Darn, it would be a shame if you aren't successful so I'll try to share what happened in my experience......
I have already modified 3 3DS units, all of them successful
- Pink Classic 3DS (US) on Firmware 4.4U
- White Classic 3DS (JP) on Firmware 4.4J
- White Classic 3DS (JP) on Firmware 7.1J
I used this tutorial :
https://gbatemp.net/threads/tutoria...r-firmware-to-cfw-4-5-without-gateway.378371/
Here's what I remember on my second and third modification.....
- Before creating the emuNAND, I made sure that the 3DS is connecting to the Wi-Fi network AND the computer can connect to the 3DS. To verify this, I used the Network Scanner linked in the tutorial. When the 3DS is detected in the scanner, it says "Nintendo Co Ltd."
(As an addendum, when I used my normal router, my PC cannot detect the 3DS in the Wi-Fi network, what I did instead is create a hotspot from my Android phone and use that as the Wi-Fi connecting my 3DS and the PC.)
- Backed up the NAND.bin and then copied it to where emuNAND Dummy Creator / Tool is located.
- I set up emuNAND (The warnings about not finding NAND.bin did not happen in mine.) and the other stuff.
- Created the DBS folder and the 0-byte files "title.db" and "import.db"
- Now in the most annoying part, I enabled the WLAN switch in the 3DS before the "hold L Button after loading the DS Exploit and running the CFW". After the CFW loads, I immediately go to the Internet Browser. (If it crashes/hangs, tough luck, if not then that's darn lucky)
- I try to connect to any website. Since my Android hotspot isn't connected to the internet, it will do nothing, but the Wi-Fi status would change from "ENABLED" to "CONNECTED"
- After that happens, I use the Network Scanner again to verify that my PC can see (and connect) to the 3DS. If it gets detected, I copy the IP address seen in the Network Scanner and then edit the batch file.....
Example :
installcia 192.168.43.22 1 DevMenu_2x.cia
Hope this helps.
