I search everywhere on the internet about this topic and I cannot find anything talking about this, does someone know how can I turn it back to black?

Weird, does this mean it is the mario edition motherboard that someone has rehoused? That's the only switch that had the tablet as a separate colour, which was red. (except for the labcon switch but you had to win that one iirc)

I think the toolkit only works with controllers but I could be wrong, my switch died so I have no way to check.

a few time ago my switch bricked and when i rebuilt it (with a donnor nand) the colors of the unit turned red
and yea, joycon toolkit only works with the controllers

So just the nand huh? Weird that the colour would be stored on the nand, I guess it's easier for ninty cos they can just pop any board into the mario switch with just a standard motherboard.

Either that or maybe the tools you used to rebuild the nand someone affected the colour. I've never rebuilt a nand before so it's just guesswork as to where the switch colour is actually located. I'd assume the colour would be tied to the motherboard serial, but I guess not if you have a standard motherboard.

On the plus side, if you ever want a custom red switch shell, it'll match in software. Not exactly a solution but still.

Unless someone with more knowledge on this knows how to change it, I guess the only way to change it back is to get another nand, from a regular black switch and use that.

It's likely just a hex value somewhere in the firmware files. Needs in the haystack situation.

and how do i change it?
That I don't know. But it will change the checksum of the firmware files, which may or may not be problematic even if you succeed. Some consoles hash their firmware before installing it.

Yeah, sorry I can't be of more help. One thing you could try though is getting a NAND dump of another stock unit on the same firmware version, and comparing the two dumps in a hex editor. That might be a way to narrow things down to which .nca file needs opened and edited.
Both dumps would need to be formatted/initialized as stock first, though.

So, I found out that the colors are stored in the Prodinfo and are generated trough the device id

In prodinfo_gen source code the colors are generated by this code:

but I am a noob at C language and I dont understand it
