Ok I've been reading a lot of conflicting info about bans. The biggest conflict I've noticed is to do with logs and clean nand.
Clean nand would mean a nand that is backed up, before touching online functionality and custom firmware.
Logs would be the data sent to Nintendo and stored locally on the switch.
Now I have a hypothetical scenario:
1. Clean nand on 3.0 made. (connected to Nintendo network prior)
2. Upgrade to 8.x via cfw.
3. Use cfw but don't go online.
4. Restore clean nand, and use it to go online.
This scenario is fine, but now:
5. Want to use cfw. Backup nand before using cfw?
The main thing that puzzles me is if we use stock/clean nand online, then use cfw, then restore clean nand to go online, isn't it the same as clearing the logs? Or same as having modified logs as the last time the switch connects online, its logs will not be matched with the clean nand backup.
Or do we need to make a clean nand backup everytime prior to using cfw?
