What is unc0ver?

unc0ver jailbreak is an app that allows you to exploit iOS 14 and install Cydia on your iPhone or iPad. This user-friendly app automatically detects your device's name, model, processor type, iOS version, and kernel version to determine the appropriate exploit to jailbreak.

Once you've successfully jailbroken your iPhone using unc0ver, several changes will be made by default. For instance, iOS auto-updates will be blocked, Cydia and OpenSSH will be installed, and app revokes will be disabled. With the Cydia package manager, you can easily access the best repositories with various tweaks. Additionally, there are other options available.

In addition to Cydia, unc0ver jailbreak also installs an SSH server by default. This feature enables you to connect to your iDevice using a terminal and SSH client. The jailbreak also has the capability to set a nonce generator. However, it is important to note that since this is a semi-untethered jailbreak, you will need to reapply the jailbreak every time you restart your iPhone.

To enable you to take full advantage of your already jailbroken devices, unc0ver jailbreak uses Substitute, a powerful tweak injection system. With the newly designed tweak injection system in Substitute 2.0, unc0ver and checkra1n jailbreaks on iOS 11 through iOS 14 are now able to achieve unprecedented app loading speeds. This system permits the loading of a large number of tweaks, allowing for maximum customization with minimal overhead.

Note: Unfortunately, unc0ver jailbreak is no longer under active maintenance, and it appears unlikely that it will receive updates to support future iOS 15 or iOS 16.

unc0ver comes loaded with a plethora of useful settings. For instance, the "Restore RootFS" option allows you to effectively uninstall the jailbreak without losing any user data. In case Cydia stops working correctly, you can use the "Reinstall Cydia" option, thereby resolving the issue.

The app provides a variety of additional options, including dark mode, tweak loading, icon cache refreshing, TFP0 exporting, and OpenSSH server reinstallation. Moreover, you can enable the log window to observe the processes taking place in the background while jailbreaking.

Determining which devices and firmware are supported by unc0ver can be a bit complicated, as it depends on a variety of variables. However, once installed, unc0ver jailbreak will automatically detect whether your device is supported or not. It supports all releases of iOS 14 – iOS 14.8.

Currently, unc0ver jailbreak does not support iOS 15, as it has not received any updates to support the latest version of the iOS operating system. Although there are some exploits available to access read and write privileges, at present, there is no jailbreak that supports any iOS 15 version. Moreover, the developer of the unc0ver project seems to have abandoned the project, as there have been no recent updates from them for several months.

unc0ver Jailbreak for iOS 11.0 - iOS 12.4 was initially released as an open-source project, with all files listed on the GitHub Repository. If you are using a macOS, building the project is a straightforward process. The source code was first released on July 12, 2019, and has not been updated to the latest releases of unc0ver with support for iOS 13 or iOS 14.

As long as you have the standard libraries for Xcode projects, you should be able to proceed without any issues. Approximately 55% of the code is written in C, and 42% in Objective-C. The source code is under the BSD 3-Clause License. However, it seems unlikely that the source code will ever be released to the public for newer iOS releases.
