Tried to upgrade but something went wrong!!

Hi,
I bought my pandigital novel last week and was working fine. I decided to look on their website to check for updates and there was one for me.
I did everything that they asked for.
But I don't know what I did that now on the screen shows only a triangle with ! inside and the green robot.
I've been trying to turn it off but nothing happens!
Please, if someone here know what should I do I'd appreciate!!
Thank you very much!!

 

First, try to reset it with the little reset button. If that does not shut it down pop the back off and unplug the battery for a minute or two and plug it back in.

Download the update again and put it on your sd card and try it again. You might try it more than once, a few have had to with updates.

Which update did you try to use, there is a regular update and the open platform update.
