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.

Seem to be having some fun and games with my switch.

I have a day 1 switch, that's exploitable. Everything was fine, console had full battery.

Turned it off via the Power off option on the console. Turned it back on, nothing. I've not got AUTO RCM turned on or any exploits running at this stage and was on standard fw.

Turn it on, nothing, doesn't boot. I plug it into my dock it flashes red once but nothing on the switch screen.

Pressing and holding the power button for 15 seconds and turn it on, nothing.

Pressing and holding the power button and both volume buttons and then releasing the power button it wont go into recovery mode either.

However if i press and hold power for 15 then try to go into RCM Mode using power and volume up with a jig, my PC will see it in RCM mode but i cant seem to load a payload to it. Really odd. Literally all i did was turn it off. Ive been told to let the battery deplete and try again but anyone ever seen this before?

Hardware Switch won't turn on?
