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

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)

Let the Flashing Begin!

Plug in the unit to power.

You should see something like this displayed:
