Firmware 9.4.0-10U does not give pcdata bin file

[JMan1122]

I just bought a preowned 3ds with a firmware of 4.5. I needed to get it up between 9.0 and 9.5 and the closest I've managed to do so is to buy some game called "Code Name Steam". It then updated it to 9.4 but when I tried to use the pcout link, (I've made sure I typed them in correctly) the exploits runs and crashes but when I put the SD card into my computer, no pcdata bin file. (I also have both pcin and pcout bin files on the SD card as well) I also tried to use QR codes but still no luck. Is there something I'm doing wrong? I can't update through wifi because we all know it's going to update it to 9.5.23 which basically makes it useless. Can anyone help?
