Some information that needs to be addressed:

• SX OS and Atmosphere now supports proper LayeredFS, instructions for using it has changed since this tutorial was made
• Supported Firmware information is out of date
• LFSKit needs to be updated to properly support non 5.x.x firmware

How to use LayeredFS for Backup Loading

Firmware Supported: ONLY 5.x.x
Use the PRAGMA LFS Kit below.

PRAGMA's LFS Kit

DOWNLOAD
SOURCE

• Go from NOTHING in your SD Card to playing a game backup in a few clicks!
• Decrypt .XCI -> romfs/exefs folder with main.nmpd auto edited aswell as folder's name auto renamed to donor titleid
• Download NOTHING except LFSKit!

ENJOY!

Picking a Donor Title and getting Donor TitleIDRunning Game Backups!

1. 
   
   1. A donor title is the application we will run to open the backup.
      Pick a game you don't care about (Download a Demo or a free game from eShop, for example Octopath Demo)
      saves are something no one knows much about, we don't fully know where or how they are stored.
      They might overwrite the donor titles save, so seriously pick a game you DONT care about, not a game you rarely play.
      
      
   2. I also recommend picking a donor title/game combo that has been tested and reported working just so you know if YOU did something wrong or not.
   3. Find the TitleID of the donor title you chose from http://nswdb.com or http://switchbrew.org/index.php?title=Title_list/Games
      Region must be the same, choose the TitleID for the base-game NOT for the update title, even if your updated.
2. 
   
   1. Once again, boot into Hekate-IPL (Step 1).
   2. Enter "Launch firmware" and select "RomFS".
   3. Your now in your system's home menu.
   4. Open the Donor Title you set the TitleID of on that folder and .npmd file earlier.
   5. The game will load up flawlessly.
      If you opened the Title lets say, Fortnite, and Fortnite booted, the titleid of the folder in sd:/atmosphere/titles/{fortnitetitleid} doesnt exist, or doesnt start with 0100.
      If it gives you an error screen, either you didnt edit the main.npmd properly, or its an incompatible title/donor combo.
   To see which games work and which dont using which donor titles, look below.
   If you notice that you used a combination of Game and Donor title that isnt in the list below, post in the thread and I will add it. (look under to see what I need to add to chart).
   

Troubleshooting

• Black Screen/Infinitely Loading
  Leave it for around 5 minutes then press the home button and go back into the game without closing it. Often this can do the job.
• Freeze when Loading
  Close the game and try again, its a common occurence, you may have to try up to 4-5 times before getting it to work, sometimes you may even have to reboot between retries.

Check if you have master_key 01, 02 and 03 in your keys.ini. That was my problem. I'm assuming your method created that.

There are a bunch of keys in the text file but most of the titles rather end with _00 or _04.

I've been trying to get this to work on my 5.1 switch, with not much luck. When booting into romFS, it hangs on one bit and then the screen turns to this:

I double checked my files, too.

Unrelated, but HBL doesn't work on CFW, just goes to normal album.

I was having the same issue. I was using Pragma FS kit and when I was looking through the SD card I found that the FS.MITM.kip was 0 bytes. Found the file on a discord server put it on the SD card and it now gets past that screen but it is giving me "An error has occurred" Error-Code 2001-0123 as soon as I get past the Nintendo logo. BTW I am on 4.1.0

 

[gamemasteru03]

Hm...I'm not familiar with this tool but if you have the keys and hactool I recommend using the .bat file method instead. This basically creates the exef folder and xciDecrypted folder (containing the NCA file). Much more convenient and error free.

Well I still got a romfs and a exefs so I'm gonna try using the files but if they don't work ill try this tool next.

Just as a PSA I guess: PRAGMA's LayeredFS Kit seems to be borked. Use XCI2TitleConverter to extract everything, and use the main.npdm patcher website to patch the main.npdm.

Well I still got a romfs and a exefs so I'm gonna try using the files but if they don't work ill try this tool next.

Problem is: if it tells you something is corrupt not all the data will be extracted hence you might end up with a bad romfs file (the game won't boot on your Switch).

 

[gamemasteru03]

Search for

master_key_01
master_key_02
master_key_03

In your keys file.

I see two keys called master key 00 and master key 04 but I don't see any other master keys.

Well it just finished copying to my sd card so ill try it and see what happens.

I sure wish there was an offline tool to patch the main.npdm file!
Anyways related but worth checking: once you load the npdm file patcher website, it works offline too (it's in javascript that must be why)!

Not yet, bcs is tested Fifa 18 first.
But ive cant enter the game properly.
i cant accept the license agreement, maybe u or someone else can help?

Try Fifa with Octopath Traveller Prologue demon as the donor, that worked for me

--------------------- MERGED ---------------------------

Well search up for the keys and then add them in the same format

So

master_key_01 = 54E1...

I'd recommend you use notepad++ as it'll format the file correctly and make adding them easier, using notepad is really annoying.

This. I got errors using notepad because the spacing was incorrect. Wordpad is fine

Doesn't work on 4.1. Check the OP.

Do I need the other keys or just the master keys? Also do they need to be in a specific order or not?

Quick question: I put the appropriate files on the SD card, then got biskeydumpv6 to run on the switch and now my phone is unable to do anything with the QR code given. I've tried multiple programs and I've even made certain that the programs notice qr codes normally by googling QR Codes and trying 3-4 of them to make sure they work. Is there any way to actually use this QR code or am I just going to give up because there's no way I'm copying by hand 4 32-length hex numbers and getting those right. I'm only human.

Did it have a blue background? If so the QR code should display a bunch of information on your phone including your BSK and TSEC keys (if I remember the key names correctly). So you can email them to yourself from the phone etc to get them onto the computer.

 

[runetoonxx2]

For the ppl who got Bayonetta working...
Did u use the BBB jap dump of it or did ya use a US dump from somewhere????
I can’t seem to get it working and I’m using the BBB dump

 

[gamemasteru03]

Should just need the master keys, don't remove all the other keys if that's what you're thinking and the order doesn't matter.

Thanks.

It did have a blue background. I never turned it off either. Funny thing is, my phone's QR program doesn't "just work" like the people here seem to think it does, but my phone can absolutely use normal QR codes. I'd love to get that dialogue you're talking about, but there's no reaction at all. Any actual help here?

 

[renes2]

Try differnet QR Code REader, that really helps.
I tried 4-5 so far, and only 1 worked lol(German, "Blitz QR Scanner, Developer Application4u)

Hi
I had this issue also the first time around. You might want to grab a different QR code reader from the playstore. After a few tries, one accidental try actually worked!
