Stuck with a black screen

Hello, everybody. It's my first post and guess what ? i think i bricked my brand new Haipad m701-R. I bought it to develop some apps on a beautiful big screen, like i'm a geek yesterday, i tried to update the firmware because it was the original firmware. Something went wrong, i don't know what but now i'm stuck with a black screen on the tablet and with a big scary error of death on FWDN 2.10.
I would like to know if someone can tell me what to do because i'm starting to think that this tablet gonna go through the window very soon
Thx for your help.

 

When i turn on the tablet i have a beautiful black screen no boot logo or things like that . I heard the windows sound saying that a new device has been connected so the tablet is definitively started but nothing appear.
