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.

Okay so i've posted before a while but i've gotten my issues solved but i'm having completely new issues now where my hwfly chip isn't booting. The light flashes purple as it does for about 20 seconds before flashing orange, then it either turns solid yellow, solid red, or just turns off. I was able to fix it in the past by resetting it with PuTTY, but unfortunately the usb debugger tail my chip came with broke. I heard you can reset the chip with a modding jig the same way you boot into rcm, but i haven't had any luck. I checked all the solider points, they all seem to be fine, i don't have a multimeter to check them personally but nothing is loose at all. Someone else modded my switch for me and i don't really have the means to fix it myself if i need to soldier. Does anyone have any advice or sollutions?

Take it back to your installer, have them probe all points. Your woes aren't your problem to fix, that's why you used an installer, use pic for reference.
