This Multi-Guide provides instruction for the following:

Back up your NAND,
Backup your system information,
Restore your NAND,
Make exFAT work on lower system versions
​

Please read and follow the following disclaimer before attempting to follow this guide:

Only use the files attached, I update these when needed to ensure that they are functioning. Failure to use the attached files may result in issues.

I take no responsibility for issues you may have as a result of the use of the files or instructions contained within these guides. You execute this/these guide(s) at your own risk. I'm happy to help with any questions. Please review the comments and answers on this thread as well. I try to provide assistance when requested.

Before any modification of your system, I recommend you back-up your NAND (to make yourself a clean back-up and/or a virgin NAND). Don’t use Auto RCM until after you complete your back-up.​

To follow the below guides, you will need the following:

• A micro SD card formatted to exFAT or FAT32 with at least 32 GB of free space
• All files attached at end of this guide, extracted to your PC
• Fully charged Switch (or the ability to keep the Switch plugged into a power source during the restore process)
• USB to USB-c cable (short is better)

This guide assumes you have some method of entering into RCM. (e.g. RCM jig installed or shorting pins 1+10 on the Joy-Con rail.)
You may also run the "Hekate.bin" from your own dongle or method from the
"Payloads to be used with tegra.zip" if you do not wish to use TegraGUI​

For Fat32 users only >>Join RawNand Parts Mini Guide​

Spoiler: Join or Merge RawNand Parts guide into 1 file

Download this first click here > >joiner_scripts_for_windows_linux_macos.zip
to combine the 15 parts or 30 parts of rawnand00.bin etc into 1 rawnand.bin file
Place the correct script into the folder where you have the 15 or 30 parts backed up.
example
If you have 15 parts rawnand files use the join_15_2GBparts_linux_macosx.bat For Mac
or for windows use the join_15_2GBparts_windows.bat
Simply move the desired script that matches your system windows or mac 15 or 30 parts to the folder where you have your rawnand in parts 15 or 30 double click the bat file and it will merge/join those into one file called rawnand.bin

Backup Guide ​

Spoiler: Click show to view Backup Guide

In order to run the "Hekate.bin", you first need to setup and install a payload sender and the apx driver. I have provided an application (TegraRcmGUI) in the zip files at the end of this post.

You may also run the "Hekate.bin" from your own dongle or method from the "Payloads to be used with tegra.zip" if you do not wish to use TegraGUI



Steps for this are as follows:

1. Extract TegraRcmGUI_v#.#_Installer.zip on your PC and install
   
   
2. In TegraRcmGUI, select the “Settings” tab and then click “Install Driver”
   
   
   
   
   
   
3. Place the contents of “SDFILES PART 1.zip” and “SDFILES PART 2.zip” and also “SDFILES PART 3.zip” onto the root of the SD card
   - Remember to format your 32 GB SD card to exFAT or FAT32 first
   
   
4. Place the SD card into the Switch
   
   
5. Put your Switch into RCM by holding volume up + power
   - Click this link for instructions for entering >RCM<
   
   
6. With TegraRcmGUI open, connect the Switch to the PC
   - Before injecting, the Switch Icon will change to green and indicate “RCM OK” if Switch was connected correctly in RCM mode
   
   
   
7. In TegraRcmGUI: Payload tab, navigate to the location of the hekate.bin on your PC and Inject payload
   (the hekate.bin is in the payloads to be used with tegra.zip)
   
   - The Switch Icon in TegraRcmGUI will change to orange hourglass during injection
   - If payload is sent correctly, Switch Icon in TegraRcmGUI will change to green checkmark
   - If the payload is not sent, try using a different (shorter) cable and repeat from step 5.
   
   
8. Switch will automatically boot into Hekate bootloader (steps 9-24 take place on the Switch)
   
   
9. From the hekate main menu, select “Console Info”
   
   
   
   
   
   
10. Select “Ipatches & bootrom info” (this isn’t in the screenshot above but should be in the Hekate Console info menu.)
    
    
11. Follow the instructions to dump to SD card
    
    
12. Return to Console info menu
    
    
13. Repeat steps 10-12 for “Print fuse info”, “Print kfuse info” and “Print TSEC keys”
    
    
14. Return to Hekate main menu (by selecting “Back” at the top)
    
    
15. From the hekate main menu, Select “Tools”
    
    
    
