I installed the exploit with the Blue card, no problems. Then I tried to trigger the exploit with the Yellow card by clicking on the profile like I saw it in all those tutorial videos and like I read in the HowTo's.... no dice. It just produces an error. "An error ocurred, the system will now shut down..." I tried it with a Fat32 and exFat formatted microsd, all files in the root of the card. My question: did I do something wrong, or did someone sell me a broken MT Card? I'm on a 3DSXL with 4.4 firmware.
