So I'm betting you can guess what happened. I've got a R4i 3ds cart and I updated the 3ds to version 4.3.0-10E before I updated the R4i firmware. Would anybody be willing to update the firm ware in a working 3ds for me. Willing to pay post there and back?
which R4i 3DS card do you have, what is the official site,is it this card http://www.dsflashcart.com/r4i-gold-3ds-wood-r4i-3ds-flashcard-for-ds-dsi-3ds-p-248.html i hope i can help you about it. and where do you live, if you live in USA, i guess i can help you about it. PM me.
