So I wanted to test something on my 3ds, which required formatting my system. Of course before doing that I made a NAND dump and a backup of the SD card, thinking I should be able to simply restore the dump and SD contents after testing to restore my previous system. Unfortunately I've hit a little problem. It seems the folder names the system uses within the Nintendo 3ds folder has changed, and restoring the NAND dump does not fix this issue. Before (when I created the backup): Nintendo 3DS\418b01df201350d7c0895fc6394a9419\5e1b01054221b3d74e44344700284245 After format and restore: Nintendo 3DS\418b01df201350d7c0895fc6394a9419\550300fb301000003030303000284245 I do have A9LH, a full nand dump and a full backup of the SD card when the dump was created. I just can't seem to figure out if/how I can get this fixed. Worst case I didn't play a whole lot on it anyway. And luckily I do also have save backups of the important games so I'm not totally screwed, I just don't want to have to go through reinstalling all of my titles.
