Deleted backup.bak, replaced with a copy of "main" renamed as "backup", and transfered save to ofw. Looks like the problem is fixed, at least as far as I can tell. Thank you so much!

It works with a fresh save, yes. Both the transferring Pokemon into Home without it remaining in Sword and the transferring Pokemon from Home into Sword without deleting the Pokemon.

It looked like there was a backup.bak in there... Deleted the save in ofw, launched Home, and there's only the option to use Home without connecting to a game. Sword did not show up as an option.

Yup. poke_trade was missing. Added it back in, and shifted the save from cfw to ofw. Thought maybe that would fix it but...still the same problem. In fact, it's back to how it originally was when the issues started. At some point, in the process of trying to fix it, I was able to transfer Pokemon from Sword to Home with no issues, but now when I transfer a Pokemon in, save changes, and then boot Sword up, the Pokemon is both still in Sword and also in Home.

The copy of the save I originally backed up and edited in PKHex then reinjected into the emunand was labeled "main". I used the video I linked above as a guide on how to get it to ofw without exposing my sysnand to cfw. That method had me copy the save data using Tinfoil, from the file browser: user:/save/0000000000000023 and user:/saveMeta/00000001.meta. I don't exactly remember, but I seem to recall maybe having some kind of issue with injecting the save with EdiZon? Like, it having no effect, so I tried again with the PKHex backup file, main.bak? I don't remember which one I got working, in the end.

I get a white screen with "There is no backup data, so you can't load data. You'll be returned to the title screen." written on it.

Ok.

1. went into options, deleted the save file from data management 2. No, since there's no save data on the eumnand, the game doesn't show up in Checkpoint at all 3. yes 4. can't load Sword in cfw. "Some necessary data could not be found. It will be downloaded now." (I downloaded everything I could from Tinfoil so idk what else there is.)

deleted my saves for both Home and Sword on the emummc side, powered off and rebooted into sysnand, and tested it out. Pokemon Home transfers to Sword still don't save. I don't know how to unsync my profile so idk if that's the issue? Can you link me to a better place to ask for help with this issue?

I tried that at first, but the save data didn't transfer over to Sword when I booted it up on sysnand, so I used this tutorial: Now the save is on sysnand, along with Home. I guess Home is technically on emunand too but I'm pretty sure to get it to work there I'd have to shut down incognito and 90dns and I'd immediately get myself banned. Does the Sword save data being different on emunand and sysnand affect anything?

I am. Why do you ask?

After modifying some of my boxes in PKHex to have the (100% legal) Pokemon I wanted, and injecting the save back into Sword, I noticed that when I transfer a Pokemon to Pokemon Home, then boot my copy of Sword back up, that Pokemon is present in the box slot, but it's also still in Home. When I transfer a Pokemon from Home to Sword, the Pokemon is gone from Home, but isn't present in Sword either. (I haven't lost anything too valuable thankfully, but I assume the few Pokemon I did transfer are gone forever.) When I move a Pokemon from one box slot to another in Sword via Home, the changes are not saved either - the Pokemon is present in its original slot and absent from the slot I moved it to. Any idea what's going on here? If it helps, I injected the save by ripping it with EdiZon, editing it in PKHex, restoring it with Checkpoint (I was having issues with EdiZon at that point), locating and backing up the save files with Tinfoil, mounting my Switch's sysnand, and replacing the previous save files with the new ones. It seems to have worked in that I'm not banned, but the interaction with Home has me quite worried. Seems like Home can't save changes to Sword for some reason? Also, saving in Sword and reloading does keep the saved changes. It's only saving Sword from within Home that isn't working.
