Hi
I try to upgrade new firmware from Luci web page because it is easy, I think.
What I did was I choose the .bin upgradable file under 'Flash new firmware image' and press 'flash image' button. But not successful.
Error message said
"The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform."

I checked how to upgrade wiki page and information is not up to date and not relevant to my situation.

How to convert to supported format?
