Factory reset a woo tablet I tried to reset a woo tablet 7" without success:


When pressing [Power button] + [Volume Up] I can see the android icon with the warning icon but nothing happens!
pressing [Power button] + [Volume Down] opens a weird menu in a korean-like language.


How I can perform a factory reset on a woo 7" tablet?

Update

I can't access to the tablet, it's locked with gesture pattern.
Power Button + Volume Up
Volume Up, select recovery mode 
Open with Volume Down
Volume Up or Volume Down to select wipe, then Power Button to execute
