Section 2 - Making your NAND Backup! ​

Section 3

Section 3 - Launch rxTools for the first time! ​



In the 3DSCFWKIT, go to the "rxTools 2.5.2 (only if the included 3.0 Beta 2 doesn't work)" folder and drag the firmware.bin and rxTools.dat to your SD card root. Should look like this: SD:/firmware.bin and SD:/rxTools.dat

With this version of rxtools, you have to launch rxtools through the browser with this URL: launch.rxtools.net

If that launch URL is down, use this URL: http://dukesrg.no-ip.org/3ds/go/?rxTools.dat

Or this: http://www.reboot.ms/3ds/

You can hold R while rxTools is loading to get into the rxTools menu.

You can hold X while rxTools is loading to go directly to rxmode SysNAND (do not use this to run SysUpdater please!) If rxTools 2.5.2 is working for you, then continue to follow this tutorial as normal (Sections 4 to 7) Once you completed Section 7, I recommend that you update your sysnand to 9.2 so that you can use rxTools 3.0 and any future releases. Look at the section "How to Update your 3DS/2DS to 9.0 or 9.2" in this tutorial to see how. Take the warning SERIOUSLY. If you've successfully completed the tutorial and updated your sysnand to 9.2, quickly re-read this section so that you know all the ways you can launch rxTools 3.0. If you've tried launching rxTools many times and you are always greeted by an error, and if you are below 9.0 firmware, there is a chance that your 3DS is, for some reason, unable to use rxTools 3.0. To overcome this issue, you must use rxTools 2.5.2: Click to expand...

Section 4



​

Section 4 - Installing a CIA Installer

In the web browser, go to either:

go.gateway-3ds.com or

go.gateway-3ds.com/old or

http://www.reboot.ms/3ds/load.html?Launcher.dat

to launch Decrypt9WIP again. Alternatively, you can scan this QR code.

If you are using the Homebrew Launcher, simply launch Decrypt9WIP from there. Navigate to SysNAND Options and then Health&Safety Dump. Leave the name as hs.app and press A. Let the process finish. When it is done, "Press B to return" to the Decrypt9 menu. Press SELECT to unmount your SD card (so you can eject it without turning off your 3DS).

Remove your SD card and insert it into your PC. Go back to the 3DSCFWKIT folder and open the Tools folder. Open the Universal-Inject-Generator folder. Find the hs.app file on your SD and copy it to the Input folder that is inside the Universal-Inject-Generator folder. There will be a BigBlueMenu.cia already in there. Run go.bat. If there are no issues, you will find that there are two inject-ready .app files in the Universal-Inject-Generator folder.

To finally inject BigBlueMenu into SysNAND, take the BigBlueMenu_inject_with_banner.app file and place it on your SD card. Insert your SD card back into your 3DS, then "Press B to return". Choose Health&Safety Inject and enter the button combo; don't worry, it's not as dangerous as you may think. After entering the button combo, press Dpad Down to select the file BigBlueMenu-with-banner.app, then inject it. When it is done, simply "press START to reboot" your console. When you are in the 3DS home menu again, launch the eShop application. When you get the message "A system update is available! ...", press Cancel , then press HOME to exit back to the HOME menu. Then press Close to close the eShop. Now, launch the rxTools menu (hold L as rxTools is booting), and boot RXMODE SysNAND. You will be booted to what appears to be regular SysNAND. If you have Menuhax installed, you must hold R so that Menuhax will not load.

Navigate to the Health & Safety app and it should now be the BigBlueMenu app (Title Manager)!

If you notice any black "boxes" in your home menu, ignore them for now! It will not cause any issues. Launch BigBlueMenu/Title Manager. Go to the SDMC tab to view your SD card files. Navigate to the CIAs folder and install/import DevMenu_2x.cia and old3DS.AGB_FIRM.Patch.cia (if this one doesn't let you install, you can use the DevMenu app to install it) You just installed your first CIAs!

Section 5

Spoiler: Old method of installing a CIA installer.



You need to use rxTools 2.5.2 or above for this method! You can get 2.5.2 from rxTools.net, or follow the instructions from the section "How to Update to a Newer rxTools Version" to get the latest Nightly.



