i have an r4i gold 3ds the settings was working fine earlier but when i tried to change the skin and settings it took too long to save it was at 'loading' for awhile so i just turned the system off but when i turned it back on the settings was gone and the bottom screen just shows black and the top is white. the settings is missing and the start button doesn't do anything. but games work just fine on it. did i just break it or something? what can i do to get the settings back?
