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.

Hello folks,

I recently bought a switch oled pcb with missing components near pi3usb ic. Does somebody know the values of the missing components?

Thanks

Okay, thank you. i will order them right away. I noticed the 3,3v rail is shorted too, but im unable to find the shorted component. Everything else looks fine too me. What can cause the 3,3v line short? removed some caps on the 3,3v rail, but so far the short is still there.

the pi3usb itself can cause the short.

okay, i removed the pi3usb ic and the short is still there. Gonna try to remove the M92T36 and check if the short is gone.

EDIT: Short is still there. M92T36 removed and pi3usb removed. Any other suggestions?
EDIT2: Found the short. It was the cap of the M92T36....
