Hacking Create new NNID for DSiWare downgrade?

[tom2199]

In a few days I was planning to do a DSiWare downgrade for the first time.

My idea was to unlink my current NNID from my 3DS without formatting (see here), then create an Emunand, make a new NNID, buy a DSi game, make all the stuff that is required and transfer the new NNID to the other system. When everything is completed, I want to delete the Emunand and log into my old NNID. Would that be possible? If not, is there an other way?

I don't want to use my original NNID (I know I could transfer back the NNID after a week) because then I would have the unused money (used to buy the DSi game) on my NNID, not on the NNID on the other 3DS. I don't want to give my NNID away and make a new one for myself either.

When you say "unlinking" that just lets you make a new NNID or system transfer onto it. It doesn't unlink the NNID from the console on Nintendo's servers. When you do a system transfer, every NNID belonging to the source console will be transferred, whether active or not. If you want the source console's NNID back on the source afterwards you'll have to do a second system transfer or call Nintendo.

so it isn't possible to use a dummy account for buying a DSi game, then transfer it to the other 3ds and then log in to my old nnid on my system?

Nope, sorry!!
You can always do a system transfer back though, or call Nintendo. If the latter, you won't lose data if you restore your pre-transfer backup first.

Thank you, that's unfortunate. Are you saying that if I transfer my main account back and then use a NAND-Backup (taken before the first transfer), I would loose my data anyway? Or is that method possible (without calling ninty).

If you transfer your main account back your data will be transferred too, so you don't have to worry in that case. It's only if you call Nintendo that you have to be worried about your data, because only the NNID not the data is transferred. But in this case, if you restore the backup first then all your data is present, and the missing link is only your NNID which you solve by getting Nintendo to transfer it.

Just keep a NAND/SD card backup of your data on the source console. After transferring for DSiWarehax, you need to wait the 7 days and transfer back. Once the transfer is complete, restore your NAND and you should be fine. You can, of course, restore the NAND while waiting for the transfer cooldown, but your NNID won't work until you transfer back. There's no way around it because system transfers move all NNIDs that are associated with the source console to the destination console.

That also means that any NNIDs on the downgraded console would be moved to the original console when you transfer back, so if there is an NNID on that console that needs to be preserved, you'd have to call Nintendo at some point to unlink one of them.

Ah okay, thanks, that explains a lot. so there is no benefit if i would unlink my nnid from my 3ds first (through formatting it) to create a dummy nnid because both of them would be transferred to the other 3ds right?

Yeah, that's correct.

If you do a system transfer back you don't have to restore the NAND backup. Unless you formatted the target system and wiped the data.

i thought only legit games would be transferred? if so, i would need to do a nand restore to have my other games back, or am I missing something?

Oh that's true. Fair enough. If you have a lot of pirated games then a NAND restore + restoring the SD card data should bring them back. I haven't played a pirated game in a few months so I had forgotten about that haha.
