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.

Did you play or use a DS title? You'll have to reinstall the exploit.
Yeah I did and I ended up reinstalling the exploit..But for the final stretch my install of BBM keeps failing


Now I am getting result code: c0a0002b everytime I run the .BAT file

AS I am redoing the entire process I have to ask, what do I do with the ENUNAND file after injecting it with the RENAND?

EDIT: Nevermind I have successfully installed Bigbluebox!!

try disabling the firewall let me know again if failed to connect again

Hey thanks for working through this with me...

So, I disabled firewall on 2 PCs and router (DD-WRT), still getting exact same thing - almost instant "failed to connect"

Here is a screenshot showing my run.bat file, the 3DS clearly active on my network and the command window with the connection failure message:

try to change first your ip on 3ds if failed again, try it on a laptop 100% working... i'm having issues on transferring from desktop to 3ds same as you, then i transfer my devmenu on laptop no issues at all.. and take note Hold L button while entering CFW this will enable transfer mode (palantine cfw only)

Hi guys , i just went thru all the steps and now i should do :
  1. 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)
  2. 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.
I took ip address of 3ds from my router settrings , edited bat file , but when im trying to run it it says:
ctrclient.exe- system error
Cant run the program because file MSVCR110.dll is missing.

Google says its one of microsoft visual c++ file , I re-downloaded it .
But its still the same keep getting that error. Any ideas ?

edit: Just tried on 3 different laptops , same thing on all of them

You'll need to download/update the latest MS VC++ framework which can be found HERE.

Unless you're running Windows XP, you should be fine with the 64 bit installer if it gives you the option.

Hi, I lost my nand.bin's backup and I have already formatted my sysnand. Can I use the emuNAND.bin generated from my old nand.bin to restore the old sysnand?

I haven't progressed past the issue I described above - been busy with my Vita last few weeks, might try the whole process over on another PC today.

One thing: do I have to have an eshop app in my sysnand for this to work?

I have SM3D land on emunand (rx-e 9.6), but no eshop content in my 4.2 sysnand.

Hello everybody, I have a question, if i buy a Nintendo 3DS XL Nes Edition (It probably come with firmware version 7 o 8 I don't know exactly), Can I downgrade to 4.5 for install a CFW? Or Can I only use Gateway/sky3ds flash card?

Yes, as long as your 3DS is on FW 9.2 or below, you can use the Gateway downgrader tool.

Guys, quick question:

I'm on 9.2 and every time I try the Gateway web exploit it fails to load the page on my 3DS and says I need to restart the console.
Anyway to overcome this?
