Homebrew For everybody wondering whether or not it is safe to downgrade - Here is a statement from TuxSH

[RoyalLemons]

If it's an (E) then it's an (E) what you are looking for. As you can see here, Australia works as a European country in this case.

There's always a risk, but apparently if your 3ds were to brick, it could be fixed (Use this release for that : https://gbatemp.net/threads/simple-guide-to-downgrading-your-3ds.407888/page-95#post-5923820)
I downgraded a 3DS a few hours ago without issues, just be sure to doublecheck that you have the correct files.

If you downgrade, you can update your emunand to the latest version and play online without problems.

Awesome, thank you!
I assume if online play works with updated emunand then local play would as well?
I read somewhere that separating emunand and sysnand requires a format and I figured I will lose all my currently installed games, software and saves. Is that true? Will the system still recognise the games installed on my SD after a format (obviously formatted with the SD not plugged in)?

for rxtools it certainly is. i went ahead and took the risk without a hardmod anyway. if you're thinking of doing it and have eshop content you should back it up on a pc, i did a clean install, backed up my sd and formatted, got the starter kit from smeas page, placed sysupdater in 3ds folder and extracted the ttp file from a link in justpingo's twitter account post, which i then placed in the update folder on the root of the sd. i installed menuhax and then everytime before i ran sysupater i would run ftbrony and exit. it doesnt matter where you get the downgrade files as long as they are the correct ones for your region and as long as they are not corrupted in any way. i took another risk and used 7zip to extract the TTP file with 7zip despite justpingo saying it wouldnt work, and when i downgraded with those cia files i got no soft-bricks and ended up with 9.2 firm

Okay thank you.
If emunand were to be at 10.3, would booting RxTools into that not work?

I apologise if my questions sound silly.

not sure i understood the question well but as far as emunand goes on a new 3ds its limited to firmware 9.5 from what ive read :/ but online play works fine without latest firmware since updates and dlc can be installed as a .cia and as far as local play goes i havent tested it but i believe it does since i have a sky3ds and would always play starfox643d on local play with that cart. and like darklinkpower said in case of a soft-brick you can hold up dpad+A+L+R and boot into recovery. i got 2 soft-bricks with the ISO files but with justpingo's extracted ttp i was successful.

Yep that answers that.

Will I lose my games and saves, etc? I'm sorry if this has been answered, though this hasn't been particularly evident. If I perform a format for emunand and sysnand without my SD card in the system, will I lose them if I put the SD card back in? Or will the 3ds just read all of the content like it would before unlinking?

 

[SterneSchreien]

Successful downgrade attempt after 4 softbricks here. Only variables i changed were NO oldDS cartridge in the console (was Castlevania POR), console was plugged this time and I used a 16gb Lexar Class 10 SD card (SDFormatter formatted) instead of the 4GB one that came with the console.

Also I force closed FTP-3DS before launching sysUpdate every time but I don't think it did much of a difference.

as far as sysnand goes i did not lose my games/saves linked emumand either but as far as unlinked im not sure. it would be a pain depending on how many saves you have but you can back them up with save data manager on HBL and restore them on emunand.

That's a pretty good idea. Thanks!

Ohhhh sorry, didn't see you were on a N3DS. Those can only be updated up to 9.5 emunand, but as far as I know, you can play online without problems.

Yeah, to separate emunand and sysnand, you have to do a format, on either emunand or sysnand, you can format in the nand that you DON'T want to keep your current games and saves, for example:
Format while in sysnand --> You keep your files to use in emunand.
Format while in emunand --> You keep your files to use in sysnand.

What happens when you format emunand, is that your exact sysnand gets copied to the SD. Since they are the same, they use the exact files on the SD (they use the same ID inside "Nintendo 3DS/random numbers"), so when you format either, that NAND gets another ID to use, and the one that didn't get the format, keeps using the old ID.

Remember to backup all your SD before formating your emunand, since it gets wiped in the process, you have to copy them again later.

So if i were to format while in emunand then transfer all backed up files from my computer back over to the SD, i'd essentially lose nothing? or am I missing something?

So basically if I understand this correctly once I downgrade to 9.2 on my Sysnand. I boot up my Homebrew *hax 2.5 from my 9.2 sysnand and install a cfw to my Emunand that will be running 10.3 or higher.

