====== Recover your possible brick via Failsafe mode ======
The following HowTo is written for the MR3020, but usually the most OpenWRT based routers work in that way with the failsafe mode. 

YouTube video (demo): [[http://youtu.be/axQvgqvlhcU]]

  *  Connect the MR3020 to your computer via Ethernet.
  *  Set up your of the computer to ''192.168.1.2'' with subnet mask '255.255.255.0' (This step differs from OS to OS of your computer.)
  *  Start to ping ''192.168.1.1'' (this is the failsave IP) infinitely
  *  Power the MR3020 on and when the WPS Button starts to blink, push it (it will blink faster)
  *  You see the ping getting response
  *  ''telnet 192.168.1.1''
  *  run ''mount_root''
  *  Now you can edit files
