    After updated to 9.0.3 (23 January 2019 (OnePlus5)
    I am unable to unlock phone with the power button, nor with fingerprint. Screen stays black.
    When I restart phone then it ask for PIN, when I enter pin I am in phone and see all my icons and apps. Works fine. But when Locked again - screen stays black when trying to unlock it. Tried to Wipe data, cache, partition, but it problem persists.
    How to downgrade my oneplus5 to 8.1 ?
    Totally not happy with the v9

    Yap, I went via recovery back to fw 8.1
    Itcis so unfair that oneplus has hidden all older firmwares, you have to dig arround by some other sources to get to them.

    Hey, oneplus why no more older firmware archive?

    G_Devin_Hugo: this is not about unlocking because it was locked by operator, this is jut to turn on phone screen, and enter pin/swipe/ when in sleep... fingerprint has not worked either.
