Nighthawk AC2300 firmware update fails

[Toi-Gye]

I connected to the router through a pc to update the firmware. after the router had downloaded the latest update, it started installing and rebooting. but now only the power light flashes and I do not get access to the router.
It does not help to press the reset button. Nothing happens.
please help.

Sounds like something must have happened during the update. 

You can try recoving it 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