    
    
    
16. Select “Dump package1/2” and allow this to run
    
    
17. When complete, return to Tools menu
    
    
18. “Select “Backup”
    
    
    
    
    
    
19. Select “Backup eMMC BOOT0/1” and allow this to run
    
    
20. When complete, return to “Backup options” menu (by selecting “Back” at the top)
    
    
21. Repeat steps 19 & 20, selecting “Backup eMMC RAW GPP”, “Backup eMMC SYS” & “Backup eMMC USER” instead of “Backup eMMC BOOT0/1”
    - These may take some time so be patient. The result will be a
    - dump of Full NAND Minus the boot0/1
    
    
    - (I RECOMMEND YOU BACKUP EMMC SYS , YOU WILL NEED A EXTRA 2.61GB ON SD CARD FOR THIS..
    Used so you can recover switch in case of bad rawnand)
    ANOTHER COPY OF YOUR SYS FILES THE SAME IN YOUR RAWNAND.BIN Basically
    
    
    - (Backing up EMMC USER is Your Choice as it requires 26gb Extra)
    Used to backup your User files saves games etc
    
    
    emmc user and emmc sys are in your rawnand.bin > (eMMC RAW GPP)
    
    
    
    
22. Return to Hekate main menu (by selecting “Back” at the top)
    
    
    
23. From the hekate main menu, Select “Launch”
    
    
    
    
    
    
24. Select “BisKeyDump" from the Tools section
    
    
25. Your keys will display on the screen. Follow the onscreen instructions to dump keys to SD card
    - Resulting file, on the root of the SD card, will be named device.keys
    - Rename to “biskeys.txt” if you wish.
    
    
26. With TegraRcmGUI open, connect the Switch to the PC
    
    
27. In TegraRcmGUI: Payload tab, navigate to the location of the Lockpick_RCM.bin on your PC and Inject payload... (Lockpick_RCM.bin is in the payloads to be used with tegra.zip)
    - You should now be presented with a freaking rainbow
    - It will automatically dump your keys to your SD card to the "switch folder" the file will be named "prod.keys"
    
    
28. Press the power button on your switch.
    - Once powered off remove your SD card and put it into your pc.
    -You can now close Tegra and remove USB cable from switch to pc, if still connected.

Ensure you have a complete set of dump files:

Dump all the console info using the payload I included hekate.bin
(the hekate.bin is in the payloads to be used with tegra.zip)

1. From the hekate main menu, select “Console Info”
   
   
   
   - Console Info -> Print fuse info -> Press power button
   - Console Info -> Print kfuse info -> Press power button
   - Console Info -> Print TSEC keys -> Press power button
   
   
2. From the hekate main menu, Select “Tools"
   
   
   - Tools -> Backup -> Backup eMMC BOOT0/1
   - Tools -> Dump package1/2
   
3. Ensure all of the following files are on your SD card:

4. In the backup folder on the SD card, inside the letter and number folder, open folder dumps. Confirm the following files are present:
   
   
   - fuses.bin
   - kfuses.bin
   - tsec_key.bin
   
   
   If you’re missing one of the above .bin files, follow the Console Info instructions (above) to dump them again.
5. In the pckg1 and pckg 2 folders on the SD card, confirm the following files are present:
   
   
   pckg1 folder
   - nxloader.bin
   - pkg1_decr.bin
   - secmon.bin
   - warmboot.bin
   
   pckg2 folder
   - ini1.bin
   - kernel.bin
   - pkg2_decr.bin
   
   
   If you’re missing one of the above .bin files, follow the Tools -> Dump package 1/2 instructions (above) to dump them again.
6. On the SD Root, confirm the following files are present:
   
   
   - Boot0
   - Boot1
   
7. In the backup random number letters folder, confirm the above files are present as well.
   
   
   
   If you’re missing one of the above files, follow the Tools -> backup emmc BOOT0/1 instructions (above) to dump them again.
   
   If they are missing from one location or the other, they can be copied to the location where they are missing.

Try the Goldleaf.nro again

Before you continue

It has come to my attention that some windows 10 operating systems with builds 1507/1511/1607 will experience an issue transferring nand or switch system files from PC to your SD card or Switch. This issue results in missing bits in the copies of the archive bits, needed for the switch to operate correctly or restore of nand to work.

