Hacking How should i hard reset my 3DS

[Urataros07]

I have a New 2DS XL that i returned to stock firmware 11.6 after i hacked it with the 3DS new gold plus flash card. I want to hard reset it to get rid of my NNID,use the 3DS normally and hack it once again in the future

What should i do

If you just do a normal format, then it will delete all the data. It won't mess with any CFW you may have.
