Nighthawk R6230 bricked after firmware upgrade

After performing the firmware upgrade (104, I believe) the router shut off and never rebooted. The picture shows how the router looks. After 30/30/30 reset the two lights I circled will alternate flas...

there is one piece that I would like clarification on...  some of the instructions mention to hold in the reset button while powering up the router just prior to downloading the firmware.  some do not.  what is the correct method?

 

when I hold reset while powering up, the power led stays solid green and the wi-fi and network led's blink back and forth continuously until the router is powered down.  is this the correct behavior for the download for this specific router?

it could be a hardware failure. Did you try nmrpflash?

    Hi all - I am on a mac and after a day of banging my head against the wall, I was able to get my router back working by rebooting the firmware via nmrpflash. Woohoo!

    https://github.com/jclehner/nmrpflash

    Note that with nmrpflash once it successfully connected, all lights turned off except the internet connection light. That was how I knew it was working, whereas before I either just had the power light, or the power light + wifi/internet lights blinking back and forth.

     

    I am on a mac and will put the instructions in my other post on how to use nmrpflash because it took a lot of guesswork to figure out the commands.

    Also, as soon as I rebooted there was a new firmware available, I bet Netgear realized they were bricking routers and fixed it...

    I will give nmrp a try, but I'm not a network/IT guy and the instructions looked a little foreign to me. Any more help on how to use this method?

      i'm in the same boat...  the linked nmrp instructions scared me off.  too intimidating for a greenhorn such as myself

    Just to update I have tried tftp.
    I have downloaded tftp via the links and followed the instructions in the YouTube video. Wifi is disabled, file is unzipped, ethernet port set to static ip and detects the router. Router is turned on with ethernet cable from computer plugged into LAN1. Tftp is enabled on the PC. I keep receiving unable to get responses from server as the end result. I also tried running it using the command prompt with connect request failed as the end result.

    More detailed direction of how to use nmrp flash would be appreciated as I will need a new router if I can not make this work.

    Sounds like another on this thread has had the same issue as me... very frustrating
