    Make sure you have already downloaded the Android 11 Rollback installation file, and removed the .jar extension so it ends in .zip, place the file in your main storage away from any folders.

    Once you have downloaded the APK to allow the installation,
    https://oxygenos.oneplus.net/OPLocalUpdate_For_Android12.apk

    Install it then click on open you should see this screen.

    Click Open, then click on the gear wheel top right and it will detect the Android 11 Rollback file choose it and it will wipe your phone and allow the downgrade to take place.

    When the apk downloads, does the filename end with .zip or .jar, if so, edit the filename and remove that so it ends .apk.

    This is the apk file to use as the installer for the Full .zip OOS 11 downgrade file.
    https://oxygenos.oneplus.net/OPLocalUpdate_For_Android12.apk

    No, the APK file should end in .apk 👍

    Once you remove .zip from the end, the icon will change as per the pic below.

    Remove the .jar from the full OOS install file sinit ends .zip and ensure the file is then place in the main Root Storage of the phone. Make sure you have Backed up any data you want to save as this will Wipe the phone.

    Then use the APK file as per the steps given in my original reply to you to start the installation back to OOS 11. Follow the onscreen prompts.
