(The Kabuto car in the bottom corner is optional ) I didn't have any switches or any other network appliance there, I just hooked the other end of the cable to my laptop and one end to the router.

WinRar packing utility from installed and working on your Windows.

Tool's filename is multicast_upgrade_tool.exe, 3354624 bytes.

A firmware file to upload, filename will be something like BV7R2C0update_.gz.bin.

An ethernet cable to connect the computer to the router's LAN-port.

To get the upgrade rolling you'll need following things:

Then normal boot process is stopped and the box will wait for a firmware file to be delivered to it. Turn power off from the device, keep WPS and Wi-Fi buttons pressed, kick on the power and at a suitable time release the Wi-Fi button. Getting the box to the upgrade mode sounds easy: If one could modify a firmware (and sign it), it would be possible to unlock locked devices, unlock features, or introduce new functionality.

For hacking, this opens a completely new avenue. In rare cases, hardware has an 'upgrade mode', which allows you to inject a new firmare to the device without any proper authentication. The obvious catch in that is, that you need to authenticate, move to a suitable page and upload a file to accomplish that. Typical firmware upgrade for any entwork applicance is done via web-interface.
