Homebrew Sysnand Backup after Downgrade to 9.2

[_phlo_]

Hello fellow GBAtemp members

I wanted to ask if you can backup your Sysnand after you downgraded from 10.3 to 9.2 or if it gets wiped after the downgrade process and I have to start all over with streetpass or so

What are you using to backup your sysnand?

Nothing at the moment I am looking/searching for a way to back it up

 

[tony_2018]

its going to require CFW and devmenu to install this app that backs up your sysnand.

Ok Question 2 does downgrading wipe sysnand

I think you can use EmuNAND9 to backup your SysNand. I have used this. I followed this guide.

For your second question, I don't know.

Yes, EmuNAND9 will back up sysnand. It can back up and restore emunand, too. If you want to restore sysnand while it's unbricked, you can use Decrypt9 or Gateway Launcher to do that. Otherwise, you'll need a hardmod to unbrick, with a copy of your NAND on your computer.

And yes, downgrading will attempt to replace all of your internal NAND files (if not, most. pretty sure it doesn't downgrade like 2-3 files depending which region/model your 3ds is) with the 9.2 firmware.

If you use Julian's sysupdater, NATIVE_FIRM will be written to last. tux's version writes NATIVE_FIRM first, which is more dangerous, and yet I've heard a lot of success with that build.

Or I transfer all the data to my old 3ds and downgrade the N3DS and system transfer it all over will that work ?

If by transfer you mean "manually with SDF/svdt" then yes. If you mean system transfer through system settings, then no: You cannot officially transfer N3DS back to O3DS.
