S1005KTAB problem

[Guest faji]

Hello, I own an S1005KTAB (tablet). When I tried to adjust the brightness to automatic by accident I pressed the 0% brightness. Since then the tablet is useless (blank screen). The question is if anyone has any idea how can I reset it to factory settings?

I managed to enter recovery but no menu in there!!! Any suggestions?

 

Thank you in advance :)
