The Nintendo Switch, while a popular gaming console, contains a hardware vulnerability in its early models (Erista chipset) that allows for arbitrary code execution via Recovery Mode (RCM). This paper details the methodology of utilizing an Android smartphone as a USB host to inject custom payloads into a vulnerable Nintendo Switch. Unlike traditional methods that require a dedicated dongle (e.g., SX Pro) or a computer, Android offers a portable, cost-effective, and software-defined solution. This paper explores the USB protocol requirements, the role of the fusee-gelee vulnerability, the software architecture of the injector application, and the step-by-step implementation process.
