[Switch] TUTO – Dump the NAND from the console with hecate is

Well, now that you’ve bought a Nintendo Switch and have taken advantage of the infinite joys of the hack thanks to the method of the RCM, you must now tell you that a potential brick your console might be able to provide because of your multiple hacks on the console, and you’re right ! In this tutorial, I will teach you how to protect yourself in case of brick of your console, showing you how to copy the system of the Switch for power then to restore it in case something goes wrong !


Well, then before we begin, I must warn you that these manipulations are to be done with caution, it is for this that : neither I, nor Custom Protocol, or the application author can not be held responsible in case of wrong manipulations with your console, do this at your own risk !

Me finally, if you follow correctly this tutorial, you’ll have no problem for sure ! 😀 If you want, I’ll go through the first step which is… the pre-required !

0) Pre-requisites

To begin this tutorial, you will need :

  • A Nintendo Switch in FW 5.1.0 AND THIS FIRMWARE ONLY ;
  • A microSD card of 32 Gb formatted in exFAT ;
  • The files available just below this topic ;
  • Know how to inject a payload, as well as start-mode CM (click if you don’t know how to do it).

1) Implementation

Well ! So start by unzipping your archive, which should normally contain two files ; the first is called ” SD Card Switch “, it contains all the files needed to dump the NAND, we’ll get to that after. The second folder is called ” TegraRcmGUI_v2.0 ” ; this is the one we’ll use for now.

To begin with, therefore, extract the two folders (at least it will be done), and then open the folder ” TegraRcmGUI_v2.0 “, you should find yourself in front of a multitude of files :

Wow, this is beautiful :’)

So I invite you to run the software named “TegraRcmGUI.exe” a new window should then appear :

For people who have followed the tutorial to Wirus for injection of payloads, you should normally have the necessary drivers installed on your computer. For others, I invite you to place this section just below !

Begin by going into the “settings” tab in the top left, then select the “Install Driver” button, the installation should proceed normally, and… here You are with the drivers !

Now, select the payload ” hecate is-ctacaer-2.3.bin simply by clicking on the magnifying glass next to the grey button ” Inject payload “.

Let’s move on to step 3 ! 😀


3) installation on the SD card

Before you begin, verify that your SD card is in exFAT and not FAT32 ! Why exFAT ? Simply because the NAND of your console is well over 4 Gb, and if your SD is FAT32, the card will not support files over 4 Gb…

Well, insert your SD card into your computer by the method of your choice, then you should normally see a folder “Nintendo” at the root of it, don’t touch (if you don’t have this folder, insert your SD card into the console turned on, so that the console creates the folders). Simply extract the contents of the folder “SD Card Switch” to find you, with all this multitude of files :

Sorry if the image is too small, click it to see clearly >.<

From this point on, don’t touch it, everything has already been done and only requires to be put into your console quietly ! Now, let’s dump !


4) Dump

BEFORE YOU BEGIN, MAKE SURE THAT YOU LOAD YOUR SYSTEM TO 100 % ; IN FACT THE DUMP IS GOING TO LAST 40 MINUTES AT THE MOST !

Switch off your console, then insert your SD card. Start-here-mode RCM using the method of your choice (the link to the tutorial is available in the prerequisites above), then connect your console to your computer and inject the payload , by clicking on the button ” Inject payload “, which normally should become clickable.

On your console, you should see a new menu : it is hecate is, a Custom Switch Bootloader (not to be confused with a Custom Firmware), I invite you to use the volume buttons “up/down” keys to navigate and POWER button to select a menu :

A menu pretty simplistic

Navigate to the tab “Tools” with the keys volume ” up/down “, then once on it, and select it by pressing the POWER button, you should normally find yourself on a new tab like this :

So here you have two options, or you start with the longest, namely, the NAND (about 40~50 minutes) ; or you choose to do the boot (about 1 second).

In order to do it in order, I recommend you take care of the NAND first, then finishing with the boot. To do this, it is stupid, so if I swear !

  • To dump the NAND, select with the help of volume buttons “up/down “option” – Dump RAW eMMC ” ;
  • To dump the BOOT, select with the help of volume buttons “up/down “option” Dump eMMC BOOT “.
A) Dump of the NAND

When you have selected the dump of the NAND, a screen like this should appear :

Finally !

The process will unfold in two stages :

  • First, it will perform a complete copy of the NAND (the longest) ;
  • Secondly, it will check the integrity of the NAND to verify that you did not provide a corrupted file (it would be a shame huh ?).

During this period of time, go and see your favourite series or you can take care of your wife/dog/child is a good idea, leave your console in a corner where nobody can touch it, and wait calmly, enjoy the life, you know ! 😀

B) Dump of the BOOT

Well ! Now the NAND should be wisely copied on your SD card ! For now copy the BOOT, I invite you to follow the previous steps, but this time selecting the other option which was… “Dump eMMC BOOT” !

Very fast isn’t it ?

Press any key, then go back to the menu of the departure, then simply select the option to “Power Off” all the way down like the picture below to turn off the console and remove calmly to your SD card :

We finished !

Nos fameux dumps

Our famous dumps

And voilààà ! After you have properly removed your SD card from your console and have it connected to your computer, you should end up with this inside !

The files BOOT0 and BOOT1 are the files in the boot of the console and the file you see below is in fact the NAND itself ; these files are keep in a safe place on your computer, don’t hesitate to make copies on external hard drives or even on your cloud !


It is with great joy that I announce to you the end of this tutorial, if it helped you sleep well this night, please let me know in the comments and don’t hesitate to tell me if you have any questions about this article, I will answer with joy to help you !
