ohhh, i thought sysnand CFW is like a copy of OFW, and emunand is copy of sysnand CFW.
this was my thinking of the situation. if i have unmodded OFW 14.0.0 then modded it therefor i have
OFW - 14.0.0 (can only be update to wifi)
sysnand - 14.0.0( can be updated to daybreak)
emunand-14.0.0(can be updated to day break)
Technically speaking, you have 4 possible ways to boot, it's like a lattice
| SYSNAND (OFW on eMMC) | EMUNAND (CFW on SD card) |
| No Mods (No Atmo) | A | B |
| With Mods (With Atmo) | C | D |
A) is how your console boots stock with no hacks.
B) is how your console boots if you haven't modded anything but make a copy of your sysnand to your SD card called emuMMC or emuNAND
C) is how people get banned from Nintendo servers, by booting to official firmware, making mods without masking their console ID, and then their console tells on them to Nintendo's servers.
D) is how you do everything Nintendo doesn't want you to do, but you also should mask your console ID in this version, because otherwise it is an exact copy of your OFW that is on your sysNAND, and can get you banned as well.
In other words, if you're running mods, mask your console ID, regardless of which system you boot into.
