unc0ver jailbreak updated for iOS 12.0-12.4 [DOWNLOAD]

Developer Pwn20wnd has just updated unc0ver jailbreak with support for iOS 12 firmware. Here’s how to jailbreak iOS 12.0-12.1.2 using unc0ver jailbreak.

unc0ver jailbreak with Cydia is now iOS 12-ready

As you might already know, rootlessJB and other similar developer-centric tools lack Cydia support.

But thanks to Pwn20wnd’s relentless efforts, unc0ver is now ready for iOS 12 and that, too, with full Cydia and Substrate support.  

Though Pwn20wnd has tried to incorporate all mainstay jailbreak features, compatibility still seems to be an issue.

This jailbreak, just like the rootlessJB, lacks proper support for A7-A8 as well as the newer A12 devices.

As of this writing, only devices with A8X-A11 chips are supported. If you happen to own a supported model that’s present in the list below, you can follow the tutorial given below.

Requirements

  • A compatible iPhone or iPad running iOS 12.0-12.1.2
  • A computer running Windows, macOS, or Linux (optional)
  • Cydia Impactor (optional)
  • Internet connection

Preparing your device for jailbreak 

Before you jailbreak, keep the following things in mind:

  • Remove any existing OTA firmware file by navigating to Settings > General > iPhone Storage and reboot your device. Running the jailbreak app without deleting and removing the OTA profile may result in a bootloop.

  • If you don’t have an OTA profile installed, you can skip the step above.
  • Some repositories may not work with Cydia due to a bug in Apple’s code on iOS 12. 
  • Cydia and Substrate are fully compatible with all supported iOS 12 devices listed above. You will able to install all iOS 12-compatible Cydia tweaks after jailbreaking.
  • If you are a rootlessJB user, just follow the tutorial given below and it will get automatically uninstalled.
  • Download the IPA file beforehand and place it on your desktop if you wish to go the computer route.

How to jailbreak iOS 12.0-12.1.2 with unc0ver

With Computer 

Step 1 First and foremost, connect your Apple device to your computer.

Step 2 Launch Cydia Impactor and wait for it to recognize your device. You can get Cydia Impactor from this link if you don’t have it installed on your PC or Mac already. 

Step 3 Drag the IPA file you downloaded from the link above to Cydia Impactor’s window.       

Step 4 Enter your Apple ID e-mail login and password.

Step 5 Wait for the installation to finish.

Step 6 Launch unc0ver from your home screen and tap the Jailbreak button. At this stage, you can safely disconnect your device from your computer.

Step 7 The app will now display the following message – “The system snapshot has been successfully renamed. The device will now be restarted”. Press OK to restart your device.

Step 8 After restarting, start the jailbreak app again and tap Jailbreak.

Step 9 When the app completes 27/38 steps, press OK to reboot the device. It’s perfectly normal for the app to take two restarts before it installs Cydia on your device.

Step 10 Relaunch the app again after your device reboots and tap Jailbreak again. Your iPhone/iPad will now respring.

Step 11 Launch Cydia from your home screen and start installing your favorite tweaks.

Step 12 (Optional) Remove rootlessJB, iSuperSU, and Filza as you no longer need them.

Without Computer

Step 1 Open jailbreaks.fun on Safari web browser. Alternatively, you can use Ignition or any other reputed installer such as Panda Helper.

Step 2 Go to the Apps tab and select Unc0ver -new Beta.

Step 3 Tap GET.

Step 4 Select Install when the installation popup is displayed. Go to your home screen to check progress. 

Step 5 Once the app appears on the home screen, open it. Tap Jailbreak.

Step 6 Once the exploitation process (2/38) is complete, the app will display a popup notice – “The system snapshot has been successfully renamed. The device will now be restarted”. Press OK to restart your device.

Step 7 After rebooting your iPhone/iPad, launch the unc0ver app again and tap Jailbreak again.

Step 8 Wait for the app to complete 27 steps in the exploitation stage and display the following notice – “Bootstrap has been successfully extracted. The device will now be restarted.”. Press OK.

Step 9 Relaunch the app again after your device reboots and tap Jailbreak again. Wait for your device to respring.

Step 10 Start Cydia from the home screen.

Step 11 (Optional) Enable wiggle mode and remove rootlessJB and all its associated applications from your device.

That’s all there’s to it. The tutorial is fairly straightforward and easy to follow. However, if you run into issues, just leave a comment below.
