Tutorial Simple Guide to Downgrading your 3DS

[Jimmothy]

Must've tried about 50 times now using MenuHax on the sysUpdate on two different SD Cards.

Setup:
New3DS 10.3.28-U
Formatted FAT32 Sandisk 32GB SD Card
Formatted FAT32 Samsung 16GB SD Card
Exploit: Browserhax / Menuhax
sysUpdater 0.4.2b by profi200 (The one posted by @julian20)

Either get a black screen or the "Failed to get CIA file info!"

Double-checked everything with the MD5 Checksum and having the latest sysUpdate.

I just downgraded and installed CFW!



Almost brand European N3DS XL 9.4 -> 10.3 -> 9.2 -> RX 9.2

Downgraded using @julian20 's sysUpdater - After maybe an hour or two of constantly trying different things.
Open ftBRONY first, Open CHMM2 first, Wifi ON/OFF, Cartridge in/out, using sysupdate as boot.3dsx etc.
I think in the end it was just a random boot up, open and close either CHMM2 or ftBRONY and then the updater.

For CFW i used @wurstpistole 's [Tutorial] and it went smoothly! (Except for errors on my end ofcourse. I forgot to remove SD card when system formatting while unlinking NANDs)

Congratulations to developers

I'm almost as excited as i was for the original GameBoy ~19 years ago! (Profile picture)

Do 3DS XL and the smaller use the same fw? I don't know.

 

[Tyler Martin]

its said it couldnt get cia info

 

[wally92]

Does this work on a 2DS on 9.8?

Yes they do, one FW for all o3DS [also used by the 2ds] and one for all n3ds.

Hows the risk of bricking on a New 3DS at this point in time? Will this process require me to wipe my SD card and my games along with it? Is there a guide to unlink the emuNAND so that I can be on 10.3 as well as 9.2? I don't want a $200 paperweight, or to lose my game save data.

You will need to wipe your sd card to create emunand at least yes. Nothing to stop you copying the files elsewhere first and then copying them back later though. I would recommend looking in the guides section for something that suits you, unlinking sysnand and emunand is one of the easier parts when you get to it, all you do is system format the 3ds. For physical cartridges the saves are stored on it, for downloaded games you would need to backup the saves asap.

Where are the save files located if the games are already backed up. Do you need a specific program to extract them, or is the ability already built in?

Hi I just wanted to confirm that the 2ds is on o3ds firmware. I just got back into the scene and could not find a definite answer. Thanks

I am not happy when I do a search and it's the first item in google. It makes me think you are lazy.

This isn't an advisable process for newbies though, nor is downgrading your 3ds.

I'm sorry for that. I can't use google in my region and other search engines have nothing useful info of this. sorry again for your inconvenient.

Just wanted to note that I've tried the OOT3DS Hax about a dozen times with the same results.

i wonder if sysUpdater 0.4.1 would work since its the newest stable release

Well that really sucks, if you are in china don't you have Baidu or something? I take back my annoyance.

In any case be careful doing this stuff unless you really understand it. This whole forum is more for education than anything.

If I am to downgrade my o3ds and create an emunand is there any way I can unlink my sysnand and emunand without losing my sysnand data and saves?

 

[Santaros]

For downloaded games the saves are stored in nand, you would be using something like:

svdt

or Save Data Filer [I dont think I can link]
