Debricking Buffalo WZR-HP-G300NH

This is a Vagrant configuration made for flashing a bricked Buffalo WZR-HP-G300NH router using TFTP. Tested on Windows 10 environment but should work on other operating systems too.

Prerequisites

• Bricked Buffalo WZR-HP-G300NH
• A spare working router/switch
• Two Ethernet cables
• PC
• Vagrant and VirtualBox installed

Usage

• Checkout this repository
• Connect PC to the working switch using Ethernet cable (did not work over WiFi for me)
• Connect bricked Buffalo router's LAN 4 port (closest to the WAN port) to any port of the working switch
• Download V24-SP2 build 14998b version of firmware from here.
• Extract downloaded archive to files\wzrhpg300nh-pro-v24sp2-14998b
• vagrant up
• vagrant ssh
• Plug in router power cord and run /vagrant/flash.sh. After around half a minute you should see a similar output:

[vagrant@localhost vagrant]$ /vagrant/flash.sh
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 11.8M    0     0  100 11.8M      0   478k  0:00:25  0:00:25 --:--:-- 1092k
100 11.8M    0     0  100 11.8M      0   478k  0:00:25  0:00:25 --:--:--  478k

• Wait while router reboots (DIAG LED stops flashing)
• Go to http://192.168.11.1 to confirm that firmware installation was successful

NB: If you're changing flash.sh from host, use vagrant rsync to synchronize your changes to guest OS.
