Promotion image of Shadow article.

How many times did you try to run an app, and it notified you that it will not open on your jailbroken device due to security risk. With Shadow tweak, you can bypass jailbreak detection to run apps on your iPhone running the latest jailbreak on iOS 14 and iOS 15. This is the best jailbreak detection bypass for iOS 15, including rootless jailbreaks.

Add Shadow Repo to your package manager.

What is Shadow?

Shadow tweak is a lightweight jailbreak detection bypass tweak for iOS 11 up to iOS 15 allowing you to run App Store apps that will not run on jailbroken environment. The tweak is simple to use, but it offers also some advanced hooks to disallow apps to detect installed jailbreak. Shadow jailbreak bypass can run on iOS 15 with Dopamine, Palera1n, and XinaA15.

Once installed, Shadow Tweak will add a dedicated preference pane to the Settings app. From this pane, you can easily toggle the jailbreak detection bypass on and off, enable custom hooks, and configure the jailbreak detection bypass on a per-app basis. Additionally, there is an option to reset the settings if needed. Rootless jailbreaks are also automatically detected.

With Shadow jailbreak bypass tweak for iOS 14 – iOS 15, you can fine-tune the jailbreak detection bypass function to your preferences. This feature is not typically necessary, unless a specific hook is causing app crashes. The hooks are divided into three categories: essential, recommended, and extra, making it easier to understand and use.

Essential hooks are monitoring the file system, loaded modules, URL handlers, and environment variables. Those are most likely used by third party apps to detect if you are running a jailbreak. Recommended hooks control the access to more classes. Extra hooks include toggles for device check framework, match lookups, symbolic lookups, low-level C handles, and anti-debugging. All features can be configured globally or per-app settings.

Shadow Tweak's last update was in 2019, during the iOS 12 era. However, the developer has recently revitalized the project by introducing new features and supporting newer iOS jailbreaks. As of now, the tweak is compatible with modern iOS 11 through iOS 15 jailbreaks. Therefore, you can install the tweak and use it on Palera1n-C and XinaA15 on iOS 15.

Info: XinaA15 Jailbreak is packed with LinTui, a built-in jailbreak detection bypass for iOS 15.0 – iOS 15.1.1. If it doesn't work for you Shadow jailbreak bypass tweak can be a solution.

In most cases, there is no need to manually configure all of the jailbreak bypass detection settings. However, it is a useful feature to have the ability to exercise full control over how the tweak operates. Tweaking those settings can be more efficient to run an app on a jailbreak.

The latest 3.0 release brings some great features and improvements to the jailbreak bypass tweak. The developer added jailbreak detection bypass configuration per-app, and improved tweak performance. It is also iOS 15+ rootless-ready for Procursus-based bootstraps.

What's more, with Shadow 3.0 there is no more static file map generation, jailbreak files are detected dynamically, and tweak compatibility is improved. No more conflicts with tweaks that rely on jailbreak files (e.g., theming). Preferences features more options for hook customization.

Shadow tweak uses now the HookKit Framework as a dependency. This not only enhances performance, but also enables users to alter hooking methods in order to potentially evade detection. In addition, support for rootless jailbreaks has been improved, and preference pages have been reorganized. A new feature, the Extra hook App Enumeration, has also been added.

The developer also included new hooks for avoiding jailbreak detection. Device Masquerade (spoofing device as M1 Mac that may bypass some checks entirely), Loaded Modules (takes over a lot more dyld methods), and Runtime Class Lookups (filters low level objc lookups).

Shadow jailbreak bypass tweak for iOS was released as an open source project thought GitHub under BSD 3-Clause licensing. The tweak should work on iOS 7 and up. However, the developer will drop support for < iOS 11 as Apple's developer API evolves.

Alternatively, you cat download other jailbreak detection bypass tweaks for iOS. There is KernBypass tweak (kernel-level jailbreak detection bypass), A-Bypass (automatically disables jailbreak detection), and vnodebypass that allows you to run most popular game hacks on iOS.
