Without reading every reply in this thread, I'd like to say that this is overly complicated (too many steps). I did something like this from the beginning, and using a magnet to boot is only ever needed ONCE.
Compiled my own flasher to use ntr_boot.firm and flashed my Ak2I
On the SD: ntr_boot.firm = safeb9sinstaller, boot.firm= Luma
also on the SD is the starter pack with extras (I prefer FBI to install stuff, and of course I include the DSP), Godmode9, Decrypt9WIP, and a couple of other things are already in luma/payload with buttons assigned, gm9 folder with scripts and support files (that can't be uploaded here), etc...
So on the target system, ntrboothax once, then power on while holding X and Godmode9 loads, and you can copy things over like this post says.
Personally, I'd rather use a PC when I can because I don't like to swap cards all day (remove the target to put mine in, then remove mine to put the target back in and save stuff from the ram drive, and I usually throw in a .cia or two that could NOT be done via ram drive), so I'd rather just drag&drop a pre-made folder I put together onto the person's card, then their system is hacked in what seems to be less than a minute, and I can send them on thier way.
