I have a N3DSXL and when i start Safe A9LH installer, press selec it says that stage payload_stage1.bin is missing or exceeds maximum size.I tried replacing it but it still doesnt work.I used Plialtec's and Hyortesu's guide.
the payloads go into the a9lh folder.
you should READ CAREFULLY.
I figured it out, but thanks anyway!
