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.

So I tried to setup a second SD card because Sig patches are not fixing my Tinfoil+ other certain titles not running after updating atmosphere/hekate.

And I got this error on Tegra RCM GUI: "
Error while injecting payload (RC=-2)RCM device disconnected
RCM Device detected
Invoking TegraRcmSmash.exe with args : "C:\Users\evanz\Desktop\hekate_ctcaer_6.0.3.bin"
Error while injecting payload (RC=-2)"

I believe the --2 refers to the second payload on my list which is hekate ...

So, I attempted to make sure the console was off and not just sitting in RCM mode and then took the SD card out and replaced it with my normal SD card that should be working.

But now it gives me the same error when trying to inject hekate into my old SD card, and it won't boot otherwise...

Did I corrupt my SD when I took it out?

Anyone know what common problems will throw this error and/or why I'm now getting the error on my working SD card (only certain titles and Tinfoil don't work but 60 games worked previously and now nothing works.)

I would greatly appreciate any help. I'm really struggling. I've updated the sig patches (prior to this problem) a million times and from 100% reputable sources such as gbatemp and https://wiidatabase.de/switch-downloads/hacks/signatur-patches/

and there's a github, i've tried them all ... but now I have a new problem.. ugh
