CM2000 modem all lights flashing

I saw a similar thread for the cm1000, but I haven't seen anything for the cm2000. All lights flashing, unable to connect in any way. I tried unplugging, using the reset button, using other power outlets (it's been connected to a surge protected battery backup kit for months with no issue). Looks like a major malfunction. Anyone else deal with this?

    Only other thing I'd try would be this. 

    disconnect the coax cable. 

    while the cm2000 is powered on,push and hold reset for 30 seconds. 

    shut off cm2000 while still holding reset for 30 seconds

    turn the cm2000 back on while still holding reset for 30 seconds. 

    Then connect the coax and reboot. 

     

    If that doesn't work, it could be a hardware failure. click on "mynetgear" at the top. register an account and the device. that should tell you when your warranty is through

      Any fix to this issue or was it just hardware failure, because I just changed plugging it into a new surge protector after an outage happened and this same problem has now occurred to me where no matter what I do in any style or fashion of cable play/resets/waiting/new outlet/disconnect coax/ orientation of all that mixed, it still shows all lights repeatedly flickering super fast.

        The cm2000 is pretty new. it should still be within warranty. did you check it?