1. Boot up your 3DS and launch rxTools. Hold L when the bottom screen glitches to get into the menu. If you're using rxTools 2.5.2 or 2.6, hold R instead.



2. If using 3.0, press dpad RIGHT to go to Advanced Options -> Press A -> Install FBI -> Press A -> choose SYSNAND, then select "check TMD version".

If using 2.5.2 or 2.6, choose " Inject FBI over H&S app" and then choose "Install".

If you already have an EmuNAND:

Choose EMUNAND instead. Click to expand... If you get this error: "Couldn't find H&S TMD/content", looks like this method won't work for you. Click to expand...



4. Open the rxtools download and open the "Tools/fbi_injection/[region]/[version]" folder and copy the "fbi_inject.app" and "fbi_inject.tmd" files to the SD card root dir.



5. Put the FBI.cia from the FBI download onto your sd card



6. Boot up your 3DS and launch rxTools. Hold L (or R if using 2.5.2 or 2.6) when the bottom screen glitches to get into the menu.



7. If using 3.0, press dpad RIGHT to go to Advanced Options -> Press A -> Install FBI -> Press A -> choose SYSNAND, then select "Install FBI". When it's done, it will ask what you want to do with the source. Select "keep" if you want to install FBI to sysnand later.

If using 2.5.2 or 2.6, do the same as in step 2.

If you already have an EmuNAND:

Repeat lines 1-7 again, this time Injecting FBI to EmuNAND. Click to expand...

To boot into Sysnand: Hold L (or R is using 2.6) while rxTools is launching to get into the menu, then select RXMODE -> SYSNAND.

Hold X if using 2.5.2 and it will bring you directly to rxMode SysNAND; that is the only way to access it in rxTools 2.5.2. Click to expand...



Spoiler: If you get a Database error!



If there are two or more ID folders, then do the following steps for both folders. One folder is for your Sysnand and the other is for your Emunand; if there is another similar folder, it probably belongs to another 3DS that you inserted your SD card into. Ignore the "private" folder if there is one.



There should be another folder within, so open that too. You should now see an "extdata" folder. If you don't see a "dbs" folder as well, download beside the extdata folder.



*Again, if the dbs folder already exists, and you have a title.db and import.db file inside, do not replace them!



Should look similar to this:





Now, boot the 3DS/2DS and go into System Settings —> Data Management —> Nintendo 3DS —> Software. It’ll ask to reset or repair your software management information or sd card, so allow it to do so. Do this in Sysnand and Emunand! In your SD card, there should be a Nintendo 3DS folder. Open it, and open the folder inside that (has a long name of random numbers and letters); that is your Sysnand's ID folder.There should be another folder within, so open that too. You should now see an "extdata" folder. If you don't see a "dbs" folder as well, download this zip folder and put the "dbs" folderthe extdata folder.Should look similar to this:Now, boot the 3DS/2DS and go into System Settings —> Data Management —> Nintendo 3DS —> Software. It’ll ask to reset or repair your software management information or sd card, so allow it to do so.

10. You should now have a new FBI app on your home menu, use that to install your CIAs! Download FBI.cia You need to use rxTools 2.5.2 or above for this method! You can get 2.5.2 from rxTools.net, or follow the instructions from the section "How to Update to a Newer rxTools Version" to get the latest Nightly.1. Boot up your 3DS and launch rxTools. Hold L when the bottom screen glitches to get into the menu. If you're using rxTools 2.5.2 or 2.6, hold R instead.2. If using 3.0, press dpad RIGHT to go to Advanced Options -> Press A -> Install FBI -> Press A -> choose SYSNAND, then select "check TMD version".If using 2.5.2 or 2.6, choose " Inject FBI over H&S app" and then choose "Install".3. Take note of the console region and the TMD version, and turn off your 3DS.4. Open the rxtools download and open the "Tools/fbi_injection/[region]/[version]" folder and copy the "fbi_inject.app" and "fbi_inject.tmd" files to the SD card root dir.5. Put the FBI.cia from the FBI download onto your sd card6. Boot up your 3DS and launch rxTools. Hold L (or R if using 2.5.2 or 2.6) when the bottom screen glitches to get into the menu.7. If using 3.0, press dpad RIGHT to go to Advanced Options -> Press A -> Install FBI -> Press A -> choose SYSNAND, then select "Install FBI". When it's done, it will ask what you want to do with the source. Select "keep" if you want to install FBI to sysnand later.If using 2.5.2 or 2.6, do the same as in step 2.8. Now, return to the rxtools main menu and select RXMODE -> SYSNAND and launch the Health & Safety Information app, it should boot FBI instead9. Select FBI.cia and press A to install it.10. You should now have a new FBI app on your home menu, use that to install your CIAs!

