Hi
I got this ZTE zxhn f680 ONT from a friend. He said he doesn't need that, if I have any use for that.
So I took it and the problem is this device was from an ISP, they got its firmware modified so many options are removed from the firmware and so I cant use it.
I searched the official firmware, but Its no use.
Can anyone provide me information if there is any firmware available for it?
