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.

Hi, this question may have already been asked but so far I haven't found a single solution to fix this and it's been 3 days and I'm panicking

This all started when I wanted to upgrade to a bigger memory card 1tb

Whenever I tried to follow processes online and on YouTube, the migration fails and does not working and keeps getting this error stating

"Unknown pkg1 version.
HOS version not supported!
Or emuMMC corrupt!

Trying backup...
Found pkg1 <''>.

Unknown pkg1 version.
HOS version not supported!
Or emuMMC corrupt!

Failed to launch HOS!

Press any key..."

So when I keep following other ways to migrate, I found out that the OFW is not available anymore and unable to boot normally, I tried to just press the power button to holding it for 60 seconds to holding the power button as well but the switch won't turn on, the one thing turning on is Hekate and the CFW on the old sd card, I saw post stating that autoboot could be turned on so I checked and I don't see the option and on the reboot option of Hekate, the OFW is now greyed out, please help me I'm panicking.
