Cannot turn developer mode off or change it

I have a UE50RU7450UXZT and i turned developer mode on in the 12345 way…
i changed wifi and so all my ip addresses.
now, i need to modify the developer mode panel /host pc ip… BUT
if i use the 12345 way the developer mode panel (turn on/of dev mode , ip etc…) does NOT pop up.
i cannot turn DEV MODE OFF or change it.
any suggestion?

Is there a reason you can’t just reset the TV? If not that should do it.
