This method works for downgrading from the 380 firmware version that doesn’t allow you to use the form to downgrade, which is really useful. It also works if you fucked up your router and it just keeps booting into rescue.
I’ve only done this on my RT-AC68U so IDK about other routers. I’d assume it’d work for basically any AsusWRT router if you make sure to google how to go into rescue mode on your model.
With your computer plugged into the ethernet port on your router, change your ethernet adapter IPv4 settings to manual, IP: 192.168.1.10, subnet: 255.255.255.0.
- Power off router.
- Power on router while holding reset until the Power LED starts blinking. (this is for n66u, it might be different for your router)
- Go to 192.168.1.1, you will see a image that says CFE Miniweb server and a firmware upload form.
- Simply upload the firmware file you want (I used Merlin 376.48_3)
- Click upload and after it’s done uploading it will say to wait a few moments for the router to reboot, this can take up to an hour (and probably will! be patient!).
- You’re done! Change your IPv4 settings back to auto DHCP.
