Downgrading is not a standard OTA update. You are flashing software manually. Failing to prepare can result in a bricked device.
OnePlus officially provides "Rollback Builds" (downgrade packages) for users who want to revert from beta or stable Android 12/13/14 to Android 11.
Where to find them:
Example file name: Rollback_OxygenOS_11.2.10.10.LE15DA_210923.ozip
Copy the downloaded .ozip rollback file (do not rename or extract it) to the root directory of your phone's internal storage. Do not put it inside any folder (e.g., Downloads or Documents).
