mobile

I want to convert my T-mobile (sm-g925t) to the international version so I can get OTA updates faster thatn T-mobile users. I know I can just flash International ROMs but I'd rather have the stock firmware instead. Does anyone know how to convert from T-mobile to International? is it even possible on Galaxy devices? I've done a tone of research and I haven't found anything that can help me with this. It is possible to do this on HTC devices, for example I converted my T-mobile HTC One to Developer Edition HTC One by changing the MID and CID, but I don't know about Samsung devices.
