    Hi. I've just rooted my Galaxy S6 device and now, when I try to update it, it tells me that the operating system in my device has been modified in an unauthorized way. Any help please?

    Welcome to the forums!

    The unauthorized modification is rooting the phone and you can't do an update OTA or via Kies, on a rooted device.

    You must unroot and if you flashed a custom ROM, you have to go back to stock, then you can update.

    This is what I know. I had to unroot and then flash an official ROM to upgrade OTA, and I never did custom ROMS on my phone.

    Let me get someone that has more knowledge on rooting, as I have only rooted once, a while back.

    Welcome to the forums. Kelly flagged me down for this thread. Flashing the newest ROM with Odin should fully unroot you, and it also should remove the modified system flag.

    Did you only root? If so, can you just unroot it?

    Something came up after posting...make sure you look for your exact model number for your files. Flashing the wrong ROM can lead to a bricked device.
