Hacking Luma 3ds won't update

[delgaucho]

i tried to update luma (from a9lh to B9s) by following this guide :https://3ds.hacks.guide/a9lh-to-b9s.html
A this point
Section II - Installing boot9strap
Boot your device while holding (Start) to launch SafeB9SInstaller
I have a problem:
I launch the hemebrew menu,not the safeb9sinstaller.
Have you guys have a fix?

Copy the SafeB9SInstaller.bin to /luma/payloads, re-insert the sd card to the 3ds and hold START and then power it on. That should solve your problem. The homebrew menu is only accessible in the 3ds "os". Not while you power on that thing. Otherwise a video what you do would be nice.

Or copy the installer to the root of your sd card and rename it to arm9loaderhax.bin. This should trigger automatically the installer when you turn on the console.
