Help please! 110$ re450 bricked!

Hi,

The reset button is not doing anything, all leds still flashing intermittently.

I followed exactly the instructions on to reflash the original firmware given here: https://wiki.openwrt.org/doc/howto/generic.uninstall

This is what I did after sshing into the router:

cd /tmp
wget http://www.example.org/original_firmware.bin
mtd -r write /tmp/original_firmware.bin firmware

Is there any hope of recovery or is it paperweighted?

Thanks!

EDIT:
Just thought I will provide a little more info: Even when I connect wire ethernet to the router, the connection keeps going on and off. Probably a bad sign. Not sure.

All help appreciated. Worst case scenario I'll try and return to Amazon.
