Unable to flash openwrt image

I have a netgear r7800. I am currently running dd-wrt. I've tried flashing stock netgear firmware (the latest version and the first version released), which failed. I then tried just flashing the openwrt image, R7800-owrt2512-r32353-9e9b05130c-20251219-1738-factory.img, and it just takes me right back to dd-wrt.

Maybe it's best to ask the people on the DD-WRT forum how to go from their firmware back to stock.

You don’t have to flash stock firmware to flash openwrt. You just have to press and hold power button for 15s while you power it on, once you see the power led blinking in white the unit is in tftpd mode. Then you just need to connect a client computer to the lan port, set ip of the client to 192.168.1.2, then run these commands:

tftp 192.168.1.1

binary

put nameoftheopenwrt-factory.img

Now it will reboot and openwrt is on it.
