Try this:
https://kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTPNeed to press the reset button for 30 seconds then release, then it send to PUT the command and upload the FW.&nbsp;Make sure you enable tftp: https://www.thewindowsclub.com/enable-tftp-windows-10Video 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:https://www.youtube.com/watch?v=R9DLrLQrpawI had a problem on a Windows 10 PC where this didn't work to use TFTP, so I switched to a WIndows 7 PC and the TFTP worked.Mac TFTP: https://www.petenetlive.com/KB/Article/0001247Try nmrpflash:https://github.com/jclehner/nmrpflash

Finally I had the time to try your recommendations&nbsp;FURRYe38. Unfortunately, it didn't work.&nbsp;I've tried to use tftp on Windows 10 and 11, and also the nmrpflash through Linux. No luck on any of them.&nbsp;One thing that I noticed is that ports 1,2, and 3, it doesn't get a stable network connection, they keep connecting and disconnecting. Only ports that get a stable connection are 4, 5, and 6, and they blink white when they do.&nbsp;No luck also trying using the IP range 192.168.0.x. All the recommendations had the 192.168.1.x.&nbsp;If you check the video, you will see that the ports 1,2, and 3, keep blinking that amber colour.&nbsp;Any other ideas?&nbsp;&nbsp;
