I have an R4I SDHC 3DS WI-FI (No RTS). I am trying to use it on the latest 3DS firmware version ( 8.1.0-19U), but everytime I try to boot it up, I get "An Error has Occured. Please turn off the system". I'm using the latest firmware from the website, http://www.r4i-sdhc.com/. Can anyone help me? (I do not have anything but my 3DS).
