Downgrading S8

[hamslice]

I have a Galaxy S8 with the model number SM-G950U, It is on the most recent Oreo update and I would like to downgrade it Nougat. I want to know if it is possible to do?

I am worried that because its an SM-950U on Oreo that it isn't possible because of the locked bootloader but I am unsure. Every tutorial wants me to unlock OEM in developer tools but my phone doesn't have a toggle for the OEM under developer tools.

Tutorials for the 950U, or tutorials for a different variant? Following the tutorial for a different variant can brick your phone. The U isn't the F.

Are you sure you can't sort out the problem another way? Having Oreo has more advantages than Nougat. What makes you want to downgrade?
