nmrpflash - Netgear Unbrick Utility
|
|
====================================
|
|
|
|
This program uses Netgear's [NMRP protocol]
|
|
(http://www.chubb.wattle.id.au/PeterChubb/nmrp.html)
|
|
to flash a new firmware image to a compatible device. This utility has been
|
|
tested with a Netgear EX2700, but is likely to work on many others as well.
|
|
|
|
### Using nmrpflash
|
|
|
|
Connect your Netgear router to your computer using a network cable.
|
|
Assign a static IP address to your computer (more specifically, to
|
|
the network card that's plugged into the Netgear router).
|
|
|
|
|
|
For this example, we'll assume that your network interface is `eth0`.
|
|
First, we have to assign a static IP address to our network interface.
|
|
In this example, we'll use `192.168.1.2`. All available network interfaces
|
|
can be listed using
|
|
|
|
````
|
|
$ nmrpflash -L
|
|
eth0 192.168.1.2 f2:11:a1:02:03:b1
|
|
````
|
|
|
|
Now we can start `nmrpflash`. The argument for the `-a` option needs
|
|
to be a *free* IP address from the same subnet as the one used by your
|
|
network interface. We'll use `192.168.1.254`. The firmware image file
|
|
can usually be downloaded directly from Netgear's FTP servers.
|
|
|
|
````
|
|
$ nmrpflash -i eth0 -a 192.168.1.254 -f EX2700-V1.0.1.8.img
|
|

### Building and installing
|
|
###### Linux, Mac OS X, BSDs
|
|
|
|
````
|
|
$ make && sudo make install
|
|
````
|
|
|
|
###### Windows
|
|
|
|
The repository includes a
|
|
[DevCpp](http://sourceforge.net/projects/orwelldevcpp/)
|
|
project file (`nmrpflash.dev`). Download the latest
|
|
[WinPcap Developer Pack](http://www.winpcap.org/devel.htm)
|
|
and extract it into the root folder of the nmrpflash sources.