So in a nutshell if I ever booted up my Sysnand I'd be on 9.2 but through my Emunand and CFW I'm on 10.3.
Are the two nands linked by default and I must unlink them or is that something I don't have to worry about?

How does FBI know where to install .cia??

Yes, your sysnand would be 9.2, while your emuNAND could be updated to 10.3 (Only if yours is a O3DS). They are linked by default, but I'd suggest to unlink them in case that you mess something up while in emuNAND, because it could affect your sysNAND. IIRC, there have ben cases where people tried to update their emNAND, but what got updated was the sysNAND. Better be safe than sorry.

Here's a guide to setup everything: https://gbatemp.net/threads/tutoria...ncluding-emunand-coldboot-cia-manager.405589/

You'd lose the ability to use your old files while in emuNAND, nothing more. They'll work fine in sysNAND.

 

[RoyalLemons]

Forgive me for sounding daft.
Is there a way to downgrade, unlink sysNAND and emuNAND, install CFW + CIA files while also keeping my access to the eShop & my games i've downloaded and played throughout the years? There's so many aspects to everything that it's just gotten a little confusing on what is and isn't possible.

You didn't format the 3DS itself? Also, in the SDFormatter, did you do a quick format or a full format?

Didn't format 3ds, only SD. FULL (OverWrite) option in SDFormatter.

"The latest version as well as a good tutorial can be found here. (this links to latest version, with Steveice's changes)

Changes has been made by Steveice so that nobody shoud experience a full brick again (i.e. the 3DS doesn't boot, even in safe mode). Thus, this version should be almost brick-proof.

Menuhax users will have to remove their extdata folders 00000082 (JAP), 0000008f (US), 00000098 (EUR), after downgrading.

By the way, I've deleted my sysUpdater fork repo on purpose."

reddit link: https://www.reddit.com/r/3dshacks/comments/3zl47b/please_use_the_latest_version_of_sysupdater/

The link you provided, is Steveice's new Build on First page with the tutorial? Or on another page somewhere? I don't want to make the mistake of using an older build.

10 hours later, still no success getting past the sysupdater 0xD900182F error. It would be helpful if the program displayed the debug to see if it has even gotten kernel access, because that is most likely what is not happening. None of the voodoo dances of starting apps beforehand, reformating, etc are changing the result. Seems the N3DS XL has issues with the exploit completely at this point, as it took this amount of effort to get one attempt for the FBI CIA installations too.

It only gets worse.. I haven't gotten a non blackscreen in around 25ish tries.

The one on the first page is updated, I used it and i downgraded.

Does anyone know if there's any development in progress to update emuNAND beyond 9.5 (if possible at all) on a n3DS?

Ugh. I'm still having difficulties. I have a Sony 32gb class 10 I formatted fully using SDFormatter, no cartridge the slot, plugged into power, clean SD besides the downgrade files, opened FTP-3DS before downgrading, and I still freaking soft-bricked. Advice? Tips? It's driving me crazy.

Specifically speaking, how does one backup the sysnand? Asking because I am assuming it isn't as easy as copying over the files from the N3DS' native file access service via your network? How'd you back it up

So basically if I understand this correctly once I downgrade to 9.2 on my Sysnand. I boot up my Homebrew *hax 2.5 from my 9.2 sysnand and install a use this guide [Tutorial] Installing rxTools Custom Firmware - (3DS and 2DS) to install cfw (if i have a n3ds i use this guide instead [Tutorial] How-to install a CFW on a 9.0-9.2 N3DS without CN/OOT) to then update my Emunand so that will be running 10.3 or higher. (if i have a n3ds i use a different version of sysupdater to update emunand to 9.5)

So in a nutshell if I ever booted up my Sysnand I'd be on 9.2 but if booted through my Emunand and CFW I'm on 10.3. (but if its a n3ds 9.5 will be my emunand)
Are the two nands are linked by default and I must unlink them or is that something I don't have to worry about?

How does FBI knows where to install .cia?? because i tell it where to . . . but i should look for bigbluemenu.cia (a cia installer that's smarter than fbi)

fixed it

either with a hard mod (any fw) or with gateway launcher (9.2 or lower only)
