AC2200 Wifi Mesh Extender blinking green power light

Hi everyone!

I've read all the articles and watched all the videos and am striking out.

I have a Nighthawk ac2200 mesh extender which possibly has a firmware corrupted update. I've done everything I've read to reset the extender with no luck.

I run on a Mac OS and am unsure what to try next.

Any ideas or suggestions on how to get this back online?

This has happened one other time, but it did allow me to reset it with the 30-second reset, turn off and hold reset for 30 seconds, and back on and hold reset for 30 seconds.

That method hasn't worked this time, and the manual updates I've found are only on PC.

You can try recovering it with tftp or nmrpflash.
are you on windows? if so, follow this guide
https://kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTP
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.

What are the led's on it actually doing?

What makes you think its corrupted?

  Thanks for the questions! Sorry for being unclear on that.
  
  There is only 1 LED, and that is the power LED which only blinks. It won't reset, it won't connect to the network, and it only sits and blinks the power LED green.
