How would I go about factory resetting my EmuNAND? Is it possible to do without wiping the contents of the SD Card? If I set up EmuNAND on a spare SD Card, can I factory reset it and not lose any SysNAND data?
Same as sysnand I do believe. Personal suggestion, backup NAND between updates. Both preferably or if you refuse to ever touch the sys in any way just emunand. I have an emu backup of 9.4 and 9.5 right now. Didn't know I could do it on 9.2 and 9.3 was gone before I got a gateway. That way you could just reflash the nand in it's earliest state.
