    You should be able to use the rollback package from this open beta 1 thread
    https://forums.oneplus.com/threads/oxygenos-11-open-beta-1-for-oneplus-8t.1400715/
    You can find them under "want to go back to MP, download the package below"
    After you have installed that you should be on a lower oxygen OS 11 version (don't know exactly which one) and then you can install whichever version you like, provided it is a higher build than the one you're on.

    This:
    Or use the msm download tool with the desired OxygenOS version: https://www.droidwin.com/unbrick-oneplus-8-pro-8t-msm-download-tool/
    But keep in mind: it will wipe your data

    Yep, that's why you have to back up all your data first. Switching from beta to stable always requires a data wipe.
