Will this TWRP and Root method work for the
US T-Mobile Samsung Galaxy S9 Plus model: SM-G965U ?
I have seen many TWRP and rooting methods in the forums
which say they only work on the Exnos and not the US
Snapdragon processor versions of the Galaxy S9 Plus and exclude
certain model numbers including my SM-G965U.
I look forward to your answer.

Hi, It’s working properly for us.
Steve M. says
Is your Galaxy S9+ a US phone with the Snapdragon processor or another country’s phone with the Exynos processor? As I said above, the TWRP download webpage you provided the link for says TWRP will NOT work on a Snapdragon processor version of the phone. If your’s is a Snapdragon, and it works, that would be very good to know.

Did it work
Sathishkumar Varatharajan says
What kind of error are you getting? Let me know.
Thanks!

A followup to my prior comment – When I clicked on your link to download the S9 Plus TWRP, it stated that it was only for the Exynos processor version of the Galaxy S9 Plus.
Dennis Patton says
followed it verbatim….. had no effect at all. noted that root img is actually for a Note (8 or 9 .. cant remember) and not an S9. Root seems to install….. but on reboot, nothing changed and rootchecker says ‘no root’
