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.

This can be ignored now, I got it booting again using TegraGUI & then removed AutoRCM.

Now I just need to workout what to do with it going forward, stick on SX OS or change, I'm so far out of the loop its unreal.

Below was my issue:

Hi

I'm sure this has probably happened to someone else but i cant find anything clear on the subject.
So any help is greatly appreciated.

I have a Switch (not sure what OS its on officially), it was hacked using SX OS (again not sure what version)
However I don't have the dongle, So I believe the switch is stuck in auto RCM.

What do I need to do to recover it & get it working again..... other than another SX dongle.

Thanks

AutoRCM is a feature where the Switch goes to the RCM mode automatically by an intentional corruption of the BOOT0 partition.

I would recommend going for Atmosphere as SXOS does have no updates anymore :