Section 5 - Creating EmuNAND! ​

Section 6

Section 6 - Unlinking your NANDS

Using the recommended method of formatting SysNAND ​

You will not have to unwrap all your games whenever you enter emuNAND. This doesn't happen to everyone, but if it does, unlinking your NANDs will stop this from happening.

In the past, some users have reported their sysNAND updating even though they were sure they updated emuNAND. These same people happened to have linked NANDs. We don't know if it is related but it is safer to unlink your NANDs if you fear this may happen to you.

NANDs. We don't know if it is related but it is safer to unlink your NANDs if you fear this may happen to you. You can go into sysNAND's Data Management (found in the System Settings app) safely. Doing this while your NANDs are linked will result in your emuNAND games, saves, themes, etc. being deleted.

If you have Menuhax installed, you will not get a black screen when entering EmuNAND. You can bypass this by holding a button when launching EmuNAND (which will disable Menuhax from loading). But who wants to remember to hold a button every time?



If you want to play GBA games in emuNAND, you will have to install the GBA game in both NANDs, taking up double the space on your SD card. If your NANDs are linked, you only need to install GBA games in sysNAND once.

Your sysNAND will be formatted. Naturally, Devmenu2x will not be installed in Sysnand anymore, but it will be in EmuNAND. You can do Section 4 again if you want a CIA installer in Sysnand still. Don't worry, everything that was on your sysNAND is in emuNAND instead. If you don't like this, you can always use Decrypt9WIP or Gateway to restore your NAND.bin, thus recovering all your sysNAND stuff.

If you have Menuhax installed, it will be removed and you will have to reinstall it!

Download TinyFormat Place the .cia in the CIAs folder on your SD card You may use the .3dsx version and run it from the HBL in Sysnand instead; then skip to step 8. Insert your SD card into your 3DS Boot into rxmode SysNAND Don't know how? Hold L when booting rxTools to get into the menu. From there you can select which rxmode you would like to access. Note: 2.5.2 users have to hold X when selecting "Launch rxMode" instead; you can also hold X while launching rxTools, and it will skip the menu entirely and send you to rxMode SysNAND. Once you're in the HOME menu, launch BigBlueMenu, Devmenu_2x, or FBI Install the TinyFormat.cia Press HOME, unwrap the new gift, and launch TinyFormat Follow the instructions to complete the formatting of SysNAND, and thus unlinking your NANDs Turn off your 3DS after the process is finished Reboot your 3DS and complete the Initial 3DS Setup. NANDs are now unlinked! When you are in the 3DS home menu again, launch the eShop application. When you get the message "A system update is available! ...", press Cancel , then press HOME to exit back to the HOME menu. Then press Close to close the eShop. This is to ensure that you won't have any problems installing CIAs while in SysNAND. If you still have any issues with that in the future, see the below spoiler. Else, continue to Section 7!

Spoiler: Do this only if you always get an error when trying to install a CIA while in SysNAND

It should look similar to this:



The folder with the smallest size and random numbers/letters belongs to your sysNAND. It is your sysNAND's ID folder.



Go back to the 3DSCFWKIT folder, go into the Tools folder, and copy the dbs folder to this directory on your SD card:

SysnandIDFolder/RandomNumbersAndLettersFolder/



If there is a "dbs" folder already, you are probably in the wrong ID folder! Do not touch any existing dbs folder or you may lose your data (you can always restore it from the SD card backup we made though).



The dbs folder goes beside the existing "extdata" folder like so:





It is normal that the two files inside the dbs folder are 0KB!



Lastly, boot up your 3DS/2DS (into Sysnand, not Emunand) and go into System Settings —> Data Management —> Nintendo 3DS —> Software. It’ll ask to reset or repair your software management information or sd card, so allow it to do so. On your SD card, open the "Nintendo 3DS" folder.It should look similar to this:The folder with the smallest size and random numbers/letters belongs to your sysNAND.

