Is this possible? I'm trying to do a downgrade for a N3DSXL through DSiWare but I can't download anything from eshop. I get the 007-2404 error whenever I get to the preview page.
No, and you'll also need to be on the latest firmware to do the Dsiware downgrade. You either have to use custom firmware or arm9loaderhax.
I was under the impression you could do a N3DS downgrade if you already had a 3DS with CFW installed.
If your system on 9.2 has custom firmware, you can update your emunand to the latest firmware to do the downgrade.
Sorry when I said CFW, I meant arm9loaderhax on 9.2 So I can make an emunand, update that buy the games needed then downgrade the N3DS is what you're saying? Sorry for the confusion.
If you have arm9loaderhax, you can update your system to 11.0 and you don't have to make an emunand if you do that.
Wait, I can update to 11.0? That won't remove anything like installed cias will it? I was under the impression I'd lose the ability for homebrew, etc if I updated. I'm fairly new to this so excuse my ignorance.
Also, if you are using gateway cfw, DO NOT UPDATE IN GATEWAY MODE. You will lose your hax, and be stuck on 11.0. Update with luma3ds, or any other cfw would work.
