    Hi, I just got one Yuandao N12, it has two usb ports, 7" screen and so on. I think it had android ice cream sandwich.

    The thing is that I played around with it for about an hour, the battery had about 80% when I started playing.
    While looking through a pdf file the screen froze while I was adjusting the screen brightness. I hold down the power button to shut it down and it hasn't started since.

    Nothing happens when I plug it in to the computer with USB cable.
    Nothing happens while I load it. (which polarity does the DC charge have btw?)

    Pressing down the power button you can sometimes see the screen get "black" and it shuts down as soon as I stop holding down the power button.

    Does anyone know any tricks, button combinations that will help, firmware or something?
    Since nothing shows up when I plug it into the computer I can't really use any of the software from this site?

    Maybe reflash the firmware? It could be a corrupted fw or try a factory reset?

    Hi, thanks for the reply! Currently I am looking at my yuandao with it's back off. Can't see anything out of order. How do you factory reset?

    One problem is that I have never gotten a response that I have plugged in my tablet in my computer so it seems I can't do any "software" changes. But I might just suck.

    Hie. have a pronlem with my yuandao/
    window N12. it is a rockchip 2918. it
    started of by not booting up. it would
    end with displaying a logo. so i got the
    firmware from a site and the flash tool.
    it had every part except the kernel. i
    was able to write the new firmware to
    it abd it would say "run ok". but then it
    was suppised to finish on its own.
    when i pressed the power button it
    would light up a completely black
    screen. just showing the backlight only.
    i repeated the process a couple of
    times and now my pc can no longer
    detect it. says "the device is not
    recognised" is there a way around this
    and what did i do wrong to get there
