OnePlus doesn't always provide download links for all of their OxygenOS firmwares.

1. First, download the OxygenOS full firmware file you want to install.
2. Connect your OnePlus 8T to the computer and transfer the upgrade package to root directory of the phone’s internal storage.
3. Once the file has been placed in the correct location, open "Settings" menu and scroll down to the bottom.
4. Select "System" and then "System updates".
5. Press the cogwheel icon on top-right of the screen and select "Local Upgrade" option.
