Firmware error

Alvise

 I was installing firmware on a nbg6716.  When complete the router would not start up.  It is stuck with power light on and key lit up.  I cannot access the router even if I hard wire it.  I also have completed a reset with no sucesss.    Any help out there or is this router electric trash?
