Tablet won't boot up

Hi,

I just got an Arnova 10D G3 and it doesn't boot. All I get is the "Arnova" logo on a black screen. I bought it on a refurbished condition, it was a pretty good deal so I am ready to do any risky procedure to make it work since I don't have much to lose.

I downloaded the latest firmware from the official website but I am unable to use it because I can't access the recovery mode. When I try to, the tablet reboots while loading this mode, without even showing a menu.

When I connect the tablet to my laptop on Linux, nothing happens. On Windows 8, there is an "Android" device shown at the bottom (in the task bar), but the tablet doesn't appear as a drive.

How can I fix this?

Thanks
