    S9 firmware problem

    Hi everyone !

    I need your help to deal with my Galaxy S9. I recently bought it online and thought it was new, quickly turned out it wasn't.
    At first I thought I made a mistake setting it up, but even if I'm a beginner with this I don't think it's my fault here. From what I can understand the firmware on my phone is the merger of a Vietnamese Android 9 version and something from the S9+ (screenshot of the Software Information page attached). Also the phone is rooted according to the app Phone INFO.

    It is still usable for the most part, but I can't download Netflix, use Samsung Pay or get any Android 10 update for instance. And if try to use the Camera, the phone just reboots everytime.

    That's why I need your expertise. Is there a way to "un-root" it and update it to the latest unbranded French (I believe the CSC should be XEF ?) Android 10 version of the firmware ? Should I seek Samsung's help or try to do it myself ? As I said I'm new to this and I don't want to mess everything up.

    Thank you very much for your time !

    Hi there

    Maybe other readers can help you with this, but we don't support ROOTED phones...

    Also you have a "Messed up" firmware;

    Our advice: return this device and ask for a NON-rooted / NON-messed device

    I totally understand that you don't support rooted phones, but I didn't know this one was when I bought it and I don't want it to be. I just thought there was maybe a way to bring everything back to normal. Thanks anyway, i'll return it.
