So,i got a r4 gold pro from http://www.r4isdhc.com/,formated the micro sd card with the program in the http://www.r4isdhc.com/r4-fa/, downloaded and extracted the kernel files to the root sd,inserted the sd in the r4,the r4 in the 3ds and started the app. But it didn't work,black screen. Not a error mensage,nor a white screen,just black, nothing more I tried to format in other ways,tried other kernel files but nothing. Can someone help me? (My bad the poor english.) 3ds ver: 11.4.0-37U Not original 3ds xl,arm9loader,something like that.
