Download unc0ver jailbreak for iOS 14.0-14.3

unc0ver jailbreak has been released for iOS 14.0-14.3 with support for all compatible devices. Here’s how you can jailbreak iPhone 12, iPhone 11, and older devices running iOS 14.

What is unc0ver?

unc0ver is a semi-untethered jailbreak for iOS 14.0-14.3 operating systems. It is developed by veteran jailbreak developer Pwn20wnd, who has been maintaining the project since 2018.

The latest iteration of this jailbreak tool uses a custom exploit based on the CVE-2021-1782 kernel vulnerability, which was recently disclosed by an anonymous researcher.

Unlike checkra1n, unc0ver does not require a PC to load the exploit. You can install this tool on-device with a signing tool like AltStore.

The latest update (v6.0.0) offers compatibility for all devices including the current flagship from Apple, the iPhone 12. The Pro, Pro Max, and Mini variants are also compatible since they come with the A14 Bionic system-on-chip.

Additionally, the latest update to unc0ver also adds support for iOS 13.5.1-13.7 as well as iOS 12.4.9-12.5.1. 

Before we move on to the tutorial, make sure you own a supported device that runs iOS/iPadOS 14.0-14.3.

Download and run unc0ver    

Step 10 Launch Safari and download the latest IPA file using the link given above.

Step 11 Your device will now ask you to confirm the download. Tap Download to authorize the download. 

Step 12 Wait for the download to finish. The download may take a while to complete as the IPA file is large.

Step 13 Once the download is finished, select the downloaded IPA file from Safari’s built-in download manager. Now select the “open with” icon present in the top-right corner of the screen.

Step 14 Select AltStore and copy the IPA to AltStore to sideload it on-device.

Step 15 Wait for AltStore to sideload the unc0ver jailbreak app. Once the app is sideloaded successfully, go back to your home screen and launch the app.

Step 16 Tap the Jailbreak button to kickstart the exploitation process. This should not take more than 10-15 seconds.

You can also customize its settings to enable advanced options. However, the default options will suffice for most users.

Step 17 The app will now display the “Support unc0ver” screen. Tap the cross button in the top-left corner to go back. If you would like to support the project, you can become a patron or donate to their developer team via PayPal.   

Step 18 Once the jailbreak process is complete, the app will display the following message: 

Jailbreak Completed
The system needs to reboot to finish the jailbreak process. When your device reboots, re-run the jailbreak the complete the process.

Tap OK to continue to the next stage of the process.

If the exploit fails for some reason, simply reopen the jailbreak app and run it again.

Step 19 Your device should now reboot. Now open the unc0ver app again and tap Jailbreak to complete the exploitation process.         

Launch Cydia

Step 20 If all goes well, Cydia and Substitute will appear on your home screen after your device restarts. Launch Cydia and start installing your favorite jailbreak tweaks!

Step 21 (Optional) Open Substitute application from the home screen. The system-wide tweak injection will be enabled by default. If it is disabled, turn on the Enable Tweak Injection option to make sure your tweaks remain functional.         

Substitute manager for iOS

As a word of caution, we advise our readers not to install incompatible Cydia tweaks on their devices.

Installing an incompatible tweak may cause your device to get stuck in a respring loop or boot loop. Also, an incompatible tweak can be a source of instability and may cause battery drain or make the UI glitchy.     

Wait for the developers to release updates for your firmware version before you go about installing tweaks.   

How to re-jailbreak your device once it reboots

Since unc0ver is semi-untethered in nature, you will lose your jailbreak once your device reboots. So, you will want to “re-jailbreak” your device to get into a jailbroken state again.

Just make sure that the app is signed beforehand. If the app expires, you must resign it using AltStore or another signing tool.   

  • Simply open the unc0ver app.    
  • Press the Jailbreak button.
  • Voila! Your device is jailbroken again.
