I just gotten my 2DS Pokemon Green version. Too bad it is on fw 11 already so I went I got a hardmod to downgrade it. Then I thought why not pay and install an usb port to access hardmod later easier as I want to play with it later. But the one who did it said he couldn't get 2DS with installed USB port recognized with his card reader most of the time. Anyone have experience on this matter? The hardmod for downgrade work fine though. And where is the ideal place to make the usb port? I thought of the wrist strap holder place but don't know if it will do.
