    100% working.....

    First back up your Data as you have to reset later.

    Download file from this link according to your mobile....

    https://www.oneplus.in/support/softwareupgrade

    After downloaded change the file name by removing .jar from last sentence of name and last word of rename should be .zip otherwise it doesn't show in local upgrade of system update.

    Then move the file from Download folder to Internal storage (Don't paste it inside any folder)

    Go to system update and click on local upgrade choose the file and it started downgrading.

    When it completed you have to wipe out data then reboot.

    Congratulations you successfully downgraded...
