I'm not sure what you're describing, but you need to setup an emuNAND properly before you can launch an emuNAND properly.
I didn't setup an emuNAND.
I went to the "Launch" menu in hekate and selected the "CFW (EMUNAND)" option.
I think that, since I didn't have an emuNAND prepared, it defaulted to launching "CFW (SYSNAND)", which kinda sucks.
Also, emuMMC is not the same as emuNAND, is it? Because I created one as a SD File, but it doesn't boot after being selected.
Doing a factory reset will not clean a dirty NAND. If you are paranoid, you can restore your clean NAND backup to your sysNAND, but it's likely unnecessary.
Okay, thanks. And if I did restore the NAND backup, which one should I use? The BOOT0 & BOOT1 one, or the RAW GPP? Better yet, which are the steps to restore a NAND? The guide doesn't touch on that.
