Réponse rapide du constructeur :
Please use another console of lower version to update your R4i 3DS card, and download the latest firmware v1.58b from http://www.r4i-gold.eu/downloade.asp. If it still has problem by doing this, please kindly wait until we release a new firmware in the near future. Only few part of R4i cards those are not compatible to FW V1.58b.
Donc si j'ai bien compris, il faut attendre une nouvelle version du firmware.....
