Revert to stock firmware Belkin AC1750DB

I have a Belkin AC1750DB router running LEDE Reboot 17.01.3 r3533-d0bf257c46 and would like to revert to the stock Belkin firmware. I have located the firmware on the Belkin site and downloaded it but I am having some problems loading it through the Luci gui. Can anyone tell me how to accomplish this?

Thanks in advance

See the instructions for the Belkin AC1750DB (F9K1115) here...

Thanks for your reply Jim. I had been here but what I am trying to do is
to revert to the original firmware and I find no directions on this page
for doing so. Ideally I want to revert using the gui to reload the
original firmware but there seems to be a file incompatibility with the
stock firmware .bin file so maybe I need to do some type of file conversion.

Thanks in advance for any help you can provide.

I normally use TFTP when the GUI method doesn't work.

I believe there are some instructions on TFTP in the Belkin OpenWRT link.

Thanks Jim. I was hoping for simple and hopefully foolproof.

Silly me:<(

Any reason you know of the mtd method wouldn't work?

Lots of tutorials on YouTube on how to use TFTP.

I have not used MTD.

Thanks Jim. I appreciate your help.
