R6400 Failed Firmware Update-Corrupt
I have a R6400 AC1750 router. While attempting to update to the latest firmware version, the update failed. Now my routers internet light constantly flashes amber and the power light doesn't come on, ...
- I contacted Netgear support to get a RMA # so I could get a warranty replacement. Before receiving my RMA #, the support agent had me troubleshoot several different ways in an attempt to communicate with the router. After about 1 hour on the phone I got the RMA and now have a warranty replacement in my possession. Just a FYI, the troubleshooting was free of charge and I only had to pay shipping cost for the replacement, $17 for advanced shipping method, this covers shipment to you and shipping of the defective unit back to them.
Hi Simarti28,
There is no need for you to unzip the .chk file since that will be the firmware itself. Just make sure you have downloaded the correct firmware version for the specific router model. You may refer to the link below for the steps on how to perform TFTP.

DexterJB, I forgot to ask.....when I'm updating the router manually do I connect the Ethernet cord from my PC to a LAN port or the WAN port on the router? Also, does my PC need to be connected to the Internet at that time?
Thanks,

First of all what caused your router bricked? Did you get any error message? Was doing it on wireless connection? Or you did something stupid to the router B4 updating finished? In a situation like this, first thing you should do is to figure out what state router is in.Disconnect everything from router except one LAN connection to your PC, then see if you can access the router, if not run 'ipconfig'
command to see what gateway ip address is. ttfp needs precondition for the router, it does not work no matter what the router status is.
You trying to update again? Then your router is accessible?
I was updating wirelessly, now I know that this is not recommended, but when I went to update it said "ensure that you are connected to your router wirelessly or via Ethernet cord" so I figured wireless would be fine. If it's not recommended to update through wireless then they should change that message when you go to update. I did receive an error message with a sad face icon on a piece of paper. I don't recall the exact message. Ipconfig does not return an IP address nor can I ping the router. I'm not home now but will try tfpt later tonight or tomorrow and reply back.

You should disconnect the router from the everything except power. Then connect a PC to one of the router's LAN ports. If your PC fails to get an IP address, then the router is probably not booting up properly. In this case, you will have to recover the router by installing new firmware using TFTP.
You can follow Netgear's instructions for using TFTP (link). Follow the instructions carefully to statically assign an IP address on your PC. Don't forget to revert this after you recover the router.
Windows has a built-in TFTP client, so you don't necessarily have to download the ones suggested in the article. See here for details to enable it.
