Updating Roku account information
Unfortunately, there is no specific menu options to remove or change the account assigned to a Roku device. This is because all of the configuration settings of a Roku device are assigned to and associated with a single Roku account. So your only option is to reset the device, which is basically equivalent to removing the Roku account assigned to the device. There are three ways to do this.
First, you can do a complete factory reset of the device (Settings->System->Advanced system settings->Factory reset->Factory reset everything).
Second, you login to the Roku account online (https://my.roku.com/account). Then select the target device under the "My Devices" section of the web page. This displays the Device details page. Then select the "Remove device from account" link.
Third, you can install the iPhone or Android Roku application on your phone. Then open the app and login to the Roku account. Select the "Account" icon on the bottom right corner of the app. Then select the "Devices in account" icon on the top left cornet of the app. Finally, select the target device, and click on the "Remove device from account" link.
