Exploring the Benefits of an Untethered Jailbreak

Share This:

Mobile devices have become an integral part of our lives, offering a multitude of features and functionalities. However, these devices often come with certain limitations imposed by the manufacturers. Jailbreaking is a process that allows users to gain access to the root file system of their devices, enabling them to bypass these restrictions and customize their user experience. One important distinction within the realm of jailbreaking is the difference between tethered and untethered jailbreaks. In this article, we will delve into the concept of untethered jailbreaking, its advantages, and its implications.

What is Untethered Jailbreak?

Untethered jailbreaking refers to a method of gaining root access to a device’s operating system that does not require the device to be connected to a computer every time it restarts. Unlike tethered jailbreaks, which require the device to be reconnected to a computer to maintain the jailbroken state, untethered jailbreaks offer a more convenient and seamless experience. Once an untethered jailbreak is successfully performed on a device, the user can freely restart their device without the need for a computer intervention.

Advantages of Untethered Jailbreaks:

1. Freedom to Customize: One of the most significant advantages of untethered jailbreaking is the ability to customize your device to a greater extent. Users can install custom themes, modify system files, and access a plethora of third-party applications that are not available through official app stores. This opens up a world of possibilities for users who want to personalize their device and enhance its functionality.

2. Access to Additional Features: Untethered jailbreaks often provide access to features and functionalities that are not available on stock devices. This includes the ability to customize the control center, enable system-wide dark mode, and install extensions that enhance the device’s capabilities. These additional features can greatly enhance the user experience and make the device more versatile.

3. Sideloading Apps: Another advantage of untethered jailbreaks is the ability to sideload applications that are not available through official app stores. This allows users to install apps from alternative sources, giving them access to a wider range of apps and utilities. Sideloading can be particularly useful for developers who want to test their apps on real devices without going through the official app review process.

Implications and Considerations:

While untethered jailbreaking offers numerous benefits, it is important to consider the potential drawbacks and implications before proceeding with the process. Here are a few points to keep in mind:

1. Security Risks: Jailbreaking a device inherently introduces security risks. By bypassing the device’s security measures, users expose themselves to potential malware and unauthorized access. It is crucial to exercise caution, only install trusted tweaks and applications, and keep the device updated with the latest security patches.

2. Voiding Warranty: Jailbreaking a device typically voids the manufacturer’s warranty. This means that if any hardware or software issues arise, the manufacturer may refuse to provide support or service. Users should weigh the benefits of jailbreaking against the potential loss of warranty coverage before proceeding.

3. Stability and Performance: Jailbreaking can sometimes lead to stability issues or performance degradation. Installing incompatible tweaks or modifications may cause the device to crash or slow down. Users should research and choose reputable tweaks, and regularly monitor the device’s performance to ensure a smooth experience.

Untethered jailbreaking offers users the freedom to customize and enhance their devices beyond the limitations imposed by manufacturers. It provides access to a plethora of features and applications that are not available through official channels. However, it is important to consider the potential security risks, warranty implications, and stability concerns before deciding to jailbreak a device. Ultimately, the decision to jailbreak should be made after careful consideration of the individual’s needs and priorities.

What is the Difference Between Tethered and Untethered Jailbreak?

Tethered jailbreaking and untethered jailbreaking are two different methods used to modify and gain access to the operating system of a device, such as a smartphone or tablet, in order to remove certain restrictions imposed by the manufacturer. The main difference between the two lies in the level of convenience and flexibility they offer to the user.

1. Tethered Jailbreak:
– Tethered jailbreaking requires the user to connect their device to a computer every time it is restarted.
– This means that if the device is turned off or the battery dies, the user needs to reconnect it to a computer in order to boot it up and access the jailbroken features.
– Tethered jailbreaking can be seen as a temporary solution, as the device reverts back to its original state if it is not connected to a computer during startup.
– This dependency on a computer can be inconvenient for users who need to restart their device frequently or who do not have immediate access to a computer at all times.

2. Untethered Jailbreak:
– Untethered jailbreaking, on the other hand, does not require the user to reconnect their device to a computer after every restart.
– Once the device has been successfully untethered jailbroken, it remains in that state even if it is turned off or the battery dies.
– Users can freely restart their device without the need for a computer, as the jailbroken features and modifications persist.
– Untethered jailbreaking offers greater convenience and flexibility to users, as they can use their device without any limitations or the need for external support.
– It is considered a one-time activity that does not require repeated connection to a computer.

