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.

Hi, I just make a friend of mine hack my switch with a picofly. It worked ok, i even boot into Sysnand and I make the backup and everything.

The problem comes when I reach my home and put the switch with no sd card in the dock, after that the console just dont turn on anymore.

I look for ligths from the chip and nothing show up, pressing the power button for 20 seconds also don't work apparently. My friend asked me if i can heard a sound from the vents that are behind the switch, and yes there was a sound, so I manage to turn off the console by pressing the button and not hearing the sound anymore.

So, what may be the problem here? It can be reapaired?

Probably nothing is broken.
You need that SD card with certain files on it.
The whole point of your picofly is to boot a custom firmware like Hekate that is on your SD card.
Just ask your friend to prepare such an SD card.
