I am looking the official firmware for the T-Mobile gold Samsung Galaxy s5.. I flashed a ROM and lost my backup of the stock firmware. I'm not sure what the exact firmware was! So I flashed 900TTMB1BNH5 firmware but now I can't do any system update bc of a unauthorized modification message and kies says its don't support my phone.. I am no longer rooted I did have root through towellroot with my stock firmware but now after I flashed the other firmware towellroot says my phone is not supported now.. So im thinking I don't have the right firmware install and my device info still says custom instead of official.. U didn't do a factory reset after the firmware flash in stock recovery.. Any help will be great full..
