You fucking idiot, read this whole thing. I don't care about your short attention span, read this right now and realize how much of a moron you are, you fucking idiot.

Here are all of the occasions to get a CFW on your 3DS that you have missed:
>9.2
Yes, this is the first one. Not 4.x, Gateway's shit and you had no reason to stay on 4.x unless you didn't want to play with your 3DS in 2013 and 2014.
However, in early 2015, when 9.2 was one of the latest system versions, you could downgrade to 4.x to install an unstable and free CFW. And after only a few months, an actual, free CFW was released: rxTools. It didn't allow you to pirate at first, but that came soon enough. Meanwhile, it allowed you to update from 9.2 WITHOUT losing its benefits and gaining everything else. But you idiots couldn't inform yourselves properly, no! Lurking the usual places (like GBAtemp or 3dbrew) or even >>>/vg/hbg/ (formerly /gwg/) was too hard for you fucking idiots. You feel this stupid need to be dumb and not even read what the system updates do to your console.
It's even worse, since the easy browser entrypoint on 9.2 actually became popular at the time. And when the next update came out, you had no reason to update. NO REASON. And yet you did. Because you couldn't read two sentences about it.
So you heard all of the /vp/ shitposters saying stupid shit like "yeah you need to go to 9.5 the pokemon cheat still works xDDDD". And while that's true, updating from 9.2 makes you lose what made 9.2 good in the first place: allowing you to control everything.

>10.7
If you aren't above 10.7, you can still downgrade to 9.2. Oh, and we got arm9loaderhax and a bunch of other cool stuff in the meanwhile. But you're a fucking idiot, so you updated past 10.7 too.
You fucking idiot.
