Works great for me.
Also, for the ones who have CtrBootManager (or similar) as their boot.3dsx and who still want this .cia to boot the homebrew launcher without keeping a key pressed, just open the payload (I used the one it automatically downloaded) with a text editor (I used Notepad++), look for "boot.3dsx" and replace that with any string
of the same length, like "bohb.3dsx". Well, actually I didn't try with a different length but I feel like it wouldn't be a good idea. Then, of course, your .3dsx file that correspond to the homebrew launcher should be named the same way, "bohb.3dsx" in my example.
Now your 3DS autoboots on boot.3dsx which is CtrBootManager, and this .cia launches bohb.3dsx (or whatever you named it) which is the homebrew launcher
