Thank you, that tells me what's wrong. Your NCSD header is screwed. Essentially you wiped the partition structure. It cannot find or mount CTRNAND, TWLN, TWLP, cannot mount your FIRM partitions (meaning you cannot install B9S), can't get your OTP, can't read your sector0x96, can't get your system keys, etc, etc, etc. Basically none of the tools will be able to do anything on a NAND in this condition. It's not a hardware failure though. And it can be fixed. What type of 3DS is this (new or old) and what region is it (usa, eur, jpn)?
