Flash instructions:

You have three options:

- Use the vendor firmware upgrade page on the web interface and give
it the factory.img. This is the easiest way to go about it.

- If you have serial access during u-boot, interrupt the normal boot
(any key before timeout) and run 'run failsafe_boot'; this will bring
you to a minimal openwrt luci image on ip 192.168.1.1 useful if you've
bricked the normal firmware.

- Use the vendor's management cli, which can be accessed via telnet
with the same credentials as the web login (default admin:admin), then
issue the following commands:

*** Hi admin, welcome to use cli(V-1.6.7) ***