Section 7 - Installing a CIA installer in Sysnand after Unlinking NANDs!

​

Make sure you still have the BigBlueMenu_inject_with_banner.app file on your SD card. Rename Launcher.dat to E9 Launcher.dat, and rename D9 Launcher.dat to Launcher.dat. We do this so that we can launch Decrypt9 instead of EmuNAND9. You don't have to do this if you are using the Homebrew Launcher to access EmuNAND9 and Decrypt9. Insert your SD card back into your 3DS and launch Decrypt9WIP. Go to SysNAND Options. Choose Health&Safety Inject and enter the button combo. After entering the button combo, press Dpad Down to select BigBlueMenu-with-banner.app, then inject it. When it is done, simply "press START to reboot" your console. Done, the Health & Safety app should now be the BigBlueMenu app (Title Manager) again.

Section 8 - Updating EmuNAND! ​

Backing up your current EmuNAND:

Spoiler: Method 1 using EmuNAND Tool Download EmuNAND Tool - I recommend version 1.0.1

Insert your SD card into your PC.

Open EmuNAND Tool and click "Extract EmuNAND"

Name it however you want - I named mine "9.2 EmuNAND.bin" when I backed up my 9.2 EmuNAND.

Wait for the process to finish - you will know it is finished when the two buttons are clickable again.

Done! Your EmuNAND is now backed up. If you have any of the above mentioned issues after updating EmuNAND, you can restore your backup by clicking "Inject NAND to emuNAND" and selecting the EmuNAND bin file!

Spoiler: Method 2 using 3DS Multi EmuNAND Creator Download 3DS Multi EmuNAND Creator

Insert your SD card into your PC.

Open 3DS Multi EmuNAND Creator with Administrator privileges and click "Extract NAND"

Name the EmuNAND backup however you want - I named mine "9.2 EmuNAND.bin" when I backed up my 9.2 EmuNAND.

Wait for the process to finish - you will know it is finished when the green bar reaches the very right and the "Operation successfully completed!" message pops up. Just press OK and close 3DS Multi EmuNAND Creator.

Done! Your EmuNAND is now backed up. If you have any of the above mentioned issues after updating EmuNAND, you can restore your backup by clicking "Inject EmuNAND" and selecting the EmuNAND backup!

How to properly update emuNAND on an O3DS or 2DS:

Boot into Emunand, and launch System Settings.

Make sure it says RX-E or RX3D in front of the version number to be sure that you are in EmuNAND. If it says RX-S or Ver. , you are in SysNAND, and updating SysNAND will leave you unable to continue!

or in front of the version number to be sure that you are in EmuNAND. If it says or , you are in SysNAND, and updating SysNAND will leave you unable to continue! Do NOT exit System Settings at this point or you will be kicked back to sysNAND!

exit System Settings at this point or you will be kicked back to sysNAND! Press Other Settings

Scroll to the right until you see System Update

Press System Update and accept

When it is done, your 3DS will reboot into sysNAND If you have Menuhax, your 3DS will reboot and launch Menuhax instead. That is not a problem.

When you launch rxTools and boot into EmuNAND, you will see that it is now updated to the latest version

If you have any issues launching EmuNAND after updating it, you can restore your EmuNAND backup (if you made one). See the last step in "Backing up your current EmuNAND". After restoring your EmuNAND backup, you can try updating it again. If it still doesn't work, go to the F.A.Q./Troubleshooting section to see solutions. If the update STILL doesn't work, see the below spoiler for an alternate method to update your EmuNAND.



Spoiler: Alternate method to update EmuNAND! Download 3DNUS and launch it Type in the latest firmware version in the Title ID box, without the letter at the end. Ex: 10.6.0-31 Type your region (ex: EUR) in the Version box Leave Pack as .CIA checked Click Download Place all the CIAs that it downloads in a single folder on your SD card Insert your SD card into your 3DS and go into EmuNAND Launch BigBlueMenu Navigate to the inside of that folder where all the CIAs are, then press L + R + A to import/install all the cias Power down your 3DS normally when it is done Your EmuNAND should be on the latest firmware when you access it again

Section 9 - Let's recap. ​

We set up rxTools for accessing via the browser or the Homebrew Launcher - this is not the only way to access rxTools, and it is actually the most inefficient way to do it. Read the Menuhax (recommended) or MSET section to learn more!

