R6230 firmware corrupted

At some point my router bricked during a firmware update. The desktop I have is a pre-built gaming PC that does NOT have a CD disk drive installed. I can't put any disks into this PC. I've tried using the https://kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTP?_ga=2.241113669.737455280.1668025835-1979733303.1662605315 troubleshooting method, but when I type cd desktop into my command prompt, it doesn't find that directory path. Is there any other solution to upload firmware to a bricked router?

Additionally, when I downloaded the ZIP file, the format is not .img or .chk

    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
    https://www.thewindowsclub.com/enable-tftp-windows-10

    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. For sure watch this as it does a great job walking you through it

    and if that doesn't work, you can try using nmrpflash

    Do you get to the command prompt?

     

    Desktop.C Is one of those windows special folders that is buried in the depths of your system.

     

    You can put the firmware file anywhere you like on the drive. Pick somewhere that you can easily find with a series of "cd" commands.

     

    The first thing to go to:

     

    cd\

     

    That takes you to the top of the tree

     

    C:\>

     

    Then just drill down to where you put the file.

     

    You can even use Windows to copy the location, something like:

     

    "C:\Downloads\"

     

    Then "CD C:\Downloads\"

     

    Just play around. You cant do much damage at this stage.

     



    Additionally, when I downloaded the ZIP file, the format is not .img or .chk


    The file here:

     

    R6230 Firmware Version 1.1.0.114 | Answer | NETGEAR Support

     

    is a zip file that contains firmware in an .img formwt.

     

    What do you have?
