Device doesn't start Android - Stuck in Recovery menu

Hello.

I was experimenting with an Android tablet: http://www.innjoo.com/ProductDetail/F3/Technology and I must have messed things in the Android system because it won't start anymore.

When powered On normally, it's stuck on the Manufacturer logo.
When pressing Volume Up + Power for a moment, I have access to three options:

• Recovery Mode
• Fast Boot
• Normal Boot

I tried factory reset in the Recovery Menu, but still no results and after reading some pages on the great Internet, it seems that "flashing a ROM" is the only solution left.

So I would like to have experts advices on how I should properly do that before trying anything, since I read that some manipulations may have cataclysmic consequences.

PS: If there is, by any hasard, a way to run a Linux OS ( like ArchLinux... ), could you also let me know how to do it.

Thanks in advance.
