Nighthawk AC2600 - Model R7450 -Will not come on after firmware update

[redhead56]

I did a firmware update last night and now the router has only one light on and that's the power button.  I've tried turning off and back on, unplugging, etc. and still nothing.  Has anyone else had this issue and were you able to correct?

You might have corrupted the firmware during the update. 

I'd first start with a factory reset. Push and hold reset for 7-15 seconds while its powered on. 

If that doesn't help, then you can try recovering with tftp or nmrpflash. 

are you on windows? if so, follow this guide

just make sure you enable tftp

and here's a video walk through using a tftp client. Use the built in one for windows 10 though. the video is more of an example of how its done.

and if that doesn't work, you can try using nmrpflash
