This article will guide you through the process of installing the unc0ver jailbreak on your iPhone or iPad. I'm an expert and I will walk you through the process of downloading unc0ver app, jailbreaking your device, adding repositories, and installing tweaks.
unc0ver jailbreak is undoubtedly the most advanced jailbreak tool released for iOS 11 through iOS 14. I installed the app on multiple devices and I assure you that this is the most stable jailbreak released so far.
Pwn20wnd, the lead developer behind unc0ver, made a lot of effort to make the jailbreak work during the years of development on iOS 11.0 to iOS 14.8. He also delivered 0-day exploits to jailbreak the latest iOS releases.
The jailbreak itself is no longer developed since 29/12/2021. However, the unc0ver app is still a great solution to jailbreak A6-A13 devices running supported iOS firmware. In my opinion, this is the best jailbreak tool.

unc0ver jailbreak is a very popular solution to install Cydia tweaks on iOS 11.0 – iOS 14.8. The jailbreak is packed with a lot of features making the process simple. One of my favorites is its hassle-free detector to determinate the suitable exploit needed for the jailbreaking process. If your device is supported unc0ver will know it.
Pwn20wnd delivered a user-friendly interface for the jailbreak. unc0ver will automatically identify your device's specifics, including its name, model, processor type, iOS version, and kernel version.
Once you've successfully jailbroken your iPhone using unc0ver, several changes will be made to the system 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.
unc0ver jailbreak also installs an SSH server. This feature enables you to connect to your iPhone using a terminal and SSH client. The jailbreak also has the capability to set a nonce generator.
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 fix this issue I use ReProvision to re-sign the app on my iPhone. This allows me to re-jailbreak my device whenever I need to use tweaks or sideloaded apps.
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. It's a great alternative to Substrate developed by Saurik the author of Cydia.
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 jailbreak 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.
On October 26, 2021, iOS 14.8.1 was released to address a critical security vulnerability. This update specifically resolves a significant issue wherein an application could potentially execute arbitrary code with kernel privileges, posing a potential security threat.
While such vulnerabilities are often exploited in the context of jailbreaking, it's noteworthy that the unc0ver jailbreak tool has not been updated to jailbreak iOS 14.8.1.
Additionally, it is crucial to highlight that any subsequent iOS releases, such as iOS 15, iOS 16, and iOS 17, remain unsupported by the unc0ver jailbreak as well. Users are strongly advised to stay away from websites claiming to distribute unc0ver for iOS 17 or unc0ver black.
unc0ver jailbreak does not support iOS 15 and newer, as it has not received any updates to support the latest version of the iOS operating system. Although there are some exploits available for jailbreak.
Moreover, the developer of the unc0ver seems to have abandoned the project, as there have been no recent updates from him since 2021. Let's set it streight. There is no unc0ver jailbreak for iOS 15 – iOS 17. All websites pretending to have this tool are fake.
To jailbreak iOS 15 and beyond there are different solutions available. Our selection of free jailbreak tools has been tested on various iPhones and iPads and has proven to be secure and safe to use.
unc0ver jailbreak was released as an IPA package for sideloading (via PC or on-device tools). To jailbreak your iOS 11 – iOS 14 device you must install it on your iPhone or iPad with your favourite IPA installer. There are no direct install links available. The most recent version of unc0ver IPA 8.0.2 was released on Dec 31, 2021.
unc0ver Jailbreak for iOS 11.0 - iOS 12.4 was initially released as an open-source project, with all files listed on the Undecimus GitHub Repository. If you are using a macOS, building the project is a straightforward process.
The unc0ver source code was first released on July 12, 2019. Pwn20wnd did not update the source code (unc0ver 5.2.0) to the latest releases of the jailbreak 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 Pwn20wnd will ever push a public update for his jailbreak. Still, it is a great learning opportunity for hackers and developers.