Tethered jailbreaking requires users to reconnect their device to a computer every time it is restarted, while untethered jailbreaking is a one-time activity that allows users to freely restart their device without any restrictions.

Is There An Untethered Jailbreak For iOS 14?

There is an untethered jailbreak available for iOS 14 called Fugu14. This jailbreak provides users with the ability to modify their iOS devices and install unauthorized apps and tweaks. It includes several vulnerabilities, identified by their respective CVE numbers: CVE-2021-30740, CVE-2021-30768, CVE-2021-30769, CVE-2021-30770, and CVE-2021-30773.

Here are some key details about Fugu14:

1. Untethered Jailbreak: Fugu14 is an untethered jailbreak, which means that once it is installed on an iOS 14 device, the jailbreak remains active even after rebooting the device. This provides users with persistent access to the jailbreak features.

2. Kernel Exploit: Fugu14 utilizes a kernel exploit to gain elevated privileges and bypass the security measures imposed by the iOS operating system. This exploit allows users to access and modify system files and settings that are typically restricted.

3. Kernel PAC Bypass: In addition to the kernel exploit, Fugu14 includes a kernel PAC (Pointer Authentication Codes) bypass. This bypass allows the jailbreak to circumvent the pointer authentication protections implemented by Apple, further enhancing its capabilities.

4. PPL Bypass: Fugu14 also incorporates a PPL (Platform Policy Layer) bypass, which allows the jailbreak to bypass the restrictions imposed by the PPL framework. This bypass enables the installation and execution of unauthorized apps and tweaks on the iOS device.

It’s important to note that jailbreaking an iOS device can have both positive and negative implications. On the positive side, it grants users more control and customization options for their devices. However, it also exposes the device to potential security risks and may void the device’s warranty.

Fugu14 provides an untethered jailbreak solution for iOS 14, allowing users to customize and modify their devices beyond the limitations imposed by Apple.

Is Checkra1n Untethered?

Checkra1n is not an untethered jailbreak. It is a semi-tethered jailbreak, which means that you will need to connect your device to a computer and run the checkra1n software each time you reboot your device. This is because the jailbreak exploit used by checkra1n, called ‘checkm8’, takes advantage of a vulnerability in the device’s bootrom, which is a read-only memory that is not updated or patched by software updates.

The checkm8 exploit allows the jailbreak to persist even after a reboot, but it still requires the checkra1n software to be run on the device each time it is powered on. This is why it is considered semi-tethered. However, once the checkra1n software is run, the device will be jailbroken and you will have access to all the features and customizations that come with it.

Please note that jailbreaking a device may void its warranty and can introduce security risks. It is important to proceed with caution and only jailbreak your device if you understand the potential implications.


An untethered jailbreak provides users with the ultimate freedom and convenience when it comes to customizing and modifying their iOS devices. Unlike tethered jailbreaks, which require users to reconnect their device to a computer every time it is restarted, untethered jailbreaks offer a one-time activity that eliminates this restriction.

With an untethered jailbreak, users are able to enjoy the benefits of a jailbroken device without the hassle of having to constantly reconnect to a computer. This means that they can restart their device whenever they want without worrying about losing their jailbreak or having to go through the jailbreaking process again.

Additionally, untethered jailbreaks provide users with more flexibility in terms of customization and modification options. They can install a wide range of third-party apps, tweaks, themes, and utilities that are not available on the official App Store. This allows users to personalize their device, enhance its functionality, and access features that are otherwise restricted by Apple.

Furthermore, untethered jailbreaks often come bundled with additional exploits and bypasses, such as kernel exploits, PAC bypasses, and PPL bypasses. These vulnerabilities provide users with even more capabilities to bypass security restrictions and gain deeper access to the device’s operating system.

An untethered jailbreak offers users the best of both worlds – the freedom to customize and modify their iOS device, along with the convenience of a persistent jailbreak that doesn’t require constant reconnection to a computer. It opens up a whole new world of possibilities and allows users to truly make their device their own.
