    After successfully rooted, I can’t get any official update from Samsung Software update option (Settings-General-About Device-Software Update). It says “Your device has been modified. Software updates are not available.”
    Now to do? Pls help. I want Official Update from Samsung all the time. Pls fix this issue soon. Eagerly waiting for ur positive reply.
    Without this issue, the device is running fine & smooth.
    Thank u for ur great contribution…

    • Now a prob. You need to flash a firmware back. If you can do it yourself, then good, otherwise wait for my link, which would take some time, maybe a day.

        Oh! Thank u @Kapil for ur reply.
        1stly I want to know that if I use Triangle Away, can I officially update my os successfully? Triangle aslo shows a caution that there is a chance of bricking the device! How much chances of bricking? I’m using Galaxy Grand 2 (Model No. SM G7102), Android 4.3. And I’ve successfully flashed for rooting my device with ODIN 3.09 two days ago.
        And finally my 2nd quary is if I update my os with KitKat 4.4.2 with ODIN, will my device get back its official update facility? Will the root facility then available? As already having a rooted device, can my root facility will continue with the next update automatically or will it be again rooted?

        Pls reply Sir…
