Ref: The Open Wrt firmware includes a Failsafe Mode which may be used to recover from a variety of problems associated with flashing mis-configured firmware on to a device.
- Apply power and wait until the System LED first flashes, then press and hold the Reset button until the System LED flashes very fast.
- Release the RESET when the LED starts flashing quickly. On the WDR4300 device, push the Reset/WDS button briefly and repeatedly after switching on the power.
The System LED (star shaped next to power LED on left) will start to flash very fast when the device enters Failsafe mode. The indication of the correct time to press and hold the Reset button can vary with different devices depending on what LEDs they have activated.
Some devices, including the MP02, do not activate the LEDs at all for Failsafe mode.
The following describes how to use the Failsafe mode for the MP02 and various TP Link devices used for VT SECN mesh nodes.
The Failsafe Mode may be activated by pressing the reset button on the device while the power power up sequence is happening.
