    Phone was working without any glitches until I updated it to oxygenOS 11.1.1.1 now it keeps hanging all the time and respond slow to UI and frequent crashing of applications. I would like to downgrade to previous oxygenOS version. Please help.
    Thank you in advance.

    Downgrading will involve wiping the phone. Why not try backing up the phone and do a full Erase All Data factory reset to refresh your current installation of OOS 11.1.1.1, see if it is any better.

    If you still want to Downgrade, the details are here.
    ROLL-BACK FROM CURRENT ANDROID 10 OR 11 TO EARLIER STOCK ANDROID 9 OR 10

    All Downgrades to earlier builds involve wiping the phone.

    So you will need to backup your phone data.

    Thanks to @ironass for putting this together and maintaining the thread.

    This Link will guide you through the Downgrade process.
