Hacking NAND backup/restore question.

[DinohScene]

I couldn't find a good answer anywhere unfortunately ;/

Anyway.
I got a K9LH'xed O3DS with an active NNID.
If I where to make a full NAND backup + backup of the SD card and format the O3DS to temporarily use it to downgrade a N3DS on 11.2, could I (after it's all done) restore the NAND backup + SD card to the O3DS and boot it again without having to relink me NNID?

Basically, what I'm trying to achieve is have a "clean" K9LH'xed O3DS to perform a DSIware downgrade on a N3DS and then restore the 3DS to what it was.

When you system transfer, all the NNIDs associated with the console transfer as well. If you want to get your NNID back to the source you'll have to call Nintendo and ask them to move it.

Forgot to mention that I'll create a temporary NNID for the transfer.
After the transfer, I'm planning to restore the NAND backup (containing me own NNID) to the O3DS again.

Me bad ;p

All NNIDs associated with the console will move, regardless of signed in or not.

Fair enough.
Cheers for the response.

edit:
Any way to do this via EmuNAND?
Making sure there's only 1 NNID (the temporary one) associated to the EmuNAND?

No, this is all done server side. If you create EmuNAND and a new NNID, it will still transfer the old one since it is still the same console in Ninty servers, trust me I just did this 2 days ago.

Just create backup, do DSiWare downgrade, then you have two options:
1) Call Ninty and tell them you broke the other 3DS and would like your NNID back to this other one. Then restore NANd backup.
2) Wait a week and transfer back, then restore NAND backup.

I went with #1, told them I dropped my N3DS in the pool and needed to restore my NNID. All they asked for was both serial #s and some purchase history to verify my NNID. Then after 24 hours, voila, I got an e-mail saying the account was re-linked to previous N3DS and I was able to sign in.

I decided to invest in an old O3DS that I'll specifically use for this purpose.

Cheers for the responses anyway
