Thanks. Do I have to redo every single step listed there? A bunch of that stuff seems to concern writing to internal memory, and therefore wasn't lost with the SD data in the first place.
After you sort out whatever or not your SD card is going bad, keep your Nintendo 3DS folder and backup the games saves + extdata with Checkpoint/JKSM save manager the first moment you get. Corrupted titles will require fresh installations; be warned reinstalling a game will overwrite whatever save you had in place.

It would be wise to create a new (clean) SysNAND *.bin image for brick recovery purposes. First time CFW'ed 3DS users often fail to do CTRNAND Luma3DS where they mis-attribute black screen boot without SD card as a brick.

Yay, my advice is just redo everything in Finalizing Setup. If you use the CFW starter kit, you may want to selectively install titles found in the cias folder if you prefer homebrew apps on HOME Menu.

Okay, will do. Do I also need to install Frogtool so I can revert Download Play back to its original state?

I haven't touched the 3ds scene since about june 2018. Anything I should know or do?

Perhaps update B9s and Luma?

Are tools still installed via .cia?

Thanks.

Okay, I have a problem-- when I try to load the Homebrew Launcher through Download Play, the system crashes ("an exception occurred"). What do I do now?

Edit: Lol never mind, I was following the guide too literally and had forgotten to copy the boot files to the SD. Works now!

Wow, thanks a lot. That's a very precise answer. This is what I suspected without knowing all those interesting details (unfortunately after I bought a Sky3DS+).
I also tried citra. It's very nice and effective, but I really would like to play on a physical 3DS.
So here's another question. B9S is a custom firmware that can be booted from SD card with an exploit, right?
What I am aiming at, if I can't run patched games on an unmodified 3DS, is a way to do it that can be reverted, so if everything is on the SD card it would be perfect for me.


Short answer: No.

Long answer: An unmodified 3DS will only run software with a valid (legit) ticket/signature; the software has to be signed with a private key – surprise, surprise – only Nintendo knows. Since you are talking about unofficial patches: No way to get a valid signature for that.
  • Expensive flashcarts (Sky3DS+, Startgate) can emulate a retail cartridge, including signature. This works on unmodified 2|3DS consoles as long as the (.3DS) ROM is unchanged and has the same region as console.
  • You can install universal legit .CIA files by booting CFW once with ntrboot. The games installed this way will work without permanent installation of B9S.
Both ways above are not applicable on patched games because any modification makes the signature invalid.

Other than personal preference ("I do not want to do this!") there are no reasons for not installing B9S and Luma I can think of.


Maybe the Citra emulator is an option for you

If I want to update Luma should I update Luma Updater on SD first?

--------------------- MERGED ---------------------------

Oh, it seems to be able to self update

Jeepers, really? You can chainload Luma from ntrboot? I thought only gm9 worked that way. Is this documented somewhere? (I can see why this is obviously not recommended and I will not spread this knowledge around, but I'm very curious.)

No, B9S is installed to the 3DS internal storage, and even a standard 3DS System Format can't get rid of it. B9S boots Luma, which is usually on the SD card (and can also optionally be installed to the NAND).

What I am aiming at, if I can't run patched games on an unmodified 3DS, is a way to do it that can be reverted, so if everything is on the SD card it would be perfect for me.
There are instructions in the Guide for uninstalling B9S, but it carries significant risks and is usually not recommended.

Someday perhaps new and different exploits will be revealed, but there are some that are (apparently) being held in reserve until it is clear that Nintendo has no further interest in updating the system.

I'm going to buy an used 3DS tomorrow. I do not know the firmware. According to the 3DS Guide, no matter what the firmware version is, I should update to 11.10.0. From what I've searched online, it seems the latest 3DS firmware is 11.10.0-43.

Does the "-43" does not matter? Does this literally mean that tomorrow, as soon as I come home with my beautiful, gorgeous 3DS, the first think I should do is to actually connect to the internet and - gasp - update it??? Is that literally it?

If it is on 11.3 or less, don't update it, because then you can use SoundHax.

Luma can do this (and you can chainload Luma from GodMode9 as well)
github.com/AuroraWright/Luma3DS/releases/tag/v9.0 said:
[…]
* The console will now shutdown when the shell is closed in the Luma menus, unless the user booted via ntrboot
[…]
But I do not recommend using this method of loading Luma if you already have B9S (really pointless anyway) because – as far as I know, FIRM0/1 protection is inactive when loaded via ntrboot → The official updater can overwrite B9S. See https://github.com/AuroraWright/Luma3DS/blob/master/arm9/source/main.c
Code:
isFirmProtEnabled = !BOOTCFG_NTRCARDBOOT;

OK.
So if I understood, there is no way to run non-legit CIA/3DS eShop images without modifying the firmware, and once it's done, a rollback is risky. I think I'm gonna buy a 3DS specifically to do that.
Last thing. I read that some hack on old firmware (which I have ATM) allows to run homebrew. Can you run non-legit games this way?

You can't run commercial games with plain homebrew. You need CFW for that. Lower firmwares just allow extra ways to install CFW.

Having CFW is not at all risky, and there's never any reason to uninstall it so there's no reason to be worried about that. The risky part of uninstalling CFW is if you modify any system titles (eg to have a custom sleep screen or region change), then those system titles no longer have a legit signature and if the 3DS no longer runs CFW it won't be able to run those system titles and the console will either not boot up or behave badly (eg having an error whenever the keyboard is opened). But, if all you do is play pirated games and don't modify your system beyond this there's no issue. And absolutely zero issue if you never uninstall CFW (which there is never any reason to do anyway).

That being said, there are a select few games that can be gotten as "legit cias" that will run without CFW once installed. If you are happy only playing those (and no patched roms or anything), and are capable of amending the 3DS guide instructions to just run FBI through homebrew which will only work on a low enough firmware (used to be 9.2 but probably works on 11.3 now), you can do it without installing CFW (you would want the experience of installing CFW on a couple of consoles first). But I wouldn't bother - there's no risks having CFW and everything to gain.

I've another question. Do .3ds decrypted roms (meant for Citra) work just fine if converted to .cia using the right tools? Or do the fact they're decrypted change anything? Do only encrypted .3ds roms work if converted to .cia, or doesn't it matter?

If it is on 11.3 or less, don't update it, because then you can use SoundHax.
According to the seller, it's on 11.6. ):

If you are already on 11.8, then it is safe to update to 11.10 through the system settings, and you will not lose your hacks.

11.10 requires that you have at least Luma3DS v9.1 installed, but 11.8 also requires v9.1 or higher, so that means you already have it. If you haven't already done so, it is recommended that you update Luma3DS to v10.0.1. You can check your Luma3DS version by holding Select when you power on the 3DS.

Thanks, I updated Luma, Luma Updater and the system, so now I have everything up to date but the games I have installed are not updating. It downloads the update but it's like the doesn't install. How can I update the games?

How much free space do you have on your SD card?

As has already been mentioned, you can update it to 11.10 and use Seedminer. Soundhax is in some ways preferable but is by no means necessary.

Are you trying to download updates from the eShop for games that you installed with FBI? Because I don't think that works; if I'm not mistaken, you need to find the CIAs for the updates.

You can download and install game updates from the eShop, regardless of how the base game was installed.

I have 5 gb free space. It says "update data downloaded. you can check the data in system settings>data management>nintendo 3ds>downloadable content." but when i go there, there is no data.

If you go into the eShop, Menu, Settings/Other, and Updates, which games are displayed? What happens if you download and install the updates from this menu?
