also sign any IPAs files through Cydia Impactor Alternative, iOS App Signer if Cydia impactor is down.

Once you’ve finished downloading the two software, open Cydia Impactor. Connect your device to it using your lightning or another cable, don’t use any third parties Chinese cable because those usually disconnect fast. Then, trust the application, and drag and drop the IPA file onto this.

A prompt will then ask you to sign in using your Apple ID and once done will start the installation process. Make sure to trust the application before you open it.

Next, open the installed application. The UI looks pretty nice with colors that change itself and that makes the overall look more interesting. On this page, you will see a button below which tells you about your iPhone compatibility. If you’re encountering problems, you can disable the tweaks to make things run smoother. If you have the saved blobs, you can activate the Nonce option.

After pressing the button “Jailbreak”, it may ask you to reboot the device, when the phone is on you need to run the Chimera jailbreak immediately after that. Now, when you hit the “Jailbreak” button after the process runs for a few seconds or a minute, it will ask you to reboot the device to finish the jailbreaking process.


Finishing Steps

Press the “OK” button to reboot, after that, you will need to open the Chimera app to complete the process. This process will take 2 to 3 attempts because it will sometimes crash or require reboots. In some situations, you might see a bug that results in a completely black screen.

Bugs are present but will be fixed on future updates by the Electra team. If you face this problem while installing Chimera Jailbreak, you just need to restart your phone. Open Chimera again, if it says “jailbreak” then you need to repeat the jailbreak process. Otherwise, if it states jailbroken, then it is successfully installed. Instead of Cydia, a Sileo app would then be installed in its place.

If you encounter an Error 404 while installing updates, you can refresh the page by pulling down on the list.

Sileo looks pretty nice and modern, most of the repositories are compatible with Sileo but some of the older versions do not meet Sileo’s criteria. Those might not work with the Sileo so be aware when you add a repository into Sileo.

In this method, it will show you the many fixes for the problem you might encounter while installing the Chimera jailbreak. Keep in mind that it may not be the solution to every problem you encounter. This will work when installing fresh iOS 12.4 jailbreak or updating your jailbreak as well. For example, you can encounter an error that Sileo isn’t starting or is not appearing after you have jailbroken your device.

If you think that reinstalling the Chimera jailbreak will fix it, it will not work. This is because when you installed it previously your file system already contains those files for the jailbreak. Uninstalling the jailbreak doesn’t remove the files from your file system. To fix or remove those files, you will need to restore your file system. Keep in mind that you’ll lose all your installed tweaks, but not your photos and contacts.

  • Press the button at bottom of your screen and then press Restore RootFS.
  • Next, press “Ok” on the popup stating Root Filesystem Restore. After that, Chimera will display a “Restore Filesystem” option. This will remove everything related to the Chimera jailbreak and will fix not everything, but many of the problems the corrupted files are creating will work properly. This is because it creates binary files in the file system,l so the only reinstallation of the application will not work for you. Restore RootFS is necessary, this will not affect your files or data.
  • Simply press “Restore Filesystem”. After the process is done, try to re-jailbreak using Chimera jailbreak.
