According to the R4i-SDHC RTS offficial website, R4i-SDHC RTS cards can support N3DS V6.1.0-X perfectly(certain model only),you can update your kernel to v1.71b. If your RTS cards cannot support firmware update for the moment, please be patient, upgrade firmware will be released soon.Now many store have provided the lastest card,you can buy it from http://www.modchipwarehouse.com/r4i-sdh...s-lite-p-3.html
but i just test my 2 r4i 3ds cards. one is r4i sdhc3ds v4.5 and another is r4i sdhc 3ds rts, both cannot be updated.
the official said if the card cannot be updated, need wait another firmware..
Despite the R4i-SDHC RTS 1.71b update, which all say works perfectly with the Nintendo 3DS 6.1.0.11U which is my model, I keep getting the 'an error has occured...' message every time I try and load my r4i 3DS RTS card... This is very annoying... any help?
