You can get close, a factory reset will make it appear to be factory fresh but there will still be traces left over. You're supposed to be able to create a vanilla NAND with ChoiDujour using only a couple of things from your existing NAND, that should have no traces of homebrew/CFW, but ChoiDujour might leave its own traces.I have several NSP Games on my Switch.
Is it possible to do a Nand backup and Clear this Nand to Stock (That means that it is like i turn on the Switch first time)
EmuNAND is just a copy of your SysNAND; if the SysNAND is already tainted, EmuNAND won't save you from a ban.But when Emunand is released, then i think it would gives you a way to create a Stock nand from your Binarys.
LOL ikrEmuNAND is just a copy of your SysNAND; if the SysNAND is already tainted, EmuNAND won't save you from a ban.
Not true. That doesnt delete telemetry.If you delete all system & user save data manually (with hacdiskmount or something) that would pretty much get rid of all traces of cfw
