I did get Powersaves for both fixing this and Homebrew access, always handy in case anything else ever goes wrong I figured, and as it turns out... It was the right thing to do because it worked! I had to use a somewhat different method to fix my save than you suggested, as svdt alone didn't work (dunno why-but having automatic secure value rewriting enabled didn't do the trick), but disabling svdt's automatic secure value rewriting when decrypting the save and then using suloku's tool did! In case anyone else finds themselves in the same spot, here's what I did: To make sure what I did would work and for curiosity's sake, I compared the old file and the updated one in HxD, and voilà! There it was, address 0x75E00 properly updated. Thanks to the help and the tools (thanks Suloku!), I saved the majority of my Living Dex progress, my breeder Ditto, and my complete Vivillon collection! :kikkoman: Again, big thanks for the help!

Thanks for the detailed response! So in theory, since the system transfer was successful that might mean I can decrypt-since the decryption key could be on the N3DS now. That seems to corroborate with what I read on the thread for Suloku's tool on GBAtemp: https://gbatemp.net/threads/antisavegame-restore-secure-value-updater-ps-acnl-prw-ssb-xy-oras.396644/page-5#post-6162100 I actually misread that postchain initially, so I was under the impression that only the savefile's original system would able to decrypt, hence the dumb question earlier. After re-reading the linked post and yours, I realize that should only be true should the system transfer fails for some reason. Since mine didn't, that's at least one spark of hope for fixing the save. It's settled then, when postal services delivers my Powersaves I know what I'm going to do. Big thanks for the help so far. I'll update on how it goes once I've had a chance to try homebrew out.

Because the secure value is kept on the console itself? Hmm...since I don't have any homebrew running atm (but I should be able to install it) does that mean it's impossible? As in, if I were to install Homebrew now (thus gaining access to decrypting) on the O3DS, I wouldn't be able to decrypt the save anyway? Or, does that mean that in order to decrypt the save I have to first system transfer back to the O3DS (so the save is on the matching console)? Then install homebrew (thus gaining access to decrypting the savefile) on that console? Sorry if it's a really dumb question, just making sure I get the hang of things.

Hello fellow Project Pokémoners, I've come here in the hopes of finding help on fixing my AS save. In short I've found myself in a situation where my e-shop AS save is "corrupted" after a system transfer from a stock O3DS to a stock N3DS. Here's the breakdown of what happened: So, my AS save is now "corrupt" because its secure value doesn't match up to the N3DS's secure value. And now I'm here because I'm a bit lost as to how I can fix my save, I think I get the gist of it, but I have some blanks to fill in. To fix this I need to update the old savefile's secure value to match that of my N3DSXL, and to do that I need to have a way to decrypt my savefiles. Which means installing homebrew and then using either svdt/savedatafiler/suloku's anti-savegame patcher/manual Hex editing? In terms of Homebrew options here's what I have: My O3DSXL that I transferred from (source). No homebrew installed. Ver. 10.7.0-32E My N3DSXL that I transferred to (target). Again no homebrew. Also Ver 10.7.0-32E The SD card from the O3DSXL with everything intact (including the old (encrypted) AS save). So, I should be able to run OOTHax (via Powersaves+OOT retail cart) and then install a9lh. But being the noob that I am, I'm a bit confused about some things (and thus I have some dumb questions): Do I need to homebrew both of my consoles? If so, in what order? (E.g. do I start with getting the secure value off the O3DS or the N3DS?) Since it's the same NNID on both consoles, does that mean that only one console can be homebrewed at a time? Once homebrewed, can a console be restored to stock and still use the fixed save? Many thanks in advance.
