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.

IGNORE THIS!!!!
Posted a new correct post.

======================================================================================================

I've been planning to re-paste thermal paste for my V2 switch (2019).

It doesn't get seriously hot, but there is definitely an increase in heat fan noise and heat overall. Plus I think it needs little bit of cleaning and servicing! I have serveral years of experience with PC parts and larger consoles, but this is the first time I'm taking apart something small and delicate as the switch.

Im planning to do the following to improve the thermal performance of this device, please let me know if I've planned something wrong or anyway I can improve these.

Remove the metal CPU shield cover shim (or whatever thats called) and re-apply thermal paste there (Noctua NT-H1, surface will be cleaned with Arctic Clean Kit + 70% alcohol wipes).
Put thermal pad on memory modules (options below)
2.a - Put a 0.5mm thermal pad in between the shim and the memory module
2.b - Put only on top of the shim not inside it (but I feel like there is not enough contact between the modules and the shim
2.c - do both above.
Then reapply the paste between shim and heat-pipe
Then between the pipe and the shield plate
I also wanted to know If I can replace the foam pieces on heat-sink with standard duct-tape -----or----- some thermal pads? (Thermal pads on heat-pipe will be a bad idea when it comes to heat dissipation) - I have a feeling they are tightly glued and may tear when removing the heat-sink, just being ready.
