Hacking RELEASE Firmware Version Inspector - get FW version from NAND dump

Good news! Now you can quickly find out what firmware version a given backup contains.

Download:
Firmware Version Inspector - by shchmue on Github

Usage:
Install Python 3 and pycryptodome. In command prompt, type:

Code:

pip install pycryptodome

If this is an encrypted backup like Hekate makes (ie. you haven't dumped a decrypted System partition via HacDiskMount), you need to provide your console-specific BIS key 2. Dump this using biskeydump (https://gbatemp.net/threads/biskeyd...c-decryption-real-time-mounting-tools.502434/)

Then run from command line:

Code:

python FVI.py [-b=/path/to/biskeyfile] <dumpfile> biskeyfile must contain the following lines: BIS Key 2 (crypt): <32-digit hex key> BIS Key 2 (tweak): <32-digit hex key> omit -b if System partition already decrypted (eg. dumped with HacDiskMount) dumpfile must be NAND dump (eg. Hekate rawnand.bin dump) or System partition

I tested this on Windows 10 with Anaconda Python 3.6.5 and Ubuntu 16.04 LTS with Python 3.5.2. I hope you find it useful

This is useful, but I do have one feature request: an option to auto-rename files in a folder with serial number and firmware.

Support for 9.1.0?

Thanks for this, this tool is awesome! I was trying to figure out how to add 9.1.0 myself, may I ask how you found which .NCA it was to add into the firmware_titles.db?

shchmue · Dec 10, 2019

there are many ways. when a new firmware version comes out i get hactoolnet to output a list of which file name is which title ID and i end up referencing it a lot

this is the script I use to find firmware version from cart update partition, you may be able to tweak it for your own use

That worked!! thank you very much!!!

9.2.0 up

istovi · Mar 30, 2020

I installed everything but it won't let me check the files because it cannot find FVI.py. "No such file or directory found". I looked through all the responses in this thread and can't seem to find an answer. What do I do now? I'm on Windows, thanks in advance.

at this point since python is tricky to use for first-time users i'd recommend trying out https://gbatemp.net/threads/nx-nand-manager.533056/ nxnandmanager if possible

Python and command line can be difficult for unfamiliar users, so if possible, I would recommend the wonderful NxNandManager tool, which among other things can list the firmware version of a NAND backup.

Having an issue.

im using python 3.6.5, Windows x86 Executable from Python site. I'm not using Admin Cmd Prompt. FVI file is in a FVI folder on my desktop, and the paths for the other files are also on my desktop. I am not very savvy with cmd and terminal. Hope this is enough info to help.

I dumped with biskeydump (v9) on 10.1 and tried

Code:

python FVI.py -b=biskeydump.txt rawnand.bin

Code:

Does it require a 10.1 update to identify?

I was unsure if I updated to 10.1 before making a backup (though me and friend is pretty sure we did)..

I would like to verify so I am sure I can recover my nand backup safely.. Is there any risk to bricking if I attempt to restore and I remembered wrongly about updating first? Or can I simply backup again and restore that in case?

shchmue · Aug 7, 2020

yeah i need to update FVI for the new versions. and there’s no brick risk, if you’re on an unpatched console and you restore a backup even if there’s a fuse mismatch you can still boot CFW

Here is an updated firmware_titles.db that supports up to 10.2.0

shchmue · Oct 26, 2020

it’s updated to 10.2.0

You can also use the nx nand manager to determine the firmware version of your dump file. Just load the biskeys and the dump and that's it.

yes, i put that at the top of the first post a while back to encourage people to use that method

DrDoctor · Jun 1, 2025

Hi, does this still work? Because I'm getting an "Unrecognized file size" error, which I'm assuming it's because my backups are split in 2GB files.

Update: Merged the files into a single one with

Code:

copy /b rawnand.bin.* rawnand.bin

(I know that the last supported FW is 16.0.2, but it happens to be the one I'm currently on and all my backups are older)
