Backup/Restore your Nand + Get your biskeys+tseckeys+keys.txt
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
- 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.
- 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
Join or Merge RawNand Parts guide into 1 file
Download this first >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
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”
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”
- 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”
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”
17.When complete, return to Tools menu
18.“Select “Backup”
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”
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.

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
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)
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
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
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!!
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.
