Hacking Bootrom error after hardmod.

[ArmoredGuns1]

I attempted to do a hardmod on a New3DS, it read the NAND.img right. After following Plai's guide steps, I wrote a new NAND file. After that, it shows the bootrom error and it won't recognize after putting it in the SD adapter. What could've gone wrong and how could I fix it? I still have the original NAND.img file. Help is immensely appreciated!

This is CLK.

Dat0 and CMD

Ground (the black cable)

The SD card.

Whenever I try to read or write, win32diskmanager says Cyclic Redundancy Error. Please help

Maybe the NAND dump was bad? Did you verify the NAND dump prior to re-flashing?

What reader are you using?
I had success with the targus sd/microsd reader that walmart sells
