You seem to have missed on the new permanent emunand region free patch.l that was released about a week ago. Install a patched cia and done, no more freemultipatcher or ntr needed. With that you can finally drop rxtools for good as gba VC and ds cards also work with reinand while they don't on rxtools.

Just take ANY 3dsx you want and rename it to less.3dsx, reinand also has a 3dsx to boot. Still it makes way more sense to use ctrbootmanager, even with autoboot. That way you still have the option to boot other stuff without needing to shove around 3dsx or using homebrew launcher.

Still, this tutorial doesn't make that much sense. Why use a 2.1 lesshax payload when you can have a more stable 2.7 payload? Lesshax is outdated. It was fun while it lasted but it doesn't increase boot rate or whatever.
