I did a system transfer for the DSiware save exploit: https://3ds-guide.b4k.co/installing-boot9strap-(dsiware-save-injection) Source: Old 3DS XL Target: New 2DS XL I followed all steps successfully and picked picked PC-Based Transfer as the method. After transfer the source 3DS said transfer was successful. Target finished the transfer then tried to connect to the router again and I got error code 028-3136. What went wrong? The target was not connected to my NNID after the transfer. It also did not download any save files. On the source system there is a new folder in exdata called "Nintendo DSiWare" with a .bin file called "4B513945". It's not on the target system. Can anyone explain to me what went wrong? And can someone also tell me why Plailect didn't include any troubleshooting for this error in the guide? Was this due to using the PC transfer method as the guide suggested? The game I used for injection was Four Swords, if that matters at all. The exploit was successfully added to the game but it did not transfer to the target 3DS.
