Tried unsuccessfully to update firmware on my genuine (very carefully sourced) R4i 3DS bought years ago, to allow my kid to use on 2DS (updated to 11). Looks identical to ones still being sold (tried every firmware I can find) but hardware must have changed, cart still works on DSi. Gonna have to buy another, but cannot find any sites that are secure selling them, prefer UK site but will import from China, simply not prepared to use unsecured options for payment, surely nobody is daft enough to put their bank login details into a spurious site? Anyone got suggestions. Secure certificates are essential.
