firmware-mod-kit

The Firmware Mod Kit is a comprehensive set of scripts and utilities designed for extracting and rebuilding Linux-based firmware images, primarily targeting embedded systems such as routers. Key features include the ability to deconstruct firmware into its components, modify the file system and web UI, and then rebuild the firmware for installation, albeit with a warning of potential device bricking. This tool is aimed at embedded systems software engineers familiar with the risks and complexities involved in firmware modification.
