Hacking Rosalina menu won't launch.

[Hydeo]

So I just factory reset a 3DS that I bought yesterday from a friend, after reading that I can do it if I have Luma 3ds, Godmod and everything else. I factory reseted it and now I can't access Rosalina Menu.
I'm doing the combo the right way, left bumper, down and select, but nothing happens. My 3DS updated to the 11.6, my Luma version is 7.1 and my Godmod9 is 1.1.8. I don't have a flashcard or a friend with another 3DS, so I hope i don't need to do everything from the scratch.
There's a easy way to fix it, or I'm just unlucky?

Ps: I was using another person thread, so I guess it's better to make this one, as it's nothing related to that one.

Rosalina menu is on luma 8.0+

Oh, that explains a lot. Thank you.
I used godmod9 to install FBI cia on H&S, so with that I installed all my homebrews, after that I reverted it back to normal.
So now I should update my Luma, right? I launched my Luma Updater, but it says that I need to update bootstrap, but I noticed something when entering Luma Updater, I have sighax, what does it mean? Can I follow the steps on 3ds.hacks to update B9S?
I'll probably do it later, as I want to play some games and this already stressed me out a lot. lol

What sighax is isn't important, although B9S is an implementation of it.

To update everything needed to get you on Luma 9.0:
Just download the current version of SafeBoot9StrapInstaller at https://github.com/d0k3/SafeB9SInstaller/releases and run it.
Then download the newest version of Luma from https://github.com/AuroraWright/Luma3DS/releases and put it on your SD card as boot.firm.
You might also want the current version of Luma Updater at https://github.com/KunoichiZ/lumaupdate/releases/ as old versions don't work anymore.
Then follow Finalizing Setup on 3ds.hacks.guide https://3ds.hacks.guide/finalizing-setup to get everything back on your home menu.
