Nintendo 2DS kartdlphax problem

[LedLantern]

Hello, I was trying to homebrew a nintendo 2ds for a friend using the kartdlphax method. But when I start the local multiplayer session in Mario Kart 7 on the already modified nintendo and the sending hax process ends, on the unmodified nintendo it opens the xPloit injector for a second and then it gives me this error.
I tried using a different SD for the unmodified nintendo but it didn't work. I was thinking that, since I already used this method previously with my 2ds, maybe it doesn't work anymore?

The device on the picture is already modded.
That is a Luma3DS crash screen.

Clarify: Does the crash happen on your modded console or on the 2DS you want to mod? If the latter, you don't have to use exploits at all and should rather start here:
