I asked this in the 3ds noob thread already but didn't get a concrete answer so I'll ask here again. I decided to change my console's region from JP to EUR using this guide: https://github.com/Plailect/Guide/wiki/Region-Changing As it wasn't stated in the guide, I did not think my data would be missing after completing it so I didn't perform any special back-ups other than the one stated in the guide (NAND backup). After I switched to EUR region, all my previously installed CIAs were gone, but for some reason, they still show under the Software tab in the 3DS menu. They are marked with a blue cross though. I tried running CacheTool as suggested in the 3ds noob question thread but to no avail. My micro SD card still has all the files that were there before I performed the region change. Has anyone got a solution? If not, will installing the NAND back up bring all my files back? If yes, will I be able to back the installed cias up in some way to restore them when I go for the region change for again?
