Default Sudden Pokemon Data Corruption

First off, I'd just like to say that the data corruption didn't occur in Luminose City and it wasn't because I was saving. Second, the data corruption occurred approximately 20 minutes after I installed the patch update version 1.1. I also need to mention that I bought a digital copy of Pokemon X. I don't have the game cartridge.

I was on Route 12 trying to catch Mantyke, but pressed the "Home" button after I used way too many pokeball and Mantyke ended up fainting away. This I've done lots of time already without a hitch. And this is where I think the problem lies. I updated the patch so the game was 1.1, but I didn't save the game when I was playing (I think?). When I started the game up again, this message showed up "Saved Data Corrupted" and on the bottom of the message was "ver 1.1".

Luckily for me, before the patch update, I was transferring the info from my 2GB SD card to the 16GB SD so I have the entire game and information saved on my laptop just 30 minutes before. The transfer went fine and I was able to play Pokemon no problem like I said for 20 minutes or so.

Thinking it was an ease fix, I wiped the entire data from the SD card and replaced it with the saved data I had on my laptop. When I popped it back into the 3DS, everything worked fine...except Pokemon X. When I start it, it now says, "Saved data is not compatible with this version". I'm thinking it's because I did the patch which updated the game to 1.1, but the old data I had in my laptop was still 1.0.

So I hard reset the 3DS, reformatted my SD card, and redownloaded everything. So now my question is...is there anyway to save my .sav data for Pokemon X? As in, is there still a chance I can transfer all my old data back to the SD card and have the 3DS read it? According to the Nintendo Support FAQ, if it's just transferring information from one SD card to another with for the same 3ds, it should work like a charm and for a while it did. I was able to play Pokemon on the new 16GB card no problem for 20 minutes...and then it crashed.

Did I just screw myself over when I did the hard reset? But I tried everything before I even resorted to that. I wiped the newer 16GB game and redid the steps again, still no go. Version still incompatible. I even went back and tried to use the old 2GB (that I didn't tamper with), and Pokemon still didn't work even though the crash didn't happen with the 2GB SD card (version still incompatible). I deleted every thing in the Data Management that was related to Pokemon and that was when I finally did the hard reset.

I've tried looking around, but no one seems to have the same problem I do where I actually do have my data saved prior to when everything went down hill. I've read somewhere that Pokemon X/Y its folder has the .sav data from the SD Card, but I forgot what the user said the numerical number for the folder that contained it. I was hoping that I could just copy and paste that specific file.

I also know that some people also encountered the dreaded "incompatible" message when they tried to create more than one save file, but I'm not sure if that is really my problem? I'm not sure how it works. I just want one, which is my old save file. If I can, I want to overwrite the new one with my old one.

7 hours in, cleaning, copy-pasting, redownloading, and searching all over the net for a concrete answer, I finally resorted to asking for tech help. Sorry if it's a long post, but I wanted to make sure I didn't leave anything out in case someone can help me. I'm seriously at the end of my ropes here...

EDIT: Perhaps I should also mention, because of the hard reset. whenever I insert the SD card, it always wants to reformat it and I know for the games and download content to work perfectly, I shouldn't let the 3DS format it with previous 3DS content already on the SD card.

EDIT 2: I should also mention before I did the hard reset, I tried System Repair via eShop. I ended up redownloading the game (which is about 3 hours). Afterward, when I tried to open the game after the redownloading, yup you guessed it, "Version Incompatible". It was only after a hard reset, downloading the game again, did I even get past the error message that pops up immediately the moment I start the game. But everything was wiped, I lost my data. Everything. I don't understand what went wrong. All I did was press the Home button! How the hell does that corrupt a game?!?!

Unfortunately Pok?mon uses the same save system that Animal Crossing does, and your efforts to back it up are what have caused this problem.

Every time the game is played new checksums are generated in system storage, which are tied to a specific save. When you wiped your data and restored the old backup these checksums no longer matched the save, and so the save file will no longer load.

I'm really sorry that this happened to you, but you have no choice but to start again.

Next time you perform a backup it's important that you do not play Pok?mon (or Animal Crossing) again before restoring it, otherwise you'll lose everything all over again.

Then can you tell me what I should've done instead? I simply don't understand what went wrong in the first place. The checksum issue should've only happened after I wiped the data, but it occurred before that even happened. Wiping my data was my second to last resort. I went to the home menu, opened the game again over and over to only see the message; went back to the original SD card, and then I wiped. Prior to the wipe it was "Saved Data Corrupted" and after the wipe it was "Version Incompatible". I'm just super frustrated this happen when I don't understand what even occurred. Is it really because I didn't save before I pressed home after the patch????

EDIT: Perhaps I should mention that I did not immediately play pokemon after I transferred to the new SD. I went to eShop and downloaded the patch first.

With no way to verify exactly what you did, I notice you're unsure yourself about whether you saved or not, I can't give you a concrete answer about exactly what happened.

Data corruption is rare but it does occur, it can be caused by anything from prematurely resetting or powering off your system to a bad SD Card.

What I can tell you for sure is that no matter what you do now, there are currently no tools which can help you restore that save.
