Hello guys, this is my first post here! I just got a MIG Switch card out of curiosity and I was tinkering with it. For those who don't know, it's used by placing XCI dumps as well as other game specific bin files in the sd card of the MIG Switch, and are obtained from the original cartridge by using an app like nxdumptool. Two of these bin files are mandatory to get the game to boot: Initial Data.bin and Certificate.bin. They stay the same for every cartridge of a specific game. Now, if you want to use an XCI dump from a shady website it's impossible to get it to work without those files. By using the Certificate.bin from another game it has no problem, but this does not count for the Initial Data.bin. So I looked for a way to obtain this Initial Data from an XCI file and read a bit of the XCI file documentation from switchbrew dot org. Here's what I understood so far: The Switch checks if the cartridge is valid by doing a challenge–response authentication on the Initial Data. The Package ID is contained both on the XCI and the Initial Data, on positions 0x110 and 0x0 respectively. The Initial Data hash is on the XCI at position 0x160. It is calculated by doing a SHA-256 hash on the full Initial Data content. So I was wondering, is there a way to to construct a functional Initial Data file starting from an XCI dump? I also tried a reverse approach by editing the Package ID in the Initial Data from another game, generating the Initial Data hash and putting it in the XCI file but is not enough to get the Switch believe it's a real game. Sorry if this may seem stupid but let me know what you think.

RESTORE SWITCH WITH OLD BACKUP

Hello everyone,

I have already read a lot here, however it seems none of the existing threads does really cover my case. I wanted to summarize the process i laid out in my mind and see if my thought process is feasible.
I have a first generation switch that I bought with 6.2. before I started with CFW, I made a full backup.

I'm now on version 16.0.1 and have also burned 18 fuses. I'm not sure if I've done anything in between that might have left corpses on the original nand. So I want to have a clean restore of the switch and had the following idea.

I do restore to 6.2.0 with hekata or NXDump Tool, then boot directly into ChoiDujourNX and update to 16.0.1. So I should be back where I am now, and i am sure that i have a 100% clean Nand. AutoRCM is ON

Do you think that would work?

Thank you very much for your feedback and help.
Greetings
