Hacking Downgrading 3DS fatal error 0001001 SOLVED

[Ronhero]

So I need to format emuNAND again to have my emuNAND on the 8.1 again then use 3dnus to create a 8.1.0-19... How should I created 8.1.0-19 files? as cias? And where I can update all of it?

After that I lost on your words, man.

Could you please help telling me this step by step?

I know the MC web is down right now.

Please help me, man.

**** THIS IS FOR Old 3DS and Old 3DSXL ****

For fatal error 0001001, Here is a simple safe way to upgrade then to downgrade for firmware <9.3 (I learned through experience of using different methods):

1. Use 3DNUS to download <9.3 firmware cias (prefer newer than your current firmware if <9.2). Then create "updates" folder on the root of SD. Then copy all firmware cias downloaded by 3DNUS into "updates" folder. https://gbatemp.net/threads/3dnus.376488/

2. Download https://github.com/profi200/sysUpdater/releases ( Don't use 0.4b ). And put sysupdater cia on the root of SD.

3. Install Rxtools https://gbatemp.net/threads/release-rxtools-roxas75-3ds-toolkit-fw-2-0-9-2.382782/ . Then inject FBI to SYSNAND.

4. Boot to Rxtools menu. Then Boot into DevMode. Use FBI to install sysupdater. Use sysupdater to upgrade (still in DevMode). Make sure you are in DevMode all this time in step 4!

5. Follow the tutorial video made by @DarkFlares to downgrade to 4.2 using Gateway launcher.dat and Gateway.dg http://www.gateway-3ds.com/downloads/


***Note 1: Step 5 (video tutorial) is all it needs to downgrade. The upgrade part is to safely fix fatal error 0001001.

***Note 2: If you want to keep your EmuNand, follow this guide before doing all the above steps: https://gbatemp.net/threads/how-to-transfer-emunand-to-another-sd-card-working-on-new3ds.383684/

Can someone give me a guide to re-link SysNand and EmuNand?

It depends of how you unlinked them :
- if you formated your sysnand : just restore your nand backup.
- if you did a system transfer : transfer the movable.sed and the ticket.db from your emunand to your sysnand.

Hello,
I've tried to download the firmware with 3DNUS, but as Nintendo retired the files I'm unable to continue. I cannot downgrade because of the fatal error. Does somebody have the firmware files on internet for 4.x, or what can I do then to install the profile exploit in order to run fxtools without connecting to internet ?!

Thanks in advance !

Google that ISO site 3ds
Go to the CIA downloads section
Find the update and DLC subforum there and you should find a post right at the top that has backups of a TON of update packs and browsers and stuff