Our member here @Draxzelex was nice to point this out , so I thought I would add it to the guide.

If you’re on one of the affected versions of Windows 10, before transferring your files, it is recommended to use a third party application called Total commander to transfer the backups to your SD card or even when you’re moving the backup folders on PC

To check your windows 10 version:

Go to windows search by clicking the windows key (start)

Search for ‘about your PC’ in the search bar, and select ‘About your PC’ in the search results

On the right-hand side scroll down to Windows Specifications

In this section, you will see your build version

If you are above build 1607 you can ignore this information in blue.
If you are not above version 1607 then either please use Windows Update to update your build or use Total commander to move your backups around your PC or to SD card

Instead of using Total commander, you could try a method of using a compression zip/rar program like WinRAR to archive or compress the backup folder on your SD before you even think about transferring to PC, and when you go to move backup back to SD card transfer your zip or RAR to SD then extract it from there

(Not tested )

You may Continue


29. On your PC make a folder where you're going to place your backup switch nand and files



30. If you used lockpick to backup your prod.keys then Open your SD card on your PC and copy the prod.keys from the switch folder on the SD card to the folder.



31. Copy the entire backup folder from SD card to your backup folder on PC.



32. Please zip or rar the backup folder once you have transferred it on your PC
this will also save space.



Also, save the biskey.txt and prod.keys You made earlier to your backup folder
Once you backed up to your PC

And that's it.


I hope this may of helped you all or i just wasted hours of my life here


You can skip the guide below if your only backing up your nand and keys

Restore Nand Guide​

I take no responsibility for issues you may have or if your system fails to boot after restoring your NAND.
You do this at your own risk!

Please make sure to read the blue text in my Backup guide above when you made your backup

To follow the below guide, you will need the following:

Make sure your battery is charged (at least enough to complete the restore process) or keep the switch plugged into a power source (USB cable should be fine)

Spoiler: Click show to view Restore Nand Guide

Restoring your nand.....

Providing you have followed my guide above to back-up your NAND, you should have the 3 required files in your backup folder
(Plus some other files we won't be using for your restore)

- boot 0 ​

- boot 1​

- rawnand.bin
​

If you do not have these files please do not continue

1. From your number and letters folder inside the backup folder on pc, copy the below files to the restore folder on your SD card
   
   
   - Boot 0
   - Boot 1
   - rawnand.bin
   
   
   Example on sd card
   inside The folder on SD card Backup>numberletter folder>restore folder <....place files here...
2. Place the SD card into the Switch
   
   
3. Put your Switch into Rcm Mode
   
   
4. Boot into the hekate bootloader *Hekate.bin* By using tegrarcmsmashGUI
   
   
   
   
   
5. From the bootloader hekate main screen, select tools option with the volume +/- buttons and press power button to select
   
   
   
   
   
6. In the tools section, Select Restore
   
   
   
   
   
   
   
   
7. In the restore options screen, select “Restore eMMC BOOT 0/1”
   - You will be warned and asked if you are sure. To continue, press the power button and wait for the process to finish.
   - Once finished press any key to go back (do not power off at any time)
   
   
   
   
   
   
   
   
8. Still in the restore options screen, select “Restore eMMC RAW GPP”
   - You will be warned and asked if you are sure. To continue, press the power button and wait for the process to finish. This will take some time.
   - Once finished press any key to go back (do not power off at any time)
   
   
   
   
   
   
   
   Now assuming all the processes went smoothly and you got no errors you should now be restored!
9. Go back to the Hekate main menu by selecting back
   
   
   
   
   
   
   
   
10. On the main menu select power off.
    
    
    
    
    
11. Reboot your switch as normal with the power button

If all went well, you should now see the Nintendo logo and should boot back into the main OS of the switch.


Well done you successfully restored your NAND!!

Did you sh*t your pants ???


Again I take no responsibility For backing up and or restoring your NAND, this is a dangerous process and you do it at your own risk.

Exfat Update Guide For
Lower System Versions​

Spoiler: Click here to view exfat update guide

At this time I have not made the exFAT guide myself so until I do I thought I’d link to another exFAT guide,
Please like his thread if it helps you and mine if you like the information I’ve provided

Method 1 (Not as easy but doable)
Method 1 Link
Method 2 (A lot easier)
Method 2 Link


Info taken from Method 2


Q: I just want to install exFAT on the current firmware version I already have. Can I do this using ChoiDujourNX?