There are multiple methods to install unc0ver jailbreak app on your iPhone or iPad. I will walk you throught all of them, but I highly recommend sideloading the IPA with an IPA installer like Sideloadly.
Using this method you can install the unc0ver jailbreak for free on your iDevice. The only requirement is to have an active Apple account and access to a PC or Mac. Let's learn how to install unc0ver.
If you possess a PC or macOS, the most user-friendly method for installing the unc0ver IPA on your iDevices is through sideloading using the Sideloadly app. This software stands out for its straightforward functionality, allowing you to seamlessly sideload the files. It operates by utilizing a free developer-based certificate.
If you lack access to a PC or Mac, an alternative option is to utilize an IPA installer such as BLFGTool to sideload the unc0ver jailbreak onto your iDevice. This installer not only facilitates the sideloading process but also ensures continuous signing, keeping the jailbreak application valid at all times on your iOS 12 – iOS 14 iPhone or iPad.
unc0ver IPA can also be sideloaded onto your device through TrollStore, compatible with iOS 14 to iOS 14.8. Although this method is exclusive to iOS 14, its standout feature is the permanent installation of the jailbreak. Repeat the steps to install u0Launcher on iOS 14.6 – iOS 14.8 to open the jailbreak app.
After successfully installing unc0ver app and jailbreaking your device, consider adding ReProvision Reborn to your toolkit. This straightforward on-device application automates the process of re-signing the unc0ver app every 7 days. It ensures continued functionality and prevents potential revocation issues.
Step 1. Install ReProvision Reborn on your jailbroken device.
Step 2. Download unc0ver IPA and send the file to ReProvision Reborn.
Step 3. ReProvision Reborn will automatically open the IPA file.
Step 4. Tap on the Install button to sign and install.
Step 5. unc0ver app will be available from the Home Screen.
Info: ReProvision Reborn facilitates the signing of IPA files through a free Apple developer certificate, enabling the activation of up to 3 apps with a 7-day revoke-free certificate.
Linus Henze discovered a new bug in CoreTrust that allows any root certificate to permanently sign IPA files for jailbroken iOS 14 and iOS 15 devices. Using his method, you can install the unc0ver app on your device and ensure it remains functional even after rebooting to stock iOS.
unc0ver app version 6.2 supports jailbreaking iOS 11 to iOS 14.3 and can be permanently signed using the IPA Permasigner script available for macOS and Linux.
Follow a few simple steps to permanently sign the unc0ver IPA:
unc0ver Fugu14-based untether
The unc0ver Fugu14-based untethered jailbreak is now available for all arm64e devices (iPhone XS and newer) running iOS 14.3 up to iOS 14.5.1. This means the unc0ver app won't be revoked after 7 days and will continue to function even after your device reboots.
With this untethered jailbreak, you can jailbreak your device anytime without concerns of losing access to tweaks or jailbreak apps. Installing unc0ver Fugu14 is straightforward using the AltStore signing tool along with the latest unc0ver IPA.
To summarize, Fugu14 sets up a placeholder in the Spotlight app and executes additional exploit commands to install unc0ver similarly to any other app from the App Store. The most convenient way to install Fugu14, Cydia, and unc0ver is through AltStore. This method ensures unc0ver remains valid beyond 7 days and survives device reboots by permanently signing the app with AltStore.
When you jailbreak your device, it's essential to add some third-party repositories to Cydia. Since unc0ver supports a rootful environment, not all repositories are compatible with this jailbreak.
During my time using unc0ver as my main jailbreak, I have tested hundreds of repositories offering various tweaks and packages. Below, you can find my top repositories for the unc0ver jailbreak to get you started.
However, if you need even more sources for tweaks you can read my article covering over 80 Cydia Repos and Sources for classic rootful jailbreaks. This will help you to find all the tweaks for iOS you can imagine.
10 best repositories compatible with Substitute:
There are thousands of packages available, so finding the best jailbreak tweaks can be challenging. To save you time, I've created a guide to some amazing tweaks compatible with unc0ver to get you started.
