how about the browser? have you changed it using .cia from 3DSNUS?
My emunand is 9.4.0-10E and i use this tutorial:
1 – Don’t panic!
2 – Go here:
https://gbatemp.net/threads/3dnus.376488/ and download “3dnus”!
3 – Unzip the archive using your favorite program.
4 – Open the folder that you unzipped the program.
5 – Open either “3DNUS_64bit.exe” or “3DNUS_32bit.exe” in your computer.
6 – In the program, below “Title ID” type(without quotes): “0004003000009D02”
7 - Below “version” type(without quotes): “4096”
8 – Check the box that next to it says: “Change version number(s) to:” and type in the box next to it (without quotes): “65535”
9 – Make sure the box that says: “Pack as .CIA” is checked, and press download.
10 – Wait for it to download! (It will tell you when it is done!)
11– In the same folder that 3dnus is, will appear a new file named: “0004003000009D02.cia”
12 – Copy “0004003000009D02.cia” to your SD card.
13 – Place your SD card in your 3ds and install “0004003000009D02.cia”
14 – Congratulations! You installed a exploitable version of the browser and you are now ready to go!
15 – Pat yourself in the back and go to the next Spoiler tag.
