Simply Factory Reset the device. During setup, make sure to use the same email address as your other Roku account so everything is linked to that account. Just make sure you have a working Roku remote before factory resetting any Roku device.
To Factory Reset, either press and hold the Reset button on the device (sometimes a little pinhole), for 30+ seconds. Otherwise, Settings/System/Advanced System Settings/Factory Reset.