We made a NAND backup - this is important in case you ever brick your 3DS.



We injected/installed BigBlueMenu to SysNAND and used it to install Devmenu_2x and the patched AGB_FIRM - this is beneficial because: You can use it to install GBA and DSi games You will always have a CIA installer when you update your EmuNAND.

We created EmuNAND. EmuNAND provides a layer of protection, which helps prevent our SysNAND from being updated or bricked.

We unlinked our NANDs in order to avoid certain issues.

We have updated EmuNAND to the latest version - this allows the highest game compatibility, and eShop access.

How to install Games, Updates, Patches, DLC, Homebrew, etc. using BigBlueMenu / Title Manager / BBM / Devmenu ​

Download any .cia file. Don't ask where to get them. There is a certain iso site for 3DS games that you can find on Google.

Highlight the .cia and press A.

Press A once more to confirm the installation.

Wait for it to finish.

If you want to delete the .cia file after installation (since it isn't needed anymore once installed), highlight the .cia and press X, then A to confirm.

Press HOME and you should get a notification that you have a new app. This only happens if it's a new game, app, or homebrew that you installed. There is no notification if you just installed DLC, a game update, or a System App.

Unwrap the gift and enjoy!

DSi/GBA/NES/etc. support ​

Have a DS flashcard? ​

Launch RxMode Sysnand and open FBI or Devmenu_2x.

If using FBI: Press L to change Destination to NAND.

Navigate to the CIAs folder.

folder. Select DSFlashcardWhitelistPatch.cia and press A to install it.

If using FBI: Choose to overwrite the title when it prompts you.

Once done, exit the CIA installer.

If your DS flashcard still doesn't work, then it will probably never work on your 3DS.

You should be able to use your DS flashcard in any mode (Sysnand, RxMode, Devmode/Pasta Mode), but exiting the card will bring you back to regular sysnand.

Running a DS flashcard will remove your MSET exploit if you have one (see the next section).

You can use a DS flashcard to easily install the MSET exploit (see the MSET section).

Launching rxTools at Boot - Menuhax! ​

Set a random theme on your 3DS, then change it back to the default theme. Make sure your WiFi is on and you are connected to the Internet!! Launch rxmode SysNAND (Hold L when booting rxTools to access it) Open BigBlueMenu (or any other CIA installer) If you already have access to the Homebrew Launcher, skip to step 9!! Install hblauncher_loader.cia (it's in the CIAs folder) Exit to the HOME menu; there will be a new gift. It is the Homebrew Launcher cia. Launch the Homebrew Launcher via the Homebrew Launcher cia you just installed in SysNAND.

[*]If you can access the HBL through any other *hax entrypoint in regular or rxmode sysnand, such as Cubic Ninja, Ironfall, Ocarina of Time, etc., then I urge you to do so. They usually work better than Browserhax. [*]People following this guide that don't have CFW can use Browserhax instead! Note: If your browser crashes after touching the slider, turn off your 3DS then turn it on and try it again. According to @chickendude , this has worked for him every time.[*]If you can access the HBL through any other *hax entrypoint in regular or rxmode sysnand, such as Cubic Ninja, Ironfall, Ocarina of Time, etc., then I urge you to do so. They usually work better than Browserhax. Click to expand... In the Homebrew Launcher, run the menuhax_manager installer and install menuhax. After all that, test if menuhax boots you into the homebrew menu at cold boot. Just turn off your 3DS and turn it back on, and don't press any buttons. On your SD card, look for the file which name starts with "ropbinpayload". Open it with HxD (included in the 3DSCFWKIT/Tools folder). Press CTRL+F, change Type to "Text string", and search for boot.3dsx. There will be two results. Change both to auto.3dsx and save the file.



When you turn on your 3DS, you should see the bottom screen flash multiple colors, followed by the rxTools splash screen.

The Menuhax button config is as follows:

Menuhax loads if no buttons are held while the 3DS boots.

Menuhax does not load if your hold the R button while the 3DS boots. Additionally:

If you hold L while the 3DS boots, you will boot into the rxTools menu.

