      I am using SM-G530H India country for my prime SM-G530H Indonesia. It ok, there is no problem. You now, what different between India firmware and Indonesia firmware is only on languange. In india firmware there is no Indonesia languange. This is the same with SM-A300M firmware Argentina and Ecuador. But If you doubt to update it.. don’t do it.