Cydia tweaks can modify the functionality and appearance of apps, the Lock Screen, Home Screen, Dock, Settings app, and almost every other element of the system.
To make it simple, below are my favorite 10 Cydia tweaks for iOS. However, I have reviewed many more tweaks, which you can find in the Cydia Tweaks category on the website. Follow the link to read more.
10 best jailbreak tweaks compatible with unc0ver:
Follow the steps to jailbreak iOS using the latest version of unc0ver app:
| SoC | Device |
| A6 | iPhone 5, iPhone 5C |
| A7 | iPhone 5S, iPad Air, iPad Mini 2, iPad Mini 3 |
| A8 | iPhone 6, iPhone 6 Plus, iPad Mini 4 |

| A11 | iPhone 8, iPhone 8 Plus, and iPhone X |
| A12 | iPhone XS, iPhone XS Max, iPhone XR |
| A13 | iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max |
unc0ver jailbreak will not work with iPhone 15, iPhone 15 Pro, iPhone 14, iPhone 13 Mini, iPhone 13, iPhone 13 Pro, iPhone 13 Pro Max, iPhone 12, iPhone 12 Pro, iPhone 12 Mini, iPhone 12 Pro Max iPhone 11 Pro, iPhone 11, iPhone 11 Pro Max, iPhone XR, iPhone XS Max, and iPhone XS. For newer devices use the Dopamine Jailbreak.
To completely remove the jailbreak installed with unc0ver app enable the Restore RootFS option from Settings. Re-jailbreak the device to restore the backup before the 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.
unc0ver jailbreak creates an APFS snapshot allowing to restoration 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.
unc0ver has been consistently maintained over several years, supporting iOS 11 to iOS 14, resulting in numerous alternatives. Typically, jailbreaks are specific to particular iOS releases. However, unc0ver broke this trend by offering a single solution across multiple firmware versions. It uses different exploits to jailbreak iOS.
Some jailbreak alternatives to unc0ver offer similar features but use different tweak injection libraries and alternative package managers. Others are based on the checkm8 exploit, supporting devices running iOS 11 – iOS 16. Here are my recommended jailbreak alternatives to unc0ver. I've tested all of them myself.
There are more options for jailbreaking your device running iOS 11 – iOS 14. Other alternatives are available, like checkra1n, which is one of my favorites. However, these two jailbreaks have their differences.
unc0ver jailbreak is available as an IPA package that you can install directly on your device. You can sideload this file onto any iOS device using a PC. Additionally, several third-party App Stores offer the option to install unc0ver without a computer through a Safari link. This option may not be available due to revokes.
On the other hand, checkra1n uses the checkm8 vulnerability to jailbreak A5–A11 iPhones and some iPads. The iPhone XS and later models have a patch that addresses this vulnerability making it impossible to proceed with this jailbreak. To use checkra1n, you need both a physical iDevice and a PC.
Since the jailbreak process happens outside of the Home Screen, checkra1n can jailbreak the device without needing an Apple ID, password, or passcode. This technique is also used for iCloud bypass tools for iPhone X and older models to activate the device. Please note that jailbreaking is not equal to unlocking.
unc0ver requires access to the device, including the passcode, to reach the Home Screen. In contrast, checkra1n can jailbreak the device without this requirement, enabling iCloud bypass tools to operate.
In summary, as of 2024, unc0ver remains a reliable solution for jailbreaking iPhones and iPads running iOS 11 through iOS 14. Various installation methods are available, some ensuring the jailbreak app runs permanently without revokes. If unc0ver isn't working for you, try alternative jailbreaks.
It's important to note that unc0ver has not been updated to support iOS 14.8.1, and there is no version compatible with iOS 15 through iOS 17. Exercise caution and download unc0ver exclusively from trusted sources to avoid malware. I highly recommend using unc0ver on supported devices!
