    Best way:
    Do a factory reset before - update - and (to be safe) after the update again a reset :)

    Update to Oxygen OS 11.. it'll come directly to Widevine L1!

    Same issue like yours

    Update to Android 10!

    If it satisfies your L1 issue stay in Android 10

    Otherwise Upgrade to 11 i think it'll gives L1!

    No Need!!

    After Updating to Final Build do a factory reset through Recovery Mode