A: Absolutely, just place a folder containing the exFAT version of the firmware you are currently running and choose it inside ChoiDujourNX. It will only install the required couple of packages needed for exFAT, and you can even disable the AutoRCM option (if you are sure the firmware you are installing is the same burned fuse count as the one you are currently running).

Ok here i have put together a non fancy guide to get you backed up and get your keys.txt and your console keys

The information i will provide is parts of guides already here on the gba temp i take no credit for this.


Preparation: Files attached in zip format at end of this guide Extract these first to your pc

You will need a micro sd card formatted to exfat with atleast 32 gb Of free space to follow this guide and guides.
You will also need this Special hekate payload for this guide as you can dump all the console info
You Will also need Biskeydump payload to get your biskeys
You will also need kezplez-nx.nro and kezplez-nx.nacp, to Dump your keys.txt to sd card

These Guides I have used Which will help you

kezplez homebrew Guide to get all your Keys (Keys.txt)
https://gbatemp.net/threads/kezplez-nx-v1-0-get-all-your-keys-straight-from-your-switch.510846/



Ok lets try keep this simple

Firstly
you will want to Follow the Tegrasmash guide to set up your payload sender
and install your apx driver, and then put your Switch into Rcm Mode by holding
volume up + power with your rcm jig installed or shorting pins 1+10 on the joycon rail..

Secondly
Drag and drop the files in the sdfiles.zip attached, onto the root of the sd card
Now place the sd card into the switch

Thirdly
You Send the attached ipl.bin to your switch with Tegra Gui
Once your switch boots into hekate bootloader
Select Console Info

then select print fuse info , kfuse info , Tsec keys, and battery info if you wish Individually
When you select these options it will give you the option to dump each of these with the power button.. so go ahead and do that.Once you dump them,Go back

Then you Select Tools Option In hekate

and Dump package1/2 once completed select back

Then select Backup option

Then Select Backup Emmc Boot 0/1 Once this is backed up
Press any button volume or power
Then select Backup Emmc Sys Once this is backed up
Press any button volume or power
Then Select Backup emmc Raw Gpp
(Now this will take some time to complete be patient This will dump Full Nand Minus the boot0/1)
Once this is backed up
Press any button volume or power

Ok so thats your nand backed up.... And info placed in the backup folder in your sd card

Now for your keys

Go back to hekates main menu

Ok now on pc Load the biskeydump.bin attached into the tegra gui select auto inject

Then back on your switch on the hekate menu with the usb cable still connected to pc
Select the option reboot rcm this should now load into biskey Loader
On the screen is your biskeys and other info take note of these or use a qr scanner app on your mobile/Cell phone,to scan the Qr code Some Qr scanner apps have a feature to send the scanned file in text format to a email address do this and open your email and save the info to a text file called biskeys.txt

Ok

So now you will need to restart your switch and load back into the hekate bootloader menu to do this load the ipl.bin in the tegra gui, hold the power down and volume up then inject the payload.

Once your back into the Hekate menu you will want to go to Launch or launch firmware

Then select CFW to load custom firmware,

After this Select album twice on switch main menu Once loaded, you should load into Homebrew menu,
from here select kezplez and launch it... you should now be presented with a freaking rainbow
Press A on joycon to begin to dump your keys.txt to your sd card. You will be notified once this is completed



Last but not least
Hold down the power button on you switch then select power off.
Once powered off remove your sd card and put it into your pc.
You can now close tegra and remove usb cable from switch to pc.


Before you continue

It has come to my attention that some windows 10 operating systems with
builds 1507/1511/1607 will suffer a issue were when your transferring nand or switch system files from pc to say sd card or switch Will not copy Archive bits correctly which is needed for the switch to operate correctly,or restore of nand to work ..Our member here @Draxzelex Was nice to point this out so i thought i would add it to the guide before transferring your files, he recommends using a third party Application Called Total commander Found here https://www.ghisler.com/ To transfer the backups to sd or when your moving the backup folders on pc, If your on one of those affected versions of windows 10

To check your windows 10 version
Goto windows search by clicking the windows key (start)
and type.... about your pc in your search bar, select about your pc in the search results and on the right hand side scroll down to Windows specifactions there you will see your build version if you are above build 1607 then ignore the information in blue.
If you are not above version 1607 then either please use windows update to update your build or use total commander to move your backups around your pc or to sd

Or to play it safe you could try a method of Using a compression prgoram zip rar program like winrar to archive or compress the backup folder on your sd before you even think about transfering to pc,, and when you go to move backup back to sd card transfer your zip or rar to sd then extract it from there (Not tested )

You may Continue

On your pc make a folder were your going to place your backup switch nand and files
Open your sd card on your pc and copy the keys.txt from root of card to your folder then copy the entire backup folder from sd card to your backup folder on pc.

