Got to the step where I rebooted my o3ds w/o the sd card but once the homescreen loads up there is nothing that pops up whereby I can configure the ctrnand based luma installation. i.e. can't perform step 21)
Use the (A) button and the D-Pad to turn on the following:

• “Show NAND or user string in System Setting"

I redid this section multiple times but I always end up with the same problem.

Any guidance would be greatly appreciated.

 

Yea so I've repeated the steps multiple times, making sure I didn't make a mistake/missed a step, to no avail. I still keep getting the same result when I reboot to the homescreen. Any other advice or is there a step I can backtrack too and redo a larger portion of the installation?

 

I can confirm with certainty that i selected the sysnand backup/restore option and not emunand

 

Are you holding select when turning the 3DS on?
You don't change these settings from the home menu, you hold select on boot and go directly to the Luma Config screen.
