I have been having an issue on my nintnedo 3ds XL for several weeks now where several of my games have updates but I always get an error code directly before the updates are completely finished. I have tried starting the updates via the "press Y to update option at the game launch," downloading the updates via sleep mode, and directly from the nintendo e-shop, all of which start, download, and fail around the 99-100% mark of completion. I then tried downloading a couple demos from the nintendo e-shop to see if they downloaded and they failed as well. I figured that this was a nintendo e-shop error as I had no trouble downloading the 3ds update a couple days ago, or download several free in-game dlcs in Monster Hunter 4 Ultimate. I am also able to play online on MH4U, and download other thing on other various devices, so I know its not my internet connection.
I have searched the error codes on nintendo's support forums and there is no information on either of the error codes I got. I've attempted several suggestions in the troubleshooting FAQs such as reseting my internet connection in the connection settings, to no avail. I have listed the games I have tried, the games I'm trying to update, and their error codes below.
