So, my roku I just got it from somebody, I plugged it in, then it pops up the roku loading up menu or loading screen, then after a couple seconds of it, it starts blinking white, after 8 blinks, it turns off, then I can’t turn it on until i un-plug and plug back in, I have tried resetting, trying diffrent cords, same cords that came with it, and updated and factory reseted it from recovery mode.
