Okay then, for example, Bravely Default. The game is queued, goes through the entire download process, then gives that error. I was saying that those 2 were of the 6 games that actually worked, the rest do not. I'm having trouble finding exactly what that error code means, so I thought I'd ask here....
Yes, but "Here are some games that work, others don't" isn't helpful. Maybe you were trying to download SNES VC on an o3ds? Maybe you were trying to install Xenoblade or some other N3DS exclusive, we don't know, because you didn't tell anyone what was failing. That's the funny part, everyone, not just you, posts what works, but rarely if ever posts what doesn't. And the gets defensive when it's pointed out that the useful information isn't what works, but what doesn't.
Is your internet connection stable? As
@Billy Acuña said, an unstable internet connection can cause some issues.
Do you have enough free space on your SD card? There's currently no checks in place to make sure space is available.
Have you ever (Even if you've formatted since then) installed these games on your 3ds? FreeShop should remove the existing ticket, but maybe it's causing an issue for some reason.
Based on the error number given, these are the details:
Level: 0x1F (RL_FATAL)
Summary: 11 (RS_INTERNAL)
Module: 32 (RM_AM)
Description: 34 (UNKNOWN)
Even FBI doesn't seem to list what description 34 for the AM module is.
