Scans a Nintendo Switch NAND dump and identifies its firmware version and whether exFAT is present based on the names of the .nca files in SYSTEM:/Contents/registered. '''Author's note:''' Python and command line can be difficult for unfamiliar users, so if possible, it is recommended to use the [[NxNandManager Switch|NxNandManager]] tool, which among other things can list the firmware version of a NAND backup. ==User guide== Requires Python 3 with pycryptodome (pycrypto works too): pip install pycryptodome If this is an encrypted backup like Hekate makes (ie. you haven't dumped a decrypted System partition via [[HacDiskMount Switch|HacDiskMount]]), you need to provide your console-specific BIS key 2. Dump this using [[biskeydump Switch|biskeydump]], and save the output to a text file to pass to <code>FVI</code> via the <code>-b</code> option. Then run from command line: <pre> 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 </pre> ==Screenshots== https://dlhb.gamebrew.org/switchhomebrews/firmwareversioninspectornx2.png https://dlhb.gamebrew.org/switchhomebrews/firmwareversioninspectornx3.png https://dlhb.gamebrew.org/switchhomebrews/firmwareversioninspectornx4.png https://dlhb.gamebrew.org/switchhomebrews/firmwareversioninspectornx5.png ==Compatibility== Tested under Windows 10 with Anaconda Python 3.6.5 and Ubuntu 16.04 LTS with Python 3.5.2. ==Credits== <code>crypto.py</code> module is from [https://github.com/ihaveamac/switchfs/blob/master/switchfs/crypto.py switchfs] under MIT license - it was in turn ported to Python 3 from crypto.py gist by plutooo Big thanks to the [https://en.wikipedia.org/wiki/Design_of_the_FAT_file_system Wikipedia entry on FAT layout] - being able to read the dump disjointly means FVI only needs to fetch and decrypt a small handful of clusters rather than the entire 2 or 32GB file. == External links == * GitHub - https://github.com/shchmue/FVI * GBAtemp - https://gbatemp.net/threads/firmware-version-inspector-get-fw-version-from-nand-dump.515308/
