    AVI44 , via OnePlus 6T , Dec 2, 2019 :
    I have updated my OnePlus 6T to Android 10 but after that I am facing lots of bug like Sone app is not working. I have tried to rollback to previous version of Android but every time i am getting the message System update failed. So please help me how to rollback to Android 9.

    Thanks in advance.
