## What it is
A cross-platform command-line utility that uses Netgear's NMRP protocol to flash firmware images to Netgear routers and other compatible devices, primarily for recovering bricked hardware. It works over a directly connected network interface and uploads firmware via TFTP.

## Use cases
- unbrick a netgear router
- flash firmware to a netgear device over ethernet
- recover a router that won't boot after a bad firmware update
- install custom firmware on a netgear router
- repair a bricked wifi extender

## When to choose
- you have a Netgear (or NMRP-compatible) device that is bricked or refuses normal firmware updates
- you need a free, cross-platform recovery tool with prebuilt binaries for Linux, macOS, and Windows
- you want to flash firmware over a direct Ethernet connection without opening the device

## When to avoid
- your device is not a Netgear or NMRP-compatible product
- you need a graphical recovery tool rather than a command-line utility
- the router still boots normally and supports standard web-interface firmware updates
