Hacking Homebrew on 3DS 6.1.0-6U

[Vinícius]

Hello, sorry for the bad English.

I recently bought a 3DS in 6.1.0-6U firmware. I've seen a lot of tutorials but none of the firmware that the console is on.

Is there any solution for me to unlock my 3DS in the current firmware or is it necessary to be between firmware 9.x and 11.x?
And if I need to, can I just upgrade to these firmware with a cartridge?

I recommend you use 3ds.guide to install B9S and Luma3DS using the browser method. That's what anybody here is likely to recommend.

Edit: To be clear, you don't need to update beforehand.
