I hear too much homebrew will make you blind and give you hairy palms.
Yeah man homebrew is dangerous it can turn your 3DS into a cat, it might even try to live in your house so watch out.
And this is exactly the reason why idiots will post stupid questions and spread rumors.
Due to fools "sarcastically" posting shit.
Hate it when noobs ask stupid shit?
Stop replying stupid shit!
You prob just could have talked Chinese to him
Edit: Some parents don't even know how to format an SD card :/
This is exactly the case of most parents (of the age of 40 and older) and old people.
They know nothing about technology and people take advantage of that, especially sellers as they come up with stupid ways to sell them unneeded things.
The amount of times I heard people saying "yeh the seller said I should purchase this and take a subscription to it, as it keeps me computer safe"
"old" people have access to the web as well.
And when they start surfing, they will take 99.9% serious of what is posted online, just like noobs.
If idiots post idiotic things online or spread rumors (like in the early 3DS days that using a DS flashcard would brick the 3DS...) those two groups will believe it.
They tell their relatives and friends in the way of "I heard or seen that on the internet, so it must be true!"
People get upset about noobs asking the same question all over again.
And when those people will post "sarcastic" comments about it, the noobs won't learn and those people would just be creating a bigger problem.
As for OP.
Homebrew is completely safe.
The worst it can do is crash or freeze your 3DS.
Like people said before.
Just don't go downgrade.
