ROM Hack [QUESTION] System transfer

[bastiqui]

Hello, first of all happy holidays to everyone

I have a 2DS with A9LH. The SysNAND is on version 10.7 and it doesn't have an NNID associated. Actually I have 2 SD cards:

In the 1st SD: I have an unlinked EmuNAND with my NNID associated, all my games, friends , homebrew, etc.

In the 2nd SD: I have another unlinked EmuNAND, it’s a backup of the SysNAND, so it doesn’t have a NNID associated. Then I upgraded the EmuNAND to the 11.0 version.

My friend has a N3DS(XL) that came with 11.0 and we want to downgrade it. The plan is to do a system transfer from the EmuNAND on the 2nd SD card, (that it doesn’t have a NNID associated) so “it will not transfer my NNID”.

If I execute the transfer from the 2nd SD EmuNAND, will also transfer the NNID that is associated in the 1st SD card’s EmuNAND?

If someone could help me, I would appreciate it

No, i dont think so, but is the 2nd emunand a backup of the 1st emunand?

ok, dumb question:
have you check the 3ds guide to hacking 3ds @
https://3ds.guide/get-started-(new-3ds)
and then
https://3ds.guide/nfirm-downgrade <--this is most likely where you will end up at...

No, the 2nd emunand it's a backup of the sysnand which never had a nnid linked before, but I have formatted it just to unlink it from the sysnand.

Yes I've checked the guide but there isn't any thread/FAQ about this specific scenario.

srry, the reason i mention the guide was this part:

If you are are between versions 11.0.0 and 11.2.0, you MUST have downgraded your NFIRM to successfully complete this part.

We are following the guide, step by step. But my fear is, if I do the transfer using the 2n SD CARD, will I transfer my NNID which is associated only to the 1r SD CARD? Remember I have two differents EMUNAND's...

ok, well, the emunand that your transferring doesnt have the nnid, as you have said:

In the 2nd SD: I have another unlinked EmuNAND, it’s a backup of the SysNAND, so it doesn’t have a NNID associated. Then I upgraded the EmuNAND to the 11.0 version.

therefore, i dont think it will carry over based on the fact that its the emunand, not your sysnand that being transferred over.

I'm not 100% sure how this works because I stopped using emuNAND long ago, but I do know that you can have more than 1 NNID tied to a console, but only 1 linked at a time. Easy way to test: load up the emunand without the NNID and try to make a new NNID. If it works, perfect, proceed as normal. If not, it means the system is still linked to your NNID on the other card. If that is the case you need to unlink the NNID first or it will transfer. You should be able to re-link your old NNID after.

Thanks for the answers, we gonna try to create a new NNID in the 2n SD CARD and see if it works.
But until next week we can't test it because my friend will not be here... I gonna try to update this thread if we get something doing it by this way.

Yes, it will, as confirmed by many people on this forum in the past.
