Hi! I setup http://www.r4isdhc.com/download_white_new/ last frimware and it work good, but then i install last frimware from http://www.r4isdhc.com/download_silver_new2013/ and after this my r4 card on DSi XL shows "White screen", without any "Loading...", what i need to do? Can i reset frimware or anything else? or r4 card is dead? Thankyou!
