    I've tried to root my phone a while back because I needed to use a different sim card. Now I can't update the software anymore. I keep getting: "The operating system on your device has been modified in an unauthorized way. Try downloading software updates using Samsung Kies on your PC or visit a customer service center."

    Any idea how I Can fix this?
