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.

Replaced the M92 chip (I've heard it called the Charging IC) and the P13USB chip as well. No missing capacitors or any tech related issues, but I'm stumped as to what can be causing it. I've tried the basics (I tested the basics before as well, which is how I got to the point of a board level issue) and both the battery and LCD are working just fine when I test with my working one. I did some forum digging here and found a diode mode reading for the P13USB chip pins, and most of them are a little under (like it should read .432, and I get .37) but one pin in particular reads 0.0. I'll post a photo to help give a better idea. Anybody have any tips for how I can troubleshoot that open line?

The pin you have 0 reading is VDD line .meaning you may have a short occurred on this power line. Remove pi3USB ic and see if this pin diode value comes back, if not remove M92t and check again.
This should be the reason why your switch wont boot
