Yesterday I unpacked my old 3DS with firmware 4.3.0-10E. Today I got Cooking Mama: Bon Appétit, and used it to update my 3DS to 9.2. So far so good. Next I wanted to use a browser exploit to get into the eShop and buy Azure Striker Gunvolt before the Mighty Gunvolt promotion ends. However, despite trying repeatedly, it didn't work. After some reading I figured out that I needed to update my web browser to version 20. Okay, I had a bookmark to a post that explained how. Used 3DNUS to download the files, packed as a CIA. Placed the CIA and FBI on my SD card. Next I launched Cubic Ninja and launched the Ninjhax exploit. But no matter how many times I try, it remains stuck at 70%. I tried other QR codes as well, but it just isn't working. The FAQ suggests that I'm using a wrong QR code, but I double-checked it and I am using the correct one. Other users with the same problem suggested a different SD card. So I tried another one, but the problem persists. The only other option is to mail smea, which I did. But others who had the same problem never got an answer. HELP!
