I bought the r4i pictured above about 6 months ago and it was ok but when my 3DS needed updating I decided I would update the 3DS and update the firmware on the r4i with my DS phat or my sisters DS lite. For some reason it won't let me update the firmware even though I copied all the files from the latest update. What I have tried doing is copying all the files from the compressed folder and saying to copy and replace but when I go onto my DS phat or my sisters DS lite I click on config then upgrade but it says what the current version supports but doesn't give the option to upgrade. It used to upgrade on my DSi but that broke so I cant use it any more. Does anyone know how I can upgrade the firmware on my r4i so it will work on my 3DS.
