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 have a dual-boot switch with cfw emunand. This switch has a chip installed and I bought it used, mentioning this incase its banned.

So I am on the newest atmosphere and FW version and I downloaded linkalho from the github

Now to be sure my cfw isnt immediately blocked I followed this advice from this thread.

The Real Jdbye said:
Yes but it's not needed anymore as Atmosphere has DNS blocking built in. It should be turned on by default. But to make sure it's enabled, copy system_settings.ini from config_templates to config (if it isn't already in config), edit it and remove the semicolon and space in front of this line "; enable_dns_mitm = u8!0x1"
Also copy exosphere.ini to config (if it isn't already there) and edit "blank_prodinfo_emummc=0" to "blank_prodinfo_emummc=1" for an extra layer of protection.
Then you are safe to use internet in homebrew.

But before I can even use it, I must link my local user to an nintendo online account. When I try to do this it says the following:

"An Error has occured. Please try again later. If the problem persists, please try perfoming a system update from system settings etc."

When I press details: "If this still does not fix the problem contact nintendo support"

Could it be that my switch is already banned or did I block so much that account linking wont even work anymore? I need this to get Quake 2 running for example

To Rephrase the question: Is there a safe way to link a nintendo online account on a CFW switch while blocking nintendos servers to not be banned while doing this?
