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.

modded with: Atmosphere/Kosmos, cFW reiNx, homebrew, usb-hdd (for games) and so on.. the basic stuff.
but,your right. its harder to mod a patched switch,then a non-patched one,but it is possible (my switch has XaJ4006+ and modded!).

Sounds like your either confused or spreading bullshit. Ipatched units can NOT currently be hacked. End of. Stop talking shit!

true,you cant currently mod your patched one,because you dont know where to get the tutos for it and the tools..but please, just pls, shut up if you cant get it by yourself. btw, if you can read "the serial of my switch",..and then tell me again,its not "currently" possible..you fool xDDDD

You are lying, take a video of it loading up Hekate, and Atmosphere and show the serial number and system firmware in default theme.
