OnePlus 6 - System update installation failed

    Rohan.Arun , Jul 16, 2020 :
    My OnePlus 6 is running on very old Oxygen OS (5.1.10). Recently I wasn't getting any notification for updates. I tried to install the latest OS 10.3.3 manually by downloading from OnePlus website by following every single step. But when I select the .zip file and hit 'Install now' I'm getting an error 'System update installation failed' at 0%.

    Can anyone provide solution for this?

    Rollback .zpi file in the link is to downgrade from a beta version to stable version. My device is running on a older version that I need to upgrade to stable version 10.3.3.

    Anyways I tried to install the rollback .zip that is mentioned in the link but the issue still persists.

    ?

    Maybe you need to flash 10.3.0 first.
