So first off .. I bought my N3DS used, with Gateway already installed. Whoever modded it clearly didn't do it right, because they're linked. I want to update my emuNAND to play Pokemon, but I can't obviously. Problem is, I don't know anything about modding itself. From what I've gathered I need to: Remove internal SD card, format sysNAND, re-insert SD card = emu and sysNAND unliked. Cool. Except .. If I do that, won't I lose the DS Profile exploit? Since I got my N3DS used I don't have the means to re-hack my console with the DS Exploit so I have no idea how I would access Gateway after formatting sysNAND ... Any noob-friendly help with this? Second problem I have relates to installing custom DLC files while on emuNAND? I had this problem with Fire Emblem Fates on my N3DS, and literally the only way I could get DLC on the game was to use FBI's QR Code download/install thing. That's fine and all, except that only works for -official- DLC. I just tried to install Fates Restoration Undub DLC for my friend's console, and he has the same problem I do: Any DLC we try to install results in: Invalid cia file. WTF?! I've tried with FBI, Title Manager and DevMenu and the problem persists across all of them. I've tried to google so much on this yet I can't find anything at all .. Any help with both problems would be greatly appreciated.
