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.

Tutorial Updated

A definitive way to test if your Switch is patched or not (purchases after 07-2018)

This tutorial uses TegraRCM command line to send payloads to RCM enabled Switch.
Command line is used since it offers a more detailed explanation on what is going on.
So it is a definitive way to confirm if your Switch is patched or not without further questions.
This tutorial does not make any modification to your Switch console.

Requirement:
No Micro SD Card is required.
1. Any way of entering Recovery Mode. Please read here, https://gbatemp.net/threads/the-ultimate-list-of-mods-to-enter-rcm.502145/
2. biskeydump.bin payload(please get the latest version, as of 30th July 2019, the latest version is V9), can be downloaded from https://switchtools.sshnuke.net/
3. TegraRcm GUI, can be downloaded from https://github.com/eliboa/TegraRcmGUI/releases
4. USB C to USB A cable
5. A PC with USB port (Sorry I don't have Mac so I could not cover this area)

Step-by-Step (in total 7 steps):
1. put in your RCM Jig on the right joy con rail. Press and hold Vol+ then press the power button.
You should see a black/blank screen after you press the power button.
If you see a Nintendo logo, you can power off your console and try to adjust your RCM Jig position.

2. To install APX driver
2.1 Launch TegraRcm GUI, go to Settings tab, click on "Install Driver" button.

Confirm the driver installation.

2.2 For those having problems installing APX driver :
Install and launch Zadig. Plug your Switch in RCM mode, then select Options > List All Devices.
Select the APX device and check which driver is installed for this specific device. If libusbK is not the current driver, install it.

(This step is copied from https://gbatemp.net/threads/tegrarcmgui-simple-gui-for-tegrarcmsmash.503510/)

3. Plug in USB cable from your PC to Switch(in RCM).
Open TegraRcm GUI and you should see this window with "RCM OK".

Alternatively, you can use Device Manager to confirm if the APX device is recognized.

Now you can close the TegraRcm GUI application.

4. Copy biskeydump.bin to the TegraRcm GUI folder.

5. Open a command line and go to the TegraRcm GUI folder.

6. Run this on the command line

Code:

TegraRcmSmash.exe -w biskeydump.bin BOOT:0x0

7. Check the result
7.1 Switch accepts and executes payload, which mean your Switch is not patched.
Please refer to 0X7000

You will also see QR code on your Switch screen.

7.2 Switch accepts but does not executes payload, which means your Switch is patched.
