Worked on N3dsXL EUR last night. Fairly easy once the sysupdater app worked I did have to reset my 3ds MANY times to get to the sysupdater main menu screen so be patient or wait for a better way to do this. People looking for the cia files google [MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions) click 1st link then find the thread with the same name as what you searched.(use your brain...) READ THE THREAD CAREFULLY SO YOU DON'T USE THE WRONG CIA FILES.

 

[MarioBrosThe]

I think I may have something up, but when I tried to downgrade, it took less than 10 seconds, and when I went to system settings to check out what version I was on, it still said I was on 10.3. PLS HELP.

 

[Bat420maN]

Ok, I got my 3ds to boot up without holding down L. Now I have no way to get back into the homebrew menu. Browserhax is not working at all. Do I have any other options?

 

[amitors]

Do you used this version:
https://gbatemp.net/threads/tutoria...ngrading-your-3ds.407888/page-95#post-5923820.
Do you used the CORRECT cia

SO far its seems to be a hardbrick

I used the version in the 1st page of this post, I think that is not the same. There is something I can do if it's hardbrick? I live in Argentina and Nintendo does not provide technical support here

 

[zezzo]

Use SAFEMODE. Press L+R+A+DPAD-UP+POWER to boot into SAFEMODE and update your 3ds

What is the chance of brick? 3ds xl USA on version 10.3

 

[Substance12]

One question, do I have to uninstall menuhax before formatting?

Make sure the .cia's are not in another folder. I had just extracted them and they were already in a folder so I had updates\updates\then all the cia's. Got the same thing as you till I realized it.

@TheStoneBanana You should add the md5sums of the zip packages from that iso site and a step to check that the downloaded zip is the correct one (by comparing the md5sums).

This is a great great GREAT idea! Working on it now.
I do have a question though, because lots of people have been PMing me about the CIAs. Am I allowed to give a specific search term that you can use to find the files, or is that against the rules?

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

 

[groopkio]

i tried for almost 12 hours ( twice a minute ), and sysupdate stuck at #5 : restoring slabhead backup...

Dude, this is awesome!
Do you mind if I add it to the OP? (giving you credit for compiling it of course)

 

[MarioBrosThe]

Make sure the .cia's are not in another folder. I had just extracted them and they were already in a folder so I had updates\updates\then all the cia's. Got the same thing as you till I realized it.

I had no CIAs in any folders at all.

 

[ombus]

executed sysupdater and its black screen never letters what do i do

 

[Zedjones]

This one uses SULib instead of libkhax. Hopefully it will work now

USE THIS WITH YOUR OWN RISK!!!

Finally! After trying the Steveice10 fork and having it fail for hours, this build worked on the 5th try with Ninjhax. N3DSXL 9.9 to 9.2 successful!

 

[Hyura]

I had no CIAs in any folders at all.

And you expected it to update? wtf

 

[Khaeroth]

Hello pals. I have a few questions.

First: I have a USA O3DS Ver. 10.3.0-28U

-This works in my 3DS?
-What do you lose when you downgrade?
-What do you need to do the downgrade?

Thanks (:​

 

[Ushiara]

It's OK for me (10.1 -> 9.2). I've use Cubic Ninja and @julian20 's build

 

[bi388]

executed sysupdater and its black screen never letters what do i do

So you never got to the point where it installs CIAs? Try a different entry point and redownload boot.3dsx

 

[MarioBrosThe]

And you expected it to update? wtf

Because, I couldn't find any fucking CIAs? I'm sorry if I sounded stupid, but where can I find some CIAs?
