Re: T-Mobile 6T to International Conversion (WITHOUT unlocked bootloader/SIM unlock!)
Just to clarify Ryano89's answer, a local update on the global OnePlus 6T model entails downloading the new firmware to your phone from the official OnePlus download site and moving it to the root directory and then going to...
Settings > System > System updates > Menu (cog wheel)(screenshot #1 ) > Local upgrade (screenshot #2 ) > Select downloaded update (screenshot #3)
From there, the update installs and reboots the phone just like an OTA.

Screenshot #3
(Ignore the fact that it shows Beta in the screenshots. I just happen to be a Beta tester)
