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.

Hey Guys,
I just wanted to ask if there is a way to change the theme without theme installer, since its crashing on sx 3.04(10.1.0).

Thanks

Did you try installing multiple themes before?It happened to me like 5 minutes ago. The "fix" I did was, deleting the systemData folder from the themes folder and extracting the home them again. It works again for me.

You need to delete your lock screen theme folder from your sd card> sxos/patches/themeinstaller... then reinstall your themes but make sure you leave the lock screen theme out.

Theme installer has been updated to support the latest firmware so it might work I’ve not tried it myself. I still don’t think the lock screen theme will work because it’s the ips patches that are not working nothing to do with the themes being compatible on the latest firmware but like I say give it ago anyway, it’s worth a try.
