i have a dsi with fw 1.3u after browsing the web using wifi, my r4 stopped working. it just shows a black screen error message just like the 1.4u error. i tried it on another 1.3u dsi and the r4i works! is there a fix other than buying another r4i with the 1.4 logo? by the way my r4i is just this: http://r4i-sdhc.com/indexe.asp but there is no 1.4 sticker.
