    I had the same issue, I have updated the Hydrogen on the phone and then you get the error of cant downgrade
    I am not sure exactly what happen but it worked, try and follow these steps
    1. Downloaded the oxygen file from OnePlus support for OP6
    file name - OnePlus6Oxygen_22_OTA_027_all_1810260000_bbefbe028ace46e5.zip
    2. Connect the phone to comp and place the file in root dir, (When connecting the phone you need to allow file transfer from the USB menu that you have), (root dir = open internal storage on comp and then you are in root)
    3.use this link to unlock bootload -
    4. In System updates - open the option for local update and select the file you placed earlier
    5.Reeboot the device and you should have Oxygen
