    This has nothing to do with the file name, he hasn't used the correct roll back firmware.

    Make sure you follow the instructions in the first post of the Open Beta 1 thread (included below) and download the correct version for your device/region. Also, as stated in the instructions, roll back will wipe your device, so back everything up first.

    https://forums.oneplus.com/threads/...eplus-8-series.1296568/page-214#post-22148701

    Note: OBT is open beta, MP is Android 10
    OBT to MP rollback guide—via Local OTA update
    Note: This upgrade method will erase all the contents of the phone, please be sure to backup first
    1. Download the latest ROM upgrade zip package from the specified server
    2. Copy the Rollback package to the phone's internal storage, and remove the '.jar' file name extension if present so that the file ends in '.zip'
    3. Go to Settings -> System -> System Updates -> Click top right icon -> Local upgrade -> Click on the corresponding installation package -> upgrade -> System upgrade completed to 100%
    4. After the upgrade is complete, click Restart
    5. Update successful

    Want to go back to MP? Download the Rollback package from the links below:

    Download links for OnePlus 8:
    OnePlus 8 NA Version
    OnePlus 8 IN Version
    OnePlus 8 EU Version

    Try this, it should be a roll back package for Hydrogen OS to A10:
    The following are the downgrade packages available for downgrading to the stable version of Hydrogen OS 10 (Android 10):

    OnePlus 8
    http://download.h2os.com/OnePlus8Pr...all_2005301412_downgrade_336a08ea32aa4c88.zip
    OnePlus 8 Pro
    http://download.h2os.com/OnePlus8Pr..._OTA_0110_all_2009112319_2084a2d916f34549.zip
    They are from here:
    https://www.gizchina.com/2020/09/17...-os-android-11-public-beta-now-available/amp/
    I think you should then be able to download and install the latest 8 Pro software from your region's OnePlus support page > Software Upgrade.

    Download the file, move it in the root directory, so not in a folder
    Install it in recovery mode.

    that’s what I would try. Don’t know if this would work with hydrogen but I’d guess this would work

    al at your own risk

    Edit:

    I saw you want to go back from Hydrogen 11 to Oxygen 10 so this probably won’t work either. You’ll have to use TWRP I guess