Please zip/rar the backup folder once you have it on your pc
this will also save space

Also save the biskey.txt You made earlier to your backup folder

Once you backed up to your pc
Now erase your sd card so theres no conflicts with other files u may use or other guides
And thats it..


Sorry about the mess of the guide maybe someone could clear it up for me
I hope this may of helped you all or i just wasted hours of my life here

Thank you to all the Hosts of the threads/Guides and creators of the files i used your doing awesome work and i appreciate it...

Certain builds of Windows 10 don't transfer the archive bits properly which is needed for the way Horizon operates (chicken and egg problem here). Forgot which ones they were, but if you use a 3rd party program like Total Commander, the files will transfer over without any issues.

Btw, is there anyway to tell if the NAND is correctly copied or not like by comparing bytes with NAND of other users (that is, if they are of some same size ) etc?

 

[Canna]

Btw, is there anyway to tell if the NAND is correctly copied or not like by comparing bytes with NAND of other users (that is, if they are of some same size ) etc?

Im not sure about that... But does it not verify and tell you its verified after the restore process ???
Sure it does right ?

If it was not correctly copied over with the above issue then it wont load

 

[KJ1]

To be honest, I have not tried that yet. I have to backup my NAND, that's why I am asking questions.
So, where does it tell you its verified? Do you mean it tells that after it has backed up whole NAND?

Also, where it won't load?

When you using Hekate V3.1+ it has a verification process while it dumps the NAND, its a green bar. The verification slows down the process so there is a way to toggle it so the verification is done less efficiently to speed up the process. But I don't see a reason to do this as the NAND dumping process still takes a long time.

Hes talking about the restore to the chip not from it buddy or both

You can verify when you dump, not sure about when you restore.

Make sure to Use the files i have uploaded Especially
kezplez-nx.nro and kezplez-nx.nacp
and ipl.bin as your bootloader (As this bin lets u dump tsec which is probally your problem

Yes make sure you dump all the console info use the payload i included ipl.bin

In Bootloader Goto Console Info

• Console Info -> Print fuse info -> Press power button
• Console Info -> Print kfuse info -> Press power button
• Console Info -> Print TSEC keys -> Press power button

Be sure it dumps

Then Goto tools in bootloader menu

• Tools -> Backup -> Backup eMMC BOOT0/1
• Tools -> Dump package1/2

MAKE SURE
kezplez-nx.nro and kezplez-nx.nacp is in

/switch/kezplez-nx on your sd card

Checking to make sure you have the files on your sd card

In the backup folder on sd open folder dumps
in this folder should be
fuses.bin
kfuses.bin
tsec_key.bin

If your missing one then dump it with console info again

On sd also should be

pckg1 and pckg 2 folders which is dumped from the tools section on bootloader
called dump package 1

pckg1 folder on sd

in there should be
nxloader.bin
pkg1_decr.bin
secmon.bin
warmboot.bin


pckg2 folder on sd

ini1.bin
kernel.bin
pkg2_decr.bin

And also on sd root

should be
Boot0
Boot1

Which is dumped in boot loader
via backup options
backup emmc BOOT0/1


So please make sure you have all those files in those folders on your sd

then try the kezplez.nro again

Thx for the reply, guess I will just start over. Now that u mentioned it it might have not backed up tsec keys, I didnt think to check that either, for I had no idea kezplez would use those files. Will update when I'm home and tried again!

When I follow this guide, the counter goes to 17/19 then my switch gives me an error prompting me to turn the console off. I've tried it multiple times and same thing. When I check my keys.txt there's only like 26 keys.

When I do it on cmd, Its working and then gives me error for can't find sd_...._..... and only gives me like 17 keys. BTW, I'm on fw 1.0.0 and I've tried both fat32 and exfat format with same results.
