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 guys,

This weekend i decided update my switch, i was on FW 8.1. I turned off my switch to take off the sdcard an copy the new fw files to the card for the update. After reinserted the sd card, i tried turn on the the switch and... nothing, the Switch does not turn on.
After some mini-hearth attack, and few tries pressing the power button, the switch turn on and boot on OFW (i dont have AUTO RCM). Turn off again, and switch not turn on.. again. Few tries pressing the button again and switch turned on. This time i could make the payload and boot um emunand without problems. update de FW, reboot (without turnoff), all goes well.

Testing the power button on horizon, the button appears to be ok, not fail on press, open the POWER menu every single time, so i dont believe that could be some hardware fail ON BUTTON, but how knows...

Any thoughts about this? i really concerned for future updates.

thx in advanced and sorry for the poor english.
