i have a wifi R4(i)card v1.4 i try upgrading it but it won't work is their a way i can set it back to v1.4 yes i try googling it and found nothing on how to set it back thank you Santi
just put the original files you had on it before you tried to upgrade. You should have backed it up? if not you will have to go to the site on your card and get the files again
Here is r4i sdhc official site download page: http://r4i-sdhc.com/downloade.asp there are three different r4i sdhc cards, r4i sdhc (with 1.4.2 or 1.43 mark ) R4i sdhc (without i mark) r4i sdhc 3ds After you find your card, just download the correct firmware.
