No way to acess menu buttons on recovery mode - SM-T530NU

my SM-T530NU running on Android™ KitKat 4.4 has a "Device memory damaged" problem. I tried to factory reset via recovery mode but when I enter the recovery mode (by pressing power, volume up and home buttons) I only see the Android guy laying down with the exclamation point but without the menu options. How do I get the menu buttons?! That way I could reset to factory mode and it would be okay again! Thanks
