Having trouble with LG G3 Android

[AC Question]

Hello, I bought a LG G3 D855 two years ago. I'm are yet to receive Android updates for the phone, it still has the Android Marshmallow it has always have. We use T-Mobile but they say they don't give updates for phones that weren't sold by them. How do I get updates for this phone? Thanks!

Welcome to Android Central! It sounds like you have the international version, which is why T-Mobile won't update it. You could try LG Bridge, but I'm not sure if that's compatible with the G3: LG BRIDGE - COPY FILES, AND BACKUP YOUR DEVICE
