About:
nmrpflash is a command-line utility designed to recover Netgear network devices that are stuck in a boot loop or bricked. It implements the Netgear Mixed Reality Protocol (NMRP), allowing it to communicate with the device's bootloader over UDP to upload new firmware. This tool provides a reliable method for unbricking devices without requiring serial access.
Key Features:
  • Implements the Netgear Mixed Reality Protocol (NMRP)
  • Cross-platform support (Linux, macOS, Windows)
  • Simple command-line interface
  • No special hardware required, uses standard Ethernet
Use Cases:
  • Recovering a bricked Netgear router after a failed firmware update
  • Restoring factory firmware on a device stuck in a boot loop
Alternatives:
  • TFTP Server – Requires manual setup of a TFTP server and precise timing, whereas nmrpflash automates the protocol handshake.
