I'm thinking of downgrading a 10.3 unit with an NNID tied to it and doing CFW with unlinked nands without losing any data. Here's my though process: 1. Downgrade to 9.2 2. Downgrade MSET, that way NNID settings won't be present when I unlink 3. Factory reset to unlink My question would be, would this even work? Would I still get that NNID error on emunand if I do this? I'm just trying to think about not losing all other data, hopefully this works.
