Android Tablet start loop



so, I got mah TM703 ITWorks Android tablet, nice, but I somehow changed the tablet's resolution because I'm sometimes kinda stupid the tablet doesn't show anything now, except at the start(powerup) where it shows the start logo over & over like 5 times then there's nothing. the worst thing in all this shit is that I already hit the RESET button & it does ******* nothing. ironically sweet. so, peeps- what do you want me to do with this ******* problem? well help me. the other thing is that I got some *very interesting files* & I DON'T WANT TO DELETE THEM. that's kinda all. so please help me.