If you hold SELECT while the 3DS boots, you will boot into the CTRBootManager menu. Some precautions:

Changing your theme in SysNAND will remove Menuhax; that is, you would have to reinstall Menuhax again.

Menuhax; that is, you would have to reinstall Menuhax again. If your NANDs are still linked, Menuhax would also be installed in EmuNAND. This means you will get a black screen every time you attempt to load EmuNAND. To solve this, you can either: Hold any button when launching EmuNAND to disable it from loading; you will have to do this every time . Unlink your NANDs (Section 6), launch EmuNAND while holding any button to disable Menuhax from loading, then change the EmuNAND theme to remove it completely from EmuNAND without removing it from SysNAND.

Launching rxTools through the System Settings app - MSET! ​

Understanding FBI

Spoiler

EASIEST METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download (or open the 3DSCFWKIT/MSET Installers/ folder) and put the rxinstaller.nds file on your DS flashcard's SD card. Now run it with your DS flashcard and select "rxtools 4.x".

If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download (or open the 3DSCFWKIT/MSET Installers/ folder) and put the rxinstaller.nds file on your DS flashcard's SD card. Now run it with your DS flashcard and select "rxtools 4.x". To install MSET with FBI, simply launch rxmode sysnand, launch FBI, and press SELECT. Now, select "rxtools3.x 4.x". MSET should now be installed.

To install MSET with the internet browser, simply put the rxinstaller.bin on your SD card root. Then launch the browser and go to http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin . It should freeze and crash, and send you back to the home menu. MSET should now be set up. To launch rxTools via MSET, just turn on your 3ds, go to System Settings-> Other Settings-> Profile-> Nintendo DS Profile, and rxTools should boot. Use one of the following methods:To launch rxTools via MSET, just turn on your 3ds, go to System Settings-> Other Settings-> Profile-> Nintendo DS Profile, and rxTools should boot.

Spoiler If you don't have a DS flashcard: grab the rxinstaller.bin for rxTools from the "mset" folder (or the 3DSCFWKIT/MSET Installers folder) and put it on your sd card root. Go HERE (click the "CIA Format DLC's, Themes & Updates" link. Name of the thread is "[MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions)") Download one of the following cias according to your region:

MSET-EUR-4.0 0004001000022000

MSET-JPN-4.0 0004001000020000 Place the .cia anywhere in your sd card. Launch RXMODE SysNAND (Hold L when rxTools is booting to get into the menu first; if using rxTools 2.5.2, hold X instead) Launch Devmenu_2x or FBI

For FBI, destination should be set to NAND. Click to expand... Install the .cia you downloaded above and then exit to the HOME menu.

EASY METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download (or open the 3DSCFWKIT/MSET Installers folder) and put the rxinstaller.nds file on your DS flashcard's SD card. Now run it with your DS flashcard and select "rxtools 4.X DG". Then skip to step 11! Note: the "DG" beside the system version number means "downgraded". Open the 3DS browser, and enter this URL: http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin Wait for a bit (it should crash and send you back to the home menu). If it doesn't crash after a minute, press HOME and it should crash. If the next step (8) doesn't work, try clearing your cache and history before entering one of the above links. Now you can launch rxtools by going to System Settings-> Other Settings-> Profile-> Nintendo DS Profile

How to Update your 3DS/2DS to 9.0 or 9.2 ​

Warning: This can brick your 3DS if done incorrectly! Be sure that you follow the instructions carefully!

BigBlueMenu installed in sysnand ( Section 4 if you don't have Gateway or Ninjhax) OR any other cia installer on Sysnand.

if you don't have Gateway or Ninjhax) any other cia installer on Sysnand. A rxTools 3.0 nightly (preferably the one linked in Section 1 ) Also works on rxTools 2.5.2 (for those that can't launch 3.0)

)

See AidanLumina's tweet here and click Files for downgrade/manual update.

