Thanks for replying!
1. So, after pushing the payload, if I disconnect the USB and connect it to the charger, I will be fine, right?
2. Also, do I need to constantly make sure that the screen is not "turned off" when the dumping is in process?

Just let it do its thing, it will verify anyway. and yes you can have it unplugged but ovb make sure battery is charged first no screensaver or standby your good

I didn’t ever connect my console online after running cfw for the first time. also, I was careful enough to backup my clean rawnand before running cfw, just so I could restore it prior to going online.

I ask about clearing logs because I’ve read somewhere it could raise bad flags and get you banned.

however, now that I think about it, doesn’t restoring a nand also clear the logs? or maybe it only clears the logs attained since the time of the backup?

If you have never been online with it, then sure clear your logs if you wish...that report you mentioned was due to two different logs from the same system in such a short time.. if you never been online it will not matter... the logs are stored in nand.

Since I never used kezplez before the brick, I had to do some googling for my keys.txt, but I found it at three different sites, so they're extremely likely legitimate.

You have not given your keys path...Also i dont think desktop best place ...Your missing hactool

Make a folder called Choi on your desktop
Copy keys.txt to Choi folder root
Copy Hactool.exe and files to Choi folder root
Copy Choidujour.exe and files to Choi folder root.

Then use TWO commands...

Code:

cd C:\Users\YOURUSERNAME\Desktop\Choi

Code:

ChoiDujour.exe --keyset=keys.txt c:/users/YOURUSERNAME/desktop/firmware6.0

conradcervantes · Sep 25, 2018

I'll give this a shot. Sorry, my keys.txt was set in c:/users/myname/.switch/prod.keys/

Edit: Success! There were a lot of extra items in the keys.txt that needed to be deleted to ChoiDujour to finally run, but I should have everything I need to move forward. Thanks, @Canna!

Canna, firstly, thank you for taking the time to write this guide. I'd like to ask you a brief question:

I have a 4.1.0 switch i bought new from a retailer recently and have not connected it to the internet or done anything CFW on it, but i have been playing cart games on it

according to another thread, as an XAW1006xxxx serial it's safe for bootrom exploit

my question is, should I initialize the system again before taking the initial NAND backup to get the cleanest image or is that unnecessary?

I'd like to ChoiDujour up to 5.0.1 to play octopath on a cart without burning fuses while waiting for everything to develop further

I'm interested in keeping the switch offline until pokemon / animal crossing and I'm aware that an initial nand dump is vital to keeping the switch clean until the first time I go online so I'd like to do this the best way possible. i'm not interested in playing backups or anything like that.

If its a virgin nand.. (untouched) by cfw or homebrew then... Then thats the cleanest.
You say you have not done any hacks or cfw or homebrew so then its what i like to call a virgin nand...

As for reinitialise it does not matter in your case, remember ...
what ever you backup is what exaclty it will restore.

so if you backup 4.1.0 virgin nand. settings files account username saves
you will restore 4.1.0 virgin nand. settings files account username saves

Yes make a full backup with the guide,
Towards the end of guide i will ask you to run CFW if you wanna get your keys for decryption/encryption of nca files /game files/updates.... keys.txt is needed for choidujour method when using the no burn fuse guide...
Keys.txt can also be found online anyway....

If you wish to follow the guide 100%, after you done everything you can use the rawnand.bin you just backed up and restore it to remove traces of cfw or go back to virgin nand....

Do I have to re-backup everything when I update? I just updated to 6.0.0 and I'm not sure whether to keep my backup files from 5.1.0 or replace them. Or if I have to re-backup, do I have to backup everything again or just certain files?

if you dont make a nand backup for the system version you are on
the only way to do it then is to rebuild your old nand into a newer version..

Either make a backup of your 6.0 nand now
or make yourself a rebuilt nand with your old backup

your old backup is still good to have incase something goes wrong and you can rebuild with the old...

But i suggeswt you make a new backup n and hell keep both....

You dont need to do the biskeys parts or keys.txt if you already have them just need boot0/1 and rawnand,bin

Will the guide be updated for those who have SDXC formatted microSD cards that the Switch supports?

I have a launch date Switch (April 2017) with 3.0.0 firmware before v3.0.1 was released, and has already updated with SDXC support.

SDXC that is just a type of sd card, it has nothing to do with the format...
read this https://www.sdcard.org/consumers/choices/file_system/index.html
theres only two fats supported i think by the switch

Extended fat.. exfat
and fat 32

both exfat and fat32 work with the guide

so if you format your sdxc card to exfat or fat 32 it will work..

