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.

I'm hoping to get some help with this. My switch is running SX OS with auto rcm. I can get the machine to boot with a payload injection via PC but the screen lights but does not display anything. Once the system is running you can touch the screen and hear that it is working by the sounds but there is no display. If you put it in to it's dock it works fine.
I've been scouring online to find a answer but nothing seems to work.
Hoping someone on here can help
Thanks

Hmm it sounds like a hardware fault since it works docked. The back light and touch work, so I guess the LCD itself could be toast or the ribbon cable / connector to the LCD. If you look inside maybe you see something that doesn't look right.

I've looked at the ribbon connector and taken it out and refitted it but to no avail. I've just ordered a replacement screen and digitizer and will see what happens with them replaced. thanks for the response
