ROM Hack 3ds Backup NAND question :(

[TomD21]

What's up guys!!! I'm new on the site, and also in the business of hacks 3ds. I already know about the risk of brick, if you make something wrong. So already sought assistance here if brick. The guy who makes the unbrick here uses hardmod but said it must have the backup of the NAND, and my 3ds is at version 10.5. I just thought means to backup versions below 9.2, and need the NAND backup before making arm9loaderhax + luma. How do I backup?
Note: sorry any mistake, I'm on google translator '' -.-

So you're on 10.5 correct? If so, use this guide to downgrade to 9.2 https://github.com/Plailect/Guide/wiki you many downgrade to 9.2 before you can back up a 9.2 nand.

Follow the guide @nero99 linked you, it will teach you how to make backups.

Thanks guys for the answers !!! But I have another problem here, I did downgrading to version 9.2 and reinstalled the menuhax as shown in the guide. I'm getting into the emuNAND, but when I choose the 'backup sysNAND to file' option appears ': failed'.
