Well, it turns out that I made my sysNAND backup using a version of rxTools that I later found out was making unreliable NAND backups that could potentially even cause bricks. As I do not have a hardmod and don't feel very confident about the pinouts shown in the only thread I've found so far (nor feel horribly confident about actually DOING a hardmod) I must consider that backup to be worthless and have already deleted it and created a newer backup with emuNAND9 instead. Anyway, at this point MenuHax, BrowserHax, and NinjaHax (I have Cubic Ninja) makes it completely unnecessary for me to use the DS profile exploit anymore. Heck, even if I need launcher.dat exploits for whatever reason I might as well use the old browser exploit (as it is a 2DS I can't safely downgrade the entire system to 4.x, so the old 4.x launcher.dat exploits won't work here as offsets are different.) Undesirable I would say in fact as it's a lot more trouble, slower to actually do, and I'd swear it's even less reliable. Now, I don't strictly need the original mset on there right this minute, but it worries me that if things should ever go wrong and I have to do a system format or something it could potentially cause troubles. As there is just no need at all for a downgraded mset anymore I want to just go ahead and restore it to normal. I don't want to do anything messy like updating the whole sysNAND to 10.3 and then redowngrading or something though. I did the downgrade using rxTools, but if it even has an option to restore the mset that option disappeared for me somewhere along the way and at some point I had to delete the rxtools folder and start over as something was just plain messed up (black screen every time until I started over.) Now, I have the 9.2.0-20U(Full) system files package available. If I'm reading correctly the correct file I want is 0004001000021000.cia (and certainly that file is missing from the one that says "no.mset-twl-wlist-agb" which at least makes it 33% more likely that I've correctly understood which title I'm looking for.) I tried using sysUpdater, but whether I select downgrade or even upgrade, it just acts like everything goes well but doesn't show any CIAs being installed at all (no failed, but no success either. It's just the one CIA file in that /updates folder.) I was kind of tempted to try FBI, but it won't overwrite an existing title. I'm kind of wondering if I can use FBI to delete the existing title then install that, but I'm really not sure how to tell which it is since it's just listing a bunch of stuff with the same exact names and I'm not sure how safe this is besides.
