Hi, I have an issue with my modded 3DS. I followed the guide and everything worked fine until I switched from a 16GB SD card to a 32GB one. After that, everything started going wrong — I had issues with games, Luma, Homebrew, etc.
I had to switch to a regional NAND because of these problems, which I tried to fix on my own. I managed to repair almost everything except for one game: Miitopia, which never launches and gives an ARM11 undefined instruction error.
My other issue is that I can’t install any games or software through Universal Updater anymore.
Thanks in advance if anyone can help😅

What do you mean by switch to a regional nand
Also send a picture of the error miitopia gives you
And what happens when you try to download from universal updater? Does it say it failed or succeeded?
Régional nand ^^
Root of sd card ^^
For the regional NAND, I followed what someone told me, and it semi-bricked my console. My original NAND was impossible to recover. After some research, I saw that I could inject a regional NAND, so that’s what I did. After that, I was finally able to turn my console back on, but it was bricked because of the advice from this person who originally wanted to help me fix the problem with the games that couldn’t be seen or read. The error I had before is now the same one I’m currently getting with Miitopia.
I still dont know what you mean by region nand. Was it a region change or a ctrtransfer?
Link the guide you used
Also what do you mean by semi bricked
It was a CTR transfer
A complete guide to 3DS custom firmware
Basically, the console wouldn’t boot anymore, so I looked for a way to fix it since the NAND was no longer functional. I came across what some people call a regional NAND, which can be used to replace or repair a damaged NAND. After that, the console was able to start again.
As for guides, I searched through all the Reddits, videos, and websites that could help me before coming to you, but I couldn’t find any solution to fix my problem. I tried formatting my SD card to FAT32 and even reinstalling Luma, but nothing worked — I still can’t resolve the persistent issues.

Send a picture of your sd card
Root of sd card ^^
The physical sd card
You need a new sd card
Why 😅
Sandisk, lexar, kingston or samsung
Your sd card is likely whats causing your games to corrupt
The errors you got mean theyre corrupted
Transfer your data to a new sd card then delete and redump/reinstall any corrupted apps

About SD-Cards
For general information, please check [the FAQ](#1270692745056485417 message)
The 3DS family can take cards up to 2TB. However this is not recommended as you will run into issues with cards larger than 128GB.
Cards above 32GB will have to be specially formatted. Consult ?formatting for more information.
Buy SD cards from reputable brands(SanDisk, Samsung, Kingston, etc...). Never buy used cards or cards from questionable sources like AliExpress or Wish.
Card speed is irrelevant for the 3DS as it is limited to 4MB/s (Class 4). Faster speeds will only benefit you when transferring files from your PC to the card.
Yes, I had read that on Discord. I’m going to try changing my SD card. Thanks for your input — I’ll see if changing it fixes the issues.
