I'm trying to use the new SD card menu on the 4.0U update but get the error: "Failed to Launch" I've read that I need IOS60 to use this feature but cannot find a good explanation on if it's possible on a LU64 4.0U console. I'm pretty sure I'm using cIOS249 but have no idea on how to check if any other IOS's are installed. So I do not know if it's a matter of patching or installing IOS60. I've read that downgrading will brick a LU64. My system was a 3.4 but I updated to 4.0U using the official update from Nintendo. Thanks in advance for anyone that can shed light on this topic!
