Restoring a NAND Backup
Restore a NAND backup to the Switch¶
Warning:
-
This will reset all of your saves, games, system version and other system settings back to the point of when you made the NAND backup. Keep this in mind, as you probably don't have to restore a NAND backup unless you have bricked your Switch or want to go back online safely after using CFW.
-
If you're going to restore an old NAND which will downgrade your firmware it's best to create a second NAND backup before restoring the first one in case something goes wrong.
What you need:¶
- Your
rawnand.bin
(Combined or in 15 or 30 parts) - Your
BOOT0
andBOOT1
- If you're missing any of the files above, ask for further help in the Nintendo Homebrew Discord server.
- The Hekate Payload
- A microSD card larger than 32GB
Instructions:¶
Before we start, check if you have a tree of folders called backup/[8 Character NAND id]/restore
on your microSD card.
If you don't see a backup or [8 Character NAND id] folder on your microSD card:
This means you do not have a nand backup, it is highly recommended you make one as soon as possible. Follow the steps below to make one.
- Launch the latest Hekate payload on your Switch.
- Navigate to
Tools
>Backup eMMC
>eMMC BOOT0 & BOOT1
and let it do its thing. - Wait for the process to complete. When it's completed, you now have a
backup/[8 Character NAND id]/restore
folder on your microSD card. Continue with step 1 of the instructions below.
- Enter RCM and inject the Hekate payload.
- If you use a modchipped Switch, you can simply just turn your Switch on with the Hekate payload renamed to
payload.bin
on the root of your SD.
- If you use a modchipped Switch, you can simply just turn your Switch on with the Hekate payload renamed to
- Navigate to
Tools
>USB Tools
>SD Card
and plug your Switch into your PC via USB. - Copy your
rawnand.bin
(combined or in 15 or 30 parts),BOOT0
, andBOOT1
to thebackup/[8 Character NAND id]/restore
folder on the microSD card. - Eject the
UMS
device safely from within your computer's operating system. - Navigate to
Tools
>Restore eMMC
. SelectRestore eMMC BOOT0 & BOOT1
. Wait for this process to complete. - In that same menu, select
eMMC RAW GPP
and wait for the process to complete.- This will generally take a long time to complete, the time it takes depends on your microSD card's specifications. (10-15 minutes is expected.)
If you're downgrading using your NAND backup
If the security version you were on before you performed the NAND restore is HIGHER than the NAND backup itself, you have to enable autoRCM to not get stuck in a boot crash.
- Note: This section can be disregarded for modchipped Switch users.
A system update is considered a security version when a fuse is burned, you can check which versions burn fuses here.
If you were in AutoRCM before you upgraded to a newer security version (and still were after the upgrade) you don't have to do this.
- In Hekate's main menu, navigate to
Tools
and go to the bottom of the page where you will find a button calledArchive bit - AutoRCM
- Select the
AutoRCM
buttom and you will seeON
written next to it. This means it is enabled.
