I am attempting to downgrade my S9 from the One UI 1.0. 
SM-G960U
Updated all drivers, latest software/versions.
USB debugging enabled in Developer Options.
Option for OEM is NOT listed in Developer Options.
I followed a tutorial that stated: "If OEM is not listed, you do not have to worry about it" and another tutorial that stated "If OEM is not listed, it will block you from the root".
As such, I downloaded the latest TWRP and followed the steps in CMD. When I send it to all devices, I receive the error "access denied".
When I try to place the desired software on my device through Odin, I get the error "auth failed" immediately.
My phone has never been rooted before. It has the Samsung Official binary.

SM-G960U has a locked bootloader without the possibility of unlocking, which in turn means no root and no custom recovery either
