Tutorial Simple Guide to Downgrading your 3DS

[kyomagi]

so i tried the safe version and the part where it goes through 1-8 does not show up. but when i hit downgrade it said something about the cia failing

 

[BothyBhoy]

FUCK YES 9.2-20E N3DS and it worked perfectly (aside from getting into sysupdater itself)

Here is what i did:

Spoiler: Downloads/software/etc/formating etc

- formated my n3ds (had 10.1, updated to 10.3 then format)
- formated SD (32gb kingstone class10) with SD formater (format overwrite + formatsize adjustements)
- downloaded 9.2-20E firmware for N3DS
- checked md5 of above firmware via this site
MD5: 6dcca8fcbc9a28c82c2a4e5182f3acf8
SHA-1: e7c77bf205137167f1f1befa0c4db9d879a21a2e?
- downloaded this systemupdater which julian posted (SULib one) MIRROR
- downloaded starter kit for homebrew (from smealum site)
- installed TeraCopy to ensure nothing will be damaged via copy/paste on SD card

Once above is done then this:

Spoiler: setting up properly N3DS to downgrade

- put SD to pc
- copy everything lower via teracopy program! (it will show your option when you do it just via copy/paste like normally you do after you install that program)
- copy starter kit folder content to sd card
- copy sysupdater to 3ds folder in your SD card
- copy updates folder to your SD card once you unpacked your downloaded and checked via md5 sum FW
- get your SD card to your 3DS and set up your 3DS (date, time etc.)
- change your theme to something else and back to default (to ensure menuhax will work)
- do browserhax (scan QR code [L+R and then that left sticker] from this site)
- you should go into HomeBrew thanks to above
- choose menuhax manager and install menuhax
- restart your 3DS and hold L to go into homebrewlauncher directly

Once above is done you have properly installed homebrew on 10.3 and it is confirmed that all files are 100% safe to use (that FW you downloaded) and nothing weird should go wrong (it still has that chance though)

Once above was done i started sysupdater from homebrewlauncher.
Since memchunx doesn't work most of the time i had to try 7-10 times before i got #8 success and sysupdater menu.

Then i pressed Y, nothing happened for 3-5 seconds
Then cheking CIA files... or whatever that was for 10-30 seconds
Then it started to install CIA files
Then it got to autorestart in 10 seconds
Autorestarted (NO CRASH)
Booted into 9.2 system without problem perfectly (without taking out SD card)

In other words perfectly updated without single crash (aside from getting into sysupdate menu)

I give my humble thanks to whoever worked on memchunks, julian for this fantastic build and ton of other people that showed me way to ensure everything will work correctly (like teracopy, md5 etc).

Now i have 9.2 and i am wondering what should i do Good thing to wonder about

what a great place to be......am so glad for you......ive had 9.2 for a while now on old3ds....i got 2 new3ds to do but am waiting on official tools.....great fun to be had now.....though this could ultimately end nintendos support of 3ds.....it may just give up .....similar to the wii......hope not

I hope not. 3DS is the best handheld at the moment anyways. And it is just getting better.

i agree

Managed to get my O3DS downgraded from 10.3 to 9.2, but my N3DS XL is giving me grief now. I've downloaded the N3DS EU cia zip, extracted it multiple times, copied it multiple times, but every time I get "failed to get cia file info". Does anyone know why this might be happening?

 

[AquaX101]

which version of sysUpdater should i download?

 

[Deleted User]

when will it be safe

If I were you I'd wait a month or 2 just to be safe, I mean I got bricked and have to get it repaired.

The pic kinda sucks but thats all it does. Just black screen. I'm gonna get it repaired tho

So I downgraded and then reupdated now I'm nervous about redowngrading for a cfw.

 

[Pingu]

will this work for my old 3ds fw 10.1.0-27U i have homemenuhax btw

You could just wait. I mean we have kernel access so it (I don't think) won't be to long until illegit cias can be installed, leading to cfw on current version.

Soon™

Hi, 1 quick question. Is not needed to have active wifi while downgrading right? (thanks!)

Unless you don't want to re-update to 10.3 if something goes wrong, I'd leave it on.

I have managed to downgrade my O3DS from 10.3E to 9.2E. The problem I have now is once I have rebooted in to 9.2 and I go to the Settings Menu it stays stuck on the red 3DS screen. I have tried the downgrade a few times and the same thing keeps happening.

Does anybody know a way to fix this?

Thanks

 

[Alpuy]

has anyone hard bricked the console with the latest version of sysupdater?

 

[mepica]

Thanks! Didn't think on that

 

[Kafke]

Thanks! Didn't think on that

Make sure you remove TubeHax DNS if you haven't. Since if you have that on, it'll prevent you from getting the update from Nintendo.

6 hours and counting, failed to get cia info or black screen

10.1 -> 10.3 -> 9.2
O3DS - U

Confirmed working

First tried Steve's latest build and crashed before completing installation of CIAs. (Got black screen)
Rebooted w/o SD card, changed theme and booted into an incomplete 9.2 (No NATIVE_FIRM downgrade).
Updated to 10.3 via system settings
Redownloaded starter kit + boot.3dsx and grabbed julian's sysupdater
Browserhax -> themehax
First try with sysupdater hung on Step #5
Second try I got all 8 steps
Installed update cias + NATIVE_FIRM perfectly
System autorebooted and 9.2 was a success.
