I am a Bit Lost Around Here [10.5 Homebrew Assistance]

Well, I'm doing my best to get into the hacking scene, but I need a wee bit of assistance which I can not find. I have an old 3DS on Ver. 10.5.0-30U and I am wondering what I can do (if I can even do it) to get this 3DS into the Homebrew Launcher. I have no way of entry besides browserhacks (to my knowledge, this is now broken). All I'm asking is if someone can point me into the right direction.

Long story short~
-Old 3DS
-10.5
-Homebrew
-heeeeeeelp ;~;

Thanks to everyone in advance that...
