First try restarting both the Router, then the Roku device. If no luck, again press and hold that reset button for 30+ seconds. Additionally, make sure you are powering the Roku device with the power adapter plugged into a wall, not your TV's power port.
If still no luck, likely you have a failed device. If under a year, then should qualify for warranty replacement.

The underpowered Roku branded usb power supply is faulty. Notice the flickering power led. Interestingly, the boot up animation will play, but then goes dark. Just replace with another USB power supply. Preferably a more robust output of 2 amps (or greater).
