Hello guys, i am the owner of a New 3DS with the System-Nand firmware 9.0.0-20E. Sadly the blue card of gateway don't work on the System-Nand anymore and i tried to install the bluecardfix.cia. I booted gateway with the ocarina exploit, booted gateway in System-Nand and installed the .cia file over dev menu. But when i insert the blue card on System-Nand the card still don't work. It makes me crazy, since i tried it now with many tutorials but like always it don't work. I hope someone can give me a solution ;( Thanks in advance!
