What is unc0ver?

unc0ver Jailbreak is a free application for iOS allowing you to exploit the system and install Cydia on your iPhone or iPad. It automatically detects device name, model, processor type, iOS Version & Kernel Version, to select the right exploit to jailbreak your device.

After jailbreaking an iPhone unc0ver block by default iOS auto-updates, installs Cydia and OpenSSH, and disables app revokes. You can access the best repositories with tweaks with the Cydia package manager. There is more option available but we will get to them later.

By default, the jailbreak installs also an SSH server that allows you to connect to your device using a terminal and SSH client. This jailbreak can set nonce generator as well. Because this is a semi-untethered jailbreak after every restart of your iPhone or iPad the jailbreak will be removed.

unc0ver jailbreak uses Substitute, a tweak injection system that runs on already jailbroken devices. Substitute 2.0 provides unprecedented app loading speeds for unc0ver and checkra1n jailbreaks on iOS 11 - iOS 14 using a newly designed tweak injection system that allows loading a big number of tweaks for ultimate customization with minimal overhead.

Note: unc0ver app isn't under active maintenance and it doesn't look like it will be ever updated to support iOS 15 jailbreak or iOS 16 jailbreak.

unc0ver is packed with a lot of useful settings. One of the options "Restore RootFT" allows to effectively uninstall the jailbreak without losing any user data. If Cydia will stop working correctly you can use "Reinstall Cydia" to reinstall the cydiainstaller package. This will fix the issue.

From the Settings page, you can also activate the options to enable dark mode, load tweaks, refresh icon cache, export TFP0, and re-install OpenSSH server. On top of that, you can also enable to show the log window to view what's going on in the background when jailbreaking.

unc0ver was never updated to support iOS 15. There are exploits available to access read and write privileges but for the moment there is no jailbreak with support for any iOS 15 version. It seems like the developer abounded the project because he is not active for months.

The list of supported devices and firmware by unc0ver is a bit complicated and it depends on those variables. Once installed, unc0ver will automatically detect if your device is supported.

unc0ver Jailbreak for iOS 11.0 - iOS 12.4 was released as an open-source project with all files listed via GitHub Repository. You can build the project with simple steps on macOS. The source code was released on 12 Jul 2019 and it was not updated to the latest releases of unc0ver.

As long as you have standard libraries for Xcode projects you are good to go. 55% of the code is written in C and 42% in Objective-C. Source Code is under BSD 3-Clause License. It doesn't look like the source code will be ever released to the public for newer iOS releases.

How to install unc0ver on iOS

To download unc0ver and install the app on your iPhone it's required to use a computer to sign and install the IPA file to your iPhone and iPad. @Pwn20wnd recommends installing the jailbreak tool with AltStore, but it's much easier using Sideloadly.

We provide also direct web links to a signed unc0ver Jailbreak IPA that can be installed directly on your iPhone without using a computer. Those files are signed with a globally available certificate that gets revoked by Apple. It means that the app will install or open on your iDevice.

unc0ver untether

Linus Henze, the dev behind Fugu14 Jailbreak and the untether for iOS 14.3 up to iOS 14.5.1, discovered a new bug where CoreTrust allows to use of any root certificate to permanently sign any IPA file for all jailbroken devices running iOS 14 and iOS 15. Using this method you can install the unc0ver app on your iDevice so it will continue to work when rebooted to stock.

unc0ver app 6.2 with support for jailbreaking iOS 11 up to iOS 14.3 can be permanently signed with the recently released IPA Permasigner script for macOS and Linux.

Permanently signing the unc0ver IPA with Permasigner on macOs via terminal app.

With a few simple steps, it will permanently sign the unc0ver.IPA to allow the app to run without revokes and also on stock iOS. Below you can find the permanently signed unc0ver app.

  1. Download unc0ver-6.2-Untether.deb
  2. Install unc0ver app for iOS 14.0 - iOS 14.3 with a preferred method.
  3. Jailbreak the iOS 14 system with the installed app.
  4. Install the unc0ver Untether DEB package with Filza.
  5. Restart the device and re-jailbreak with unc0ver app.

Recent releases of the unc0ver app can be signed permanently but they will fail to jailbreak due to the error that occurred while disabling codesigning on step 18. To make the latest unc0ver 8.0.2 app work permanently you must to sign and install the app with AltStore and jailbreak. Next, install the unc0ver untether 8.0.2 deb package on your device.

Basically, the Fugu14 untether sets a placeholder in the Spotlight app and executes a few more exploit commands to install unc0ver like any other app from the App Store.

The easiest way to install Fugu14 on your device with Cydia and unc0ver is through AltStore. Using this method unc0ver will not expire after 7-days or after a reboot of your device. AltStore will not allow for an untethered jailbreak instead it will permanently sign the unc0ver app.

  2. Tap on the "Jailbreak" button to start.
  3. Wait till the system is exploited and respring your device.

Whenever you reboot the jailbreak will be disabled. Open the app again and tap on "Jailbreak". If the app will expire, install it again with the preferred method.

Remove unc0ver jailbreak

To completely remove jailbreak installed with unc0ver App enable the Restore RootFS option from Settings. Re-jailbreak the device to restore the backup before jailbroken state.

If there is no option to re-jailbreak restart the device first. There is no need to manually remove installed tweaks and apps when using this function.

  1. Open the unc0ver app and go to Settings.
  2. Toggle the Restore RootFS (rec0ver) and Refresh Icon Cache options.
  3. Press Jailbreak or Re-jailbreak on the main screen.

unc0ver jailbreak creates an APFS snapshot allowing to restore of the iOS system to the state before jailbreak. If the Restore RootFS feature will not work there is another solution. SnapBack app can easily access the "orig-fs" snapshots and restore the system with one tap.

Sign unc0ver IPA on the device

After installation, the app can be revoked and will stop working or opening. Therefore it is a good practice to use a jailbreak tool like ReProvision to sign unc0ver Jailbreak directly on an iOS 14 iDevice. Reborn will do it automatically so you will never forget to do it.

  1. Navigate to the top of this page.
  2. Tap on Install via ReProvision and tap Open.
  3. ReProvision will download unc0ver IPA automatically.
  4. Tap on the Install button to sign and install.

Links provided by popular 3rd party app stores can install the jailbreak app without a PC or Mac. The problem with using this method is that the IPA file is signed with a globally available certificate mostly used to pirate apps and games available in the official App Store.

Therefore Apple is revoking those certificates and apps will not install. As result, the unc0ver app will stop working on your device. But when the web links are working, re-sign the unc0ver app with ReProvision Reborn or use one of the available unc0ver permanent sign options.
