Samsung Galaxy S9+ firmware update help

ok gotcha, i will try the SM-G965U1 version.

I am not sure where on the xda forum to find the Odin tool. I've tried searching and found threads from 2013 and 2018 saying the latest version is a patched Odin 3.13.1, which is obviously older than a 3.14.4 that i found elsewhere. Any tips? Just not familiar with the XDA forum. Also now i'm not sure if 3.14.4 is legit....?
 
I used the patched 3.14.1 version. same issues as before trying to upload the firmware for G965U. Will try G965U1 next
 
Update: Using patched version of 3.14.1 Odin, and the files Frija obtained using the G965U1 model firmware, i had the same issue. It is failing with "Complete(write) Operation Failed"
