I bought my iTouchDS a month ago, and it was running smoothly. Then I started to play The Simpsons Game. One day the game froze and all the pixels became distorted. I turned it off and then back on. It displayed the Health and Safety screen, then stayed black forever. Sometimes, it tells me theres no boot.xxx file, even though my computer shows it there. Also, after putting it in my computer and back in my iTouchDS, it worked for about 2 minutes before freezing again. Please help!
