About a week ago I bought
this no-name HDMI dongle to connect to wirelessly with my tablet. However, it very quickly froze and right now is only showing one single image on any TV I try it with. When I connect it to my computer (Windows) it shows up as "rk2928sdk". My question is can I restart (so to speak) or revert the dongle to its factory state using some computer tools? I don't want to send it to the manufacturer.
