Several things...
This question specifically says NOT Switch System Firmware but you either ignored that or forgot that 6.1 was a Switch System Firmware. I need the lowest SX Version you used offline/online. Secondly...Lowest SX Version used when Online/Offline (NOT Switch System Firmware)? 6.1.0
Clearly you did not stay offline with your emuNAND partition because not only did you go online to activate your SX OS license but you went online with .NSP files installed. Because of this, I changed your answers from using a clean hack-free NAND and using SX OS emuNAND to not because you used emuNAND incorrectly.Did you restore a clean hack-free NAND before going online? Y
Did you make an SX OS EmuNAND with a clean hack-free NAND then stay offline with it? Y
Did you connect to the Internet with SX OS and/or to activate the license? Y
Did you connect to the Internet w/ any .NSP installed? Y on emunand
