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.

So now I’m genuinely confused as to why my Switch is BSOD’d

I thought it was a RAM chip so when I tried to apply pressure to it and powering it up, it stays Blue Screened. But when I just bend the Console backwards it powers on like normal...

What is doing this? A bad digitizer? Is it really the RAM Chip? Is the motherboard Just busted? I’m genuinely confused...

Likely to be a bent Motherboard and/or bad solder joints on the NVIDIA SoC. I think @FXDX is the man for BSODs

The motherboard is litle bend and the Ram or NVIDIA SoC no longer makes contact with the motherboard. It's best to do a reball at Ram and if it still does then you do the same thing at the NVIDIA SoC. The motherboard should be heated and straightened with great care. You can also try a reflow.
