Hi. I have this problem for a few days now: i had a theme on my 3ds and i wanted to change it but when i downloaded another theme and turned off the 3ds, when i turned it back on it goes to default (white) but if i press the power button and then the home button the theme shows up again and if i turn my 3ds off and then back on it goes back to white.so now when i turn on the 3ds the theme is always the default (i tried using other themes and a colour from the settings).any ideas on how i can fix it?
