We also published a tutorial on how to get Oxygen OS 11 onto T-Mobile OnePlus 7 Pro by converting it into an international variant; that is until the device finally got Android 11 officially from T-Mobile.
It also fixed the issue where audio is routed through speaker phone. The changelog is similar to the Oxygen OS 18.104.22.168 released for the international variants.
