Ok, so I got an R4i flash card from [censored] which lists the website to get the needed firmware as r4i.cn so I went and got the firmware extracted it onto the microSD card and put it in the DS and when booting it just loads the main DS screen which says there is no card inserted. I don't know what all information you might need but let me know and I'll get it for you. Just really stuck here and would like to get this working for my son.
