Gt-mt300n-v2 will not reset

My mango will not reset. I have tried holding reset for 10 seconds and releasing. I have also tried holding for 3 seconds.

It is plugged into power outlet and showing power light on. Other lights are off.

Using my Android phone, I am not seeing the default ssid (GL-xxxxxx-xx) or the ssid I created using the web interface.

The router was set up as a bridge and worked for a short time, but the wifi network I created using the mt300n is no longer available, which is why I am trying to reset.

Can u connect via Ethernet? Otherwise perhaps load latest firmware via uboot.
