What Is Serotonin Jailbreak?
Serotonin is an iPhone and iPad semi-jailbreak application that allows users to install certain jailbreak tweaks without a full traditional jailbreak.
It works with RootHide Bootstrap, Sileo and ElleKit to enable supported Home Screen and system interface customizations.
Serotonin uses a special method to load tweaks into SpringBoard, the part of iOS responsible for the Home Screen and other important interface features.
You can install Serotonin through TrollStore on compatible devices running iOS 16.0 through iOS 16.6.1.
After completing the setup, you can explore supported tweaks, themes and customization options using Sileo.
However, Serotonin has limitations. It does not provide the same level of system access as a full jailbreak, and not every jailbreak tweak will work.
The Serotonin developers recommend using Dopamine instead when your device and iOS version support it. Serotonin is also no longer actively maintained for those devices.
