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.

Hacked switch often "locked in hibernate"(freezes) randomly after update

Hi.
So iv had my hacked switch for many years, worked flawlesly and no issues.
A few months ago I updated to 15.0.0 and AMS 1.4.0.
After doing this Iv had the anoying problem that 1-2 times a week the switch wil not wake from hibernation overnight when I press the home on the pro controller. The pro controller desperatly tries to connect and never stops trying. Normally it goes a few times and gives up, but in this state it can blink for hours, like it finds it but just cant connect.
I then go over to the switch, and pressing power, home or other buttons have no effect. I can hear the cooling fan spin so its on but does not react. I then have to hold the power button to shut it all off before using tegra to reboot with fusee.bin

Few key things:
Its on 100% battery, charging fine
No modchip
Sd card fat 32, no issues
No issues while gaming and using
No software running when not playing

Any idea what this "deep hibernate" is? Dident have any issues on previous ams or firmware.
