Hi! I changed the slot card reader of my DSi (the other was defect) but my DSi don't see the cartidge. Maybe I made a mistake... When I unsolder the defect slot card reader, I unsolder the 2 small pins in the bottom right-hand. But the copper hum.. "it went out", "it left". Sorry for my englisch...Do you understand me ^^ ? So I can't solder these 2 pins... Are they important ? Where I have to solder them ? Thank you!
