Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
If you are still unable to resolve the issue, please send me a PM with your Roku account email address, and include the serial number on the Roku device along with a summary of the issue you are experiencing. I'll be able to assist you further from there.
Are you able to use the remote when you first start setting up the Roku device? When you try to hard reset the device, are you making sure to press and hold down the reset button for at least 30 seconds regardless of what is happening on the screen?
With more information we will be able to assist you further.
