The power LED (amber) blinks and will not stay on steady. I can no longer connect to the internet or to the router. I attempted to reset the router using a pin in the hole for 7 seconds. It did not work. I would appreciate Netgear support reaching out as the router is only 4 years old.

Ouch. This is well outside the warranty period, even in countries where it is more than the usual year, so you are probably reduced to TFTP.

There is more severe, recovery reset, that you could try:

• Press reset for 30 seconds
• Keep pressing reset while removing power
• Keep pressing reset for another 30 seconds while apply power

If it works, which isn't very likely, you may be able to use the usual method to flash the firmware again.

Download the latest firmware for your device – or an older version if that is what you want – and read the Release Notes for how to install it.

If that fails, you are into TFTP country.

This also explains how to tell Windows to use TFTP on your PC.

This isn't the easiest operation, so if you are forced to use it, you could try a web search to find videos that guide you through the process.

This one covers the process pretty well.

It applies to all devices and not just the one that features in the video

The good news is that TFTP has rescued many a dead device.
