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 this morning I tried to reset my v1 switch running atmosphere 16.1 to payload and it black screened.

It does not have autorcm running and it had 97% battery at the time.

Now it won't boot to rcm or ofw no signs of life at all. No battery charging symbol or anything.

I have held power for 60 seconds and combinations of power and volume + vol - and both with power and nothing.

If I unhook the battery and then plug back in will this bring it back to life or does anyone else have any ideas. I have tried rcm with and without sd card and jig but im currently getting nothing at all on the screen.

Small update. Briefly I got ut into rcm mode but like an idiot i forgot to put the sd back on so it failed after sending the payload and now I can't get it back but I will keep trying.

As a side note I did recently use daybreak to downgrade from 17 to 16.1 so I'm suspecting this is possibly dye to a burnt fuse as I updated it to 17 the official way