Ok, so what kind of format do I already have that Nintendo Switch formatted to?

Canna · Sep 26, 2018

the switch is not formatted.. its the sd card that is formatted..

The switch will use Exfat for sd cards or fat 32

Fat32 format has limitations of file size upto 4gb were as exfat can hold 32Gb plus in file size , if you already have the sdxc update then use exfat format for your sd card.

delete12345 · Sep 26, 2018

Okay, so my microSD is formatted by Nintendo Switch to be exFAT, after the SDXC update to allow the Switch to read SDXC microSD cards. Thanks.

This Multi Guide Will help you back up your nand, Backup your system information,

Restore your nand, and also Make exfat work on lower system versions.

Only use the files attached if your following my guide/thread
I also recommend you Backup your nand before any
modification of your system to make yourself a clean backup / A Virgin Nand
Also not to use auto rcm Until after your backup

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

Preparation:

You will need a micro sd card formatted to exfat or fat 32 with atleast 32 gb Of free space to follow this guide and guides.

You will need to download the files i have provided
Download all Files attached at end of this guide,And extract these first to your pc

For Fat32 users only >>FAT32 Mini Guide

Download this first click here > >joiner_scripts_for_windows_linux_macos.zip

to combine the 15 parts or 30 parts of rawnand 00.bin etc into 1 rawnand.bin file
Place the correct script into the folder were 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 were 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

Ok lets try keep this simple Backing up

Firstly
you will want to set up and install your payload sender TegrasmashGui to
and install your apx driver this application is found in the zip i provided..

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 hekate.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 select Launch option on hekate main menu,
Then select Biskeys From the tools section by pressing the power button

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

This section below about booting into CFW may not work for all of you on some system version, or if your not using exfat. Do not panic or worry about this, as the keys.txt file can be taken from your switch in any of the CFW methods like reinx ,rejnx ,SXOS, atomosphere. Basically any method you can launch into Homebrew menu to load Home brew app Kezplez. you could also read the exfat guide On my main post if your having trouble running cfw or accessing homebrew menu to update your lower system version to have exfat support

So now you will need to restart your switch and load back into the hekate bootloader menu to do this load the hekate.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 option

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

If you have a error When trying to use kezplez, Please Try Guide Below,If you don't you can skip Kezplez error guide

Kezplez error guide
A Big Thanks @shchmue For sorting out the bugs and for her work on the kezplez issues.

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

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 inside the letter and number folder 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
in there should be

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

If you do not have boot0 and boot 1 on your sd card root then please copy them from the backup random number letters folder as well

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

then try the kezplez.nro again

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 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 program 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

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

And thats 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
Do this at your own risk And please to make sure to read the blue text in my Backup guide above when you made your backup
Also Make sure your battery is charged Or atleast enough to complete the restore process to be safe fully charge the battery Or keep the switch plugged into a power source usb cable should be fine
Also please make sure your sd card is in exfat format (Important)

Restoring your nand.....

Providing you have followed my guide above to backup your nand
You should have 3 Files in your backup folder
(Plus some other files we wont be using for your restore)

boot 0 boot 1 rawnand.bin

If you do not have these files please do not continue

Step 1
Copy from your number and letters folder inside the backup folder on pc these files > Boot 0 and Boot 1 and Rawnand.bin
and place them in the restore folder on your sd card

Example on sd card
inside The folder Backup>numberletter folder>restore folder <....place files here...

Step 3
Put your Switch into Rcm Mode
Boot into the hekate bootloader *Hekate.bin*
By using tegrarcmsmashGUI

Step 4
Now once your on the bootloader hekate main screen

Select tools option with the volume +/- buttons and press power button to select

It the tools section,Select Restore

Step 5
Now in the restore options screen
you will want to select
Restore emmc BOOT 0/1
You will be warned and asked are you 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 anytime)

Step 6
Still in the restore options screen

Select RESTORE eMMC RAW GPP and press power to continue
You will be warned and asked are you sure. to continue press the power button and wait for the process to finish now this will take some time Once finished press any key to go back (do not power off at anytime)

Step 7
Now considering all processes went smoothly and you got no errors
you should now be restored
Go back to the Hekate main menu by selecting back

On the main menu select power off.
Then reboot your switch as normal with 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

At this time i have not made the exfat guide myself so untill i do i thought id link to another exfat guide ,
Please like his thread if it helps you and mine if you like the information i provide

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).

If i have helped you, Or you like my post
Then Please hit that like button it will help me a'lot thank you
