From 9.2 (or any lower firmware) to CFW 4.5, without Gateway

Preparation

Hardware Requirements:
  • A Windows PC
  • A 3DS on 9.2 or lower
  • A SD Card reader or some other adapter to allow you to copy files from your PC to the SD
  • A DS flashcard that works on 4.5 (R4i, etc),
  • A SD Card (preferably 16 GB to hold games, but even 4 GB should work)
Software Download Links:


Part 1 - Downgrading

  1. Copy the Gateway Launcher.dat and Gateway.dg file to your SD Card.
  2. Turn off wifi and open the 3DS Browser. Go into the settings and delete cookies/cache.
  3. Optionally, reboot your 3DS.
  4. Navigate to the browser with wifi on this time, and go to go.gateway-3ds.com.
  5. The exploit will now load. Go over the options using the D-Pad and backup your NAND.
  6. After the NAND backup is done, power off the 3DS by holding down the power button. Put the SD Card into your computer, and copy the NAND.bin somewhere safe. This is your fail-safe, so don’t lose it!
  7. Put the SD card back into the console, with the NAND.bin still on it.
  8. Go run the downgrade process (it’s the last one in the menu). Wait for it to finish. Once it’s done, reboot your system. Put the SD card into the computer and ensure Launcher.dat is still on it. Do not delete NAND.bin just yet.

Part 2 - Installing CFW

  1. Now, copy the GW Installer DS file to your DS flashcard. Pop it into the console and run that file from your flashcard. When it’s done, press home and go into System Settings. Go into other settings —> profile and tap DS Profile. The Gateway menu will load once again. This time, run the format emuNand process. When it’s done, shutdown your 3DS.
  2. Pop the SD Card back into your PC. Run the emuNand tool you downloaded earlier and press “Extract emuNand”. Save the file as emuNand.bin somewhere.
  3. Now, drag the emuNand.bin onto the bat file that was downloaded. After a while, a resulting REDNAND.bin will appear.
  4. In the emuNand tool, press “Inject NAND into emuNAND”. Select the REDNAND.bin file, and just ignore the warnings about not finding NAND.bin.
  5. After it’s done, delete everything on the SD card. It should only be a LAUNCHER.DAT file.
  6. Now, copy everything from the SD Card folder in Palantine CFW onto the SD card. Delete the launcher.dat, and rename the launcher_gw.dat to launcher.dat
  7. Insert the SD card into the console and boot up. It will create software management information. Take the SD card out again and open it on your computer.
  8. Now, in your SD card, there should be a Nintendo 3DS folder. Open it, and open the folder inside that. There should be another, so open that too. You should see a exdata folder.
  9. Make a new folder (not inside the exdata folder, but in the same directory as it) called “dbs”. Go into the folder and make a blank text file, named “title.db” or “import.db”. Doesn’t matter which.
  10. Insert the SD back into the system and go into Settings —> Data Management —> Software. It’ll ask to reset your software management information, so allow it to do so.
  11. Now, go into Other —> Profile. Hold down the L button, and tap DS Profile. If all goes well, the bottom screen will flash white and the CFW will load. If not, simply reboot the system by holding down power and trying again. Make sure to hold L while you do it.
  12. Now, once you’ve gotten into CFW, you’ll need your 3DS’ IP Address. You can use the tool you downloaded earlier (the network scanner) to find the devices from Nintendo. Note the IP (usually looks like 192.168.1.1xx)
  13. Edit the run.bat file in the Palantine CIA folder. Replace the DevMenu_2x.cia part with the name of your CIA, and the IPTOMODIFY with your IP.

Code:
installcia IPTOMODIFY 1 DevMenu_2x.cia

Code:
installcia 192.168.1.155 1 DevMenu_2x.cia


22. Now execute run.bat by double clicking on it. It should return result-code of 0.

  • If you get a failed to connect, make sure the IP is correct and the 3DS is connected to the Internet.
  • If there’s another return code, try steps 8 and onward again.

23. Once you’ve succeeded, press Power —> Home and unwrap your new gift. You can now enter the CFW without holding L using the regular way.

Installing CIAs

  1. Find a CIA to install. Google is your friend.
  2. Copy the CIA to your SD Card.
  3. Use the standard method to get into the CFW. Open the DevMenu and import away.

Yeah, but not for 3DS games.

I haven't been keeping up with the scene like I should be...I read that you can install older games through CFW which is required to install these .cia files. Im not sure how old the games have to be (something about 6.x encryption or something or another) which is my current goal as I have no way of obtaining a Gateway just yet. Id be fine with installing .cia in my emuNAND (please correct me if anything I am saying is grossly incorrect)

You're correct there. Any game with under 7.x encryption (basically any game before Smash) will work in the CFW. But IMO the CFW is very very trash and it just refuses to work on my unit, weirdly enough.

Yeah if it wasnt for the fact that I barely play on my 3DS (and plan on getting a n3DS) I wouldnt be attempting this....Ill probably just update back to 8.1 for my retail Smash until I can afford a DS flashcart for CFW (or a Gateway). Thanks for your help/clarification.

It's actually possible to have a 9.4 emuNAND alongside the CFW, using 2 different SD cards.
Look no further than here for a guide.

Last Night I helped my friend Downgrade and Install EmuNAND however we had some Issues

Downgrade - Success
Install EmuNAND (4.2) - Success
Updating on EmuNAND - Success
Booting 9.5 EmuNAND - Failure

We were unable to Boot the 9.5 EmuNAND using the Gateway Launcher however it booted using the MT Card Launcher although after my friend redownloaded an eShop game on the EmuNAND (Which was linked to the Nintendo Network ID) The eShop game would not boot (Zelda 4 Swords Anniversery) How does one fix this please?

Hey can you give me some advice, the run.bat cannot connect no matter what I try. Ive tried several times of booting into the cfw and changing the IP address in the bat file to what it shows me on wnetwatcher but it keeps failing to connect. Also my 3ds will freeze to a black screen if I load anything while in the cfw

New problem, on attempting to enter the CFW through the DS profile (much later on) I just get stuck with a blue top screen and black bottom screen.
I wasn't able to have the old LAUNCHER.DAT in the same folder with Palatine's launcher.dat (previously launcher_GW.dat), is that a problem?

EDIT: and running the blue card program again made it work, somehow. Neato, thanks for the tutorial! :D

EDIT2:
um.. I rebooted my 3DS and now the BigBlueMenu app is gone. And holding L on the DS profile just errors

Can anyone help me on running anything like this on a 2DS? i heard from some friends of mine that it were possible but just not as easy to do as most consoles.

It's the handheld that came with Pokémon X, don't know for sure if it was ever on 4.5 . all that i've read has pointed out that this is not possible, but i'd still try to know for sure.

If anyone could help me i'd be eternaly thankfull.

Thanks in advance

yeah I went through all the steps and got it to install BBM again but it's gone away.. What's the deal here? Do I need to go through the DS profile every time I want to get to CFW?

Is it possible to still play my higher firmware retail games now, or is it one or the other? I'm afraid to open the eshop now

EDIT: and I've figured out the alternate card for higher emunand thing, but I still don't understand booting into CFW. Do I need to run the profile exploit every time I want to go to CFW? Is it normal for it to crash all the time?
EDITMORE: every time I update my extra emunand card, it gives a black screen when I enter GW classic mode. Is it important to use the MT bootloader instead for that?

I need help. I did all the steps successfully until I need to install the GW_INSTALLER.NDS.

I am using my DSTWO. And when I try to use it I get stuck at this part. Can anyone help?
