I made a backup of my switch's nand but I'm unsure if it I booted into cfw before I did a backup. I have never logged online or made a wifi connection.Does booting into cfw (it was reinx) made the Nand dirty (therefore unsafe to use online). Is there any way of being able to tell if my Nand is dirty that I backed up. Maybe if I restore it and somehow check the logs or maybe clear the logs before going online since I have not been online yet?
