Guide

Getting your nand keys

Boot your switch in RCM mode and launch the BisKeyDump payload, it will show several keys and a qr code.
We need the two "BIS Key 2" keys one called "tweak" and the other "crypt", copy them to your pc and double check. Alternatively you can scan the QR which is a text file with all the keys but not all phones scan it correctly.

Mounting the nand

There two ways to do this : From a nand backup or directly through usb. The usb way is faster but since we are going to directly mount the switch nand make sure to not modify any file or you might brick. Using a nand backup is safer because you can just delete it if you mess something up. Follow ONLY ONE of these options :

From USB

Fully read this part before attempting it, also make sure to have a nand backup.
Download the memloader payload by rajkosto and run it, choose ums_emmci.ini, connect the switch to your pc, windows will not recognize the filesystem and might ask to format CLICK NO or else you'll brick.
Now open HacDiskMount click on File and Open physical drive, select your switch from the list (should be called Linux UMS drive, the size should be ~29GB).
If you did everything correctly now you should see a list of all the partitions on your switch nand, skip to the "Dumping the home menu" section

From Nand backup

The files we're dumping are firmware-depended if your backup is on a different version than your switch themes won't work on your switch (but will if you restore your backup) Open HacDiskMount click on File and Open file and open your nand backup, now you should see a list of all the partitions on your switch nand.

Dumping the home menu

Double click on the SYSTEM partition, a window should appear, write the two "BIS Key 2" you got earlier and press on Test, if it doesn't say OK then you got the wrong keys.
If you don't have it already click on Install to install the virtual device driver, HacDiskMount must be running as administrator.
Select an unused drive letter, check the read-only box and click on mount. Now open the drive you just mounted and go in the "Contents/registered/" folder, you should see many folder with alphanumeric names, find the right one for your firmware : Home menu :

  • for 4.1.0 a4d340a9b2ba9077a9495eadd9d87561

Once you find the right folder copy it to your pc, inside it you should find a file called "00", it's an nca, use hactool to extract it:

hactool 00 --romfsdir=romfs

Now you should have a folder called romfs with all the files you need to make custom themes.

Before closing hactool remember to unmount.
