During shell swapping 2 N3DS', i accidentally damage the home key ribbon cable so I decided to send it to Nintendo to be repaired/replaced. Luckily I live close to Nintendo's office so I just took a bus and dropped it off since I still had warranty. Obviously, they managed to find out the 3ds has been previously opened and the lazy ass technicians refused to repair it. Luckily, i found a home button ribbon cable for $5 on aliexpress so i'll have to do it myself. Anyway, if any of you try to send an opened 3ds, they will know. Atleast I tried.
