This repository is a community firmware modification and reverse-engineering toolkit for Realtek RTL960x-based GPON/EPON SFP ONT modules. In practice, it is not a single application but a collection of vendor firmware images, patched root filesystem overlays, embedded WebGUI replacements, shell scripts, QEMU emulation helpers, and extensive OMCI/flash-parameter documentation. Users deploy the modified firmware and scripts onto SFP sticks to replace ISP-provided ONTs, clone ONU identities, enable 2.5GbE link modes, fix VLAN behavior, and expose device telemetry through Prometheus. The architecture is best described as a loose ecosystem of independent tools centered around the ONT's `flash get/set` and OMCI CLI interfaces, with no unified build system or runtime. The most maintainable software artifacts are intentionally self-contained: a Prometheus exporter in `WebGui/kitamon/` scrapes the ONU web GUI and publishes metrics; an emulator wrapper in `Tools/emulator/` extracts and repacks firmware images for safe testing outside hardware; and a reset script in `Tools/reset/` automates factory recovery over SSH. The rest of the repository is largely raw binary firmware dumps, modified `boa` web pages, and dated vendor SDK outputs. It serves a niche but active hobbyist/ISP audience, and while there is no CI or automated testing, the documentation breadth and practical utility are high. The main risks are legal sensitivity around ISP firmware dumps, dependence on old vendor toolchains, and potential bricking during manual flashing.
The LLM identified 3 files worth highlighting for reuse:
A standalone Prometheus exporter that scrapes the ONU's embedded web GUI and converts device status into metrics. It is import-light, deployable as a service, and designed for multi-target Prometheus scraping, making it reusable for any similar network device with an HTML management interface.
A shell pipeline that extracts, patches, and repacks RTL960x firmware images for execution under QEMU user-mode emulation. It encapsulates a reusable embedded-firmware experimentation workflow that can be adapted to other MIPS/ARM vendor images with minimal changes.
A parameterized factory-reset helper that connects to an ONU and clears its configuration partition, wrapping a dangerous vendor operation in a safer, repeatable script. The SSH-and-command pattern is portable to other embedded devices that expose root shells.
