    I've recently set up Arm9loaderhax, and it works fine. Boots to Emunand by default and Sysnand if I hold R (Just a black screen if I hold L supposedly that's supposed to do something to do with a 9.0 sysnand but it's probably not relevant to me whatever it is)

    I've downloaded Decrypt9 from

    And ctrboot manager from

    From what I can gather I basically need to set up the new ctr boot manager, and then set it up to boot decrypt9.bin if I hold start or whatever.

    The only problem seems to be that when I copy arm9loaderhax.bin to the SD (Overwriting my current one), the 3ds won't boot at all.

    There doesn't seem to be any real guide to help set this up, could anyone help?

    Your original arm9loaderhax.bin (which, I assume is from AuReiNand?) is required to boot into your CFW. You're replacing your CFW with a boot manager that has nothing to boot into.

    Instead of replacing your arm9loaderhax.bin, rename it first to AuReiNand.bin (or whatever), then copy over the new arm9loaderhax.bin (from CtrBootManager9) and a9lh.cfg. a9lh.cfg is where the boot options are configured, the default is a good example file. Make sure its first entry is pointing to your CFW's .bin file that you named earlier.
