I have a Switch here that has never been online, but has ran CFW and Homebrew.
Is there a way to clean the system/NAND so that I can go online with it on OFW without getting banned?
I do not have a eMMC/NAND backup for this system to restore it to it's original state before the CFW/Hombrew.
Stuff like cleaning out logs and the such could help perhaps, if there are tools for that?
I think haku33 might do what you need
