Step 1: Download the Software and Set Permissions

Run the following commands from a terminal:

sudo apt-get update
sudo apt-get install wget
wget http://downloads.openwrt.org/kamikaze/8.09.2/atheros/openwrt-atheros-vmlinux.gz
wget http://downloads.openwrt.org/kamikaze/8.09.2/atheros/openwrt-atheros-root.jffs2-64k
wget http://ruckman.net/downloads/easyflash
wget http://ruckman.net/downloads/flash
chmod +x easyflash
chmod +x flash

Step 2: Set Up for Flashing

Plug in your Unit (meraki/accton/fonero) to your Ethernet LAN port on your computer using a CAT5e straight through cable (8P8C).

Type (from the directory where the files are located):

ifconfig eth0 up
./flash

(note: If your unit is NOT connected to eth0, modify
the file flash accordingly, it should be eth0 but you can check by
issuing ifconfig)

Step 3: Let the Flashing Begin!

Plug in the unit to power.

You should see something like this displayed:

Go get lunch. This will take 15-30 minutes, depending upon the flash
chip speed in your router. DO NOT INTERRUPT!

When it is done, the window will show Done.
