My ds was working fine, but suddenly it wouldn't charge or turn on. I just thought that my ds's battery was dead, because the same charger would work on my other ds. So, in my infinite wisdom, i took out my CF supercard and put it in my other ds, with a passme. Now this ds is showing the same symptoms. I have a fairly old version of flashme on one ds, but using A+B+Select+Start didn't do anything, any ideas?
