Installing the Serotonin semi-jailbreak is a straightforward process, and I'll guide you through each step. From downloading the Serotonin IPA to installing the jailbreak using TrollStore, and configuring RootHide Bootstrap for tweak support on iOS 16, this guide covers it all.
Serotonin, developed by hrtowii, stands out as a fascinating project to serve as a non/semi-jailbreak solution for 16.0 through 16.6.1, iOS 17 is not supported. Leveraging the KFD exploit and RootHide Bootstrap, it intelligently addresses launchd hooks in the posix_spawnp of SpringBoard.
When you install Serotonin Jailbreak in the background it runs its own SpringBoard, using springboardhook to load tweaks and the Ellekit. This allows RootHide Bootstrap to run some of the best Serotonin tweaks for iOS 16. Follow this guide to install Serotonin semi-jailbreak and unlock more features on iOS 16.
In my opinion, this is a truly fascinating project that lets you enjoy jailbreak tweaks without actually jailbreaking your device. It could very well be the future of jailbreaking where fewer exploits require to be use.

Serotonin Jailbreak was released as a TIPA package that can be downloaded for TrollStore. Alternatively, use the direct Install to download the app automatically with TrollStore. This feature requires you to enable the URL Scheme from TrollStore Settings. v2.0 comes with a new UI, but it doesn't work. Use the regular version instead.
Requirments
Serotonin Jailbreak serves as an advanced SpringBoard tweak injection toolbox for arm64e and arm64 devices operating on iOS 16.0 through 16.6.1. Compatible with a broad range of devices from iPhone XS to iPhone 14, this powerful jailbreak empowers users to install jailbreak tweaks, transforming the aesthetics and functionalities of the Lock Screen, Home Screen, and Control Center. Serotonin does not require a jailbroken environment.
This platform functions similarly to KFDmineek, enabling users to leverage Bootstrap from RootHide, ElleKit, and the TrollStore installation method. For Serotonin app usage, make sure your device is operating on one of the mentioned supported versions and has TrollStore installed. Please be aware that Serotonin for iOS 17 is not available; however, support for iOS 16.1 and lower was added with the release of the 1.0.1 version.
RootHide Bootstrap can apply tweaks to nearly all apps, although it lacks support for springboard tweaks, including those affecting the Home Screen, Lock Screen, Control Center, or Status Bar. Nevertheless, installed apps and jailbreak tweaks for system apps, provide configurability directly from the Settings app.
After installing the Serotonin Jailbreak, you'll see a new icon on your Home Screen. To make sure the app runs smoothly, ensure that Developer Mode is enabled on your device; otherwise, the app may not launch properly. It's important to use TrollStore for installing Serotonin, as it's specifically designed for this environment.
Serotonin works by automatically replacing launchd, patching launchd hooks in SpringBoard, and running its own SpringBoard with springboardhook.dylib. This process allows you to activate tweaks like TrollPad, Atria, BetterCC, and more through Sileo and RootHide's Bootstrap.
The app has a simple and user-friendly interface that makes it easy to access all features and settings. Compared to KFDmineek, Serotonin offers a fresh UI design and additional features, including options to reinstall Bootstrap or restore your system.
In the settings, you can customize things like puaf pages, set static headroom, enable verbose boot, display exploitation output, and adjust the app’s appearance. There's even an option to switch back to the older graphical interface if you prefer.
Serotonin Jailbreak was released as an open-source project, with all its files available on the Serotonin GitHub Repository. The project is primarily written in C, with some additional files in Swift and Objective-C. However, it appears to have been discontinued, as there have been no updates since January 2024.
Because Serotonin was released as an open-source semi-jailbreak, a new project was released based on its source code. NathanLR is a non/semi-jailbreak solution for iOS 16.5.1 through 16.6.1, based on the Serotonin developed by hrtowii. Its key advantage over the original fork is support for rootless tweaks, making it compatible with most Dopamine Jailbreak tweaks. Additionally, there's no need to use RootHide Patcher to convert tweaks.
Serotonin can be installed on your device only through the TrollStore or TrollStore 2 IPA installers. When using other tools like Sideloadly, AltStore, Bullfrog Assistant, and Esign the jailbreak will not allow you to execute the KFD exploit. Please be aware, that iOS 17.0 is not supported. You can install the Serotonin on iOS 16 only.