Download one of the O3DS 9.2 update packs (it has to match your region, see the picture below!) Spoiler: Picture Once downloaded, open the O3DS 9.2 update pack and find the "updates" folder; place it on your SD card. There should be many cia files in that folder. Example: SD:/updates/0004013000008003.cia Download Sysupdater Open the Sysupdater archive, find sysUpdater.cia and place it on your SD card inside the CIAs folder. Insert your SD card in your 3DS Hold L while launching rxTools to get into the rxTools menu. If using rxTools 2.5.2, hold R instead. Press DPAD RIGHT until you highlight ADVANCED OPTIONS, then press A. Skip this step if you are using rxTools 2.5.2 Go down to DEVMODE or PASTA MODE and press A After a few seconds, you should now be in sysnand; firmware spoofing is disabled but cias can still be launched in this mode. Launch your SysNAND's CIA installer Install sysUpdater.cia (Destination: SD if using FBI) Once installed, press HOME to see sysUpdater wrapped as a gift; unwrap it. Launch sysUpdater sysUpdater will ask you if you are sure you want to go ahead with the update; choose to accept it. It will also tell you that you shouldn't be in Gateway mode, or have firmware spoofing. Do not worry about this, DEVMODE / PASTA MODE has no firmware spoofing, so sysUpdater will work as intended. Just be absolutely sure you are in DEVMODE / PASTA MODE (line 10), not RXMODE SYSNAND! Wait for sysUpdater to finish. When it is done, your 3DS will reboot into 9.0 or 9.2 firmware! You can now follow the steps to use Menuhax if you'd like.

Spoiler: If you can't find the 9.2 pack in AidanLumina's MEGA folder Click HERE Click the CIA Format DLC's, Themes & Updates [Archive] result Click View Full Version : CIA Format DLC's, Themes & Updates at the top of the page Find the thread titled [MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions) Scroll down to the section titled Updates Download either the 9.2 modified update pack for your region, or a 9.0 or 9.2 Full Update Pack for you region

How to Update to a Newer rxTools Version ​

Run cdn_firm.py in the "Tools" folder. It will generate a firm folder in the same folder that cdn_firm.py is in. The firm folder must go into the rxTools folder like so: SD:/rxtools/firm

Removing files you don't need from your SD card!

​

The Nintendo 3DS folder Contains all your CIA/eShop games, saves, DLC, patches, themes, etc.

folder The rxTools folder Required to launch rxTools.

folder The slot0x25KeyX.bin file* Only required for users below 7.x SysNAND firmware.

file*

The 3ds folder Contains all Homebrew Launcher apps.

folder boot.3dsx Required to actually launch the HBL.



The same as the Homebrew Launcher, plus:

menuhax_imagedisplay.bin Shows a custom image when the 3DS boots up. The one included in the CFW Kit is just a black image. You can change it through the Menuhax Installer.

menuhax_padcfg.bin This is the button configuration file that Menuhax reads. The one included in the CFW Kit tells Menuhax to launch automatically unless you are holding the R button while your 3DS boots.

The ropbinpayload_menuhax bin file. This tells Menuhax which .3dsx file it will launch on boot. If you followed the Menuhax section in the guide, you should know that we edited this file to point to auto.3dsx, which is the .3dsx for CTRBootManager. Speaking of that...

bin file.

auto.3dsx This is the .3dsx of CTRBootManager. It is also the file that we configured Menuhax to load on boot (instead of boot.3dsx, remember?)

boot.cfg This is the configuration file for CTRBootManager. It tells CTRBM what CFW or Homebrew application to autoboot after Menuhax loads CTRBootManager (a bit confusing, I know ). We currently have it set to autoboot rxTools. But if you hold SELECT while your 3DS boots, you will be directed to the CTRBootManager menu, where you can choose other CFW or Homebrew that you want to boot.



How to move Games, Saves, Themes, and Emunand to a new SD card ​

Spoiler: Method 1 using EmuNAND Tool Get Emunand Tool (latest version, or version 1.0.1 if you get an error in step 12) Insert your old SD card in your PC Open Emunand Tool and select "Extract EmuNAND" Save it somewhere on your PC (as [EmuNAND firmware version] emunand.bin if you want) Backup all your SD card files to your PC Eject your old SD card Put EmuNAND9's launcher.dat on your new SD card Launch EmuNAND9 using the web browser in Sysnand (URL: go.gateway-3ds.com) Once in EmuNAND9, navigate to Complete EmuNAND Setup. Ignore the starter.bin warning and follow the instructions. Wait for the EmuNAND creation process to finish. Turn off your 3DS Insert your new SD card in your PC Open Emunand Tool and select "Inject NAND to emuNAND" Select the emunand.bin you made in step 4 and press OK Close Emunand Tool when done - you will know it is done when the buttons are clickable again Delete all the files on your new SD card Put the SD card files from your backup (from step 5) on your new SD card Done, emunand and data (saves, games, etc.) have been transferred to your new SD card!

