Emergency room
« on: December 18, 2016, 11:56:10 am »
When bricked one must normally resort to the use of a UART to access the internal serial port,
but D-Link have implemented a clever 'Emergency Room' which is a Web interface for loading
firmware to a bricked unit.
  I find this an amazing feature that makes for a much more robust unit, and wish all routers
used this feature. To invoke this on a D-Link router:

Setup your PC with static IP on subnet.
Open your web browser and get it ready to connect to
Press and HOLD the reset button on the router and connect power. Hold the reset button for about 3~5 seconds, then release.
Connect the browser to . The Emergency Room Updating Firmware screen should display.

Asus routers have both a TFTP restore and an HTTP restore mechanism...
Still good practice to reflash even after the TFTP restore... 

Supposedly the Almond 3s have a fallback mechanism if the flash upgrade fails.. iv seen it..

But yes.. not requiring the serial console port... priceless =)
