• Downgrading One UI from 6.1 to 6.0 on a Galaxy S21 Ultra is risky but possible using Odin to flash downloaded firmware.

• This process requires backing up data beforehand and may void the warranty, disable features, and expose the phone to security vulnerabilities.

• Incorrect firmware can brick the device.

• Professional assistance is recommended.

You can do this on the computer, but I advise you to go to a phone shop to do so and be a mobile professional.