Spoiler: Method 2 using 3DS Multi EmuNAND Creator Get 3DS Multi EmuNAND Creator Insert your old SD card in your PC Open 3DS Multi EmuNAND Creator with Administrator privileges and select "Extract NAND" Save the EmuNAND backup somewhere on your PC (as [EmuNAND firmware version] emunand.bin if you want) Wait for the "Operation successfully completed!" message to pop up, then click OK. You now have your EmuNAND backup from your old SD card. Backup all your SD card files to your PC Close 3DS Multi EmuNAND Creator and eject your old SD card Insert your new SD card in your PC Open 3DS Multi EmuNAND Creator again Under the Format EmuNAND section, make sure that your new SD card is selected, then click "Start Format" Select the emunand bin file you made in step 4 and click Open Click Yes at the warning to start the process Wait for the green bar to reach the end and the "Operation successfully completed!" message to pop up, then press OK Close 3DS Multi EmuNAND Creator Put the SD card files from your old sd card backup (from step 5) on your new SD card Done, emunand and data (saves, games, etc.) have been transferred to your new SD card!

F.A.Q./Troubleshooting

​





Spoiler 1. Backup your emuNAND.

2. Backup all emuNAND files (ticket.db etc.) with rxTools.

3. Backup the content of your SD card.

4. Format emuNAND.

5. Recover your SD card content and boot rxTools in emuNAND.

6. Update to 10.3.0-28X and boot into emuNAND again.

7. Go to system settings and to NNID at the top; follow instructions.

8. Boot emuNAND and start the eShop; simply restart the 3DS if it keeps looping after the password input.

9. Once in the eShop, close it and shut down.

10. Recover your whole SD card once more. *

11. Inject emuNAND backup.

12. Inject all emuNAND file backups.

13. Start the eShop in emuNAND and it should refresh your software.

14. And now you should have emuNAND eShop access without any loss ofStreetPass/Save/Friend/etc. data.

If your EmuNAND doesn't load after updating it (thanks to



Spoiler



1. Go in your sd card, in the "Nintendo 3DS" folder, and browse through both <random character> folders to find the "extdata" folder. Find any folder that is named either "000002cc", "000002cd", or "000002ce".

If any of those folders are there, delete them. This will reset your theme and ensure that themehax/menuhax is not present on your sd card. Even if you never used Menuhax or you don't use it anymore, try this solution.



2. If you have a black screen AFTER launching your EmuNAND cfw, try reformatting your SD card from your PC and then from your 3DS. Then restore the SD card backup you made in Section 5.

If that doesn't work, you may have to restart the tutorial as well.



3. If you don't want to do any of the above, rxTools 2.6 Three different solutions. Try each of these in the way I ordered them.1. Go in your sd card, in the "Nintendo 3DS" folder, and browse through both folders to find the "extdata" folder. Find any folder that is named either "000002cc", "000002cd", or "000002ce".If any of those folders are there, delete them. This will reset your theme and ensure that themehax/menuhax is not present on your sd card. Even if you never used Menuhax or you don't use it anymore, try this solution.2. If you have a black screen AFTER launching your EmuNAND cfw, try reformatting your SD card from your PC and then from your 3DS. Then restore the SD card backup you made in Section 5.If that doesn't work, you may have to restart the tutorial as well.3. If you don't want to do any of the above, rxTools 2.6 reportedly loads your updated EmuNAND just fine. You can download it at rxtools.net If you get the "022-2634" when trying to access the eShop on the latest EmuNAND, try this (thanks to @Nestar ):If your EmuNAND doesn't load after updating it (thanks to @Lord_Possum and @secousa ):

always

Spoiler If you have a smaller, spare SD card, place your "Nintendo 3DS" folder in it and create a new EmuNAND on it using either EmuNAND9 or 3DS Multi EmuNAND Creator (using your NAND.bin backup from Section 2). Then transfer your EmuNAND to your bigger card using the instructions in the section "How to move Games, Saves, Themes, and Emunand to a new SD card".
