Help unmodding my Switch (no NAND backup)

[lysform]

I have a Switch v1 without emuMMC and no NAND backup (yeah, I know I'm dumb). Since it was modded, it hasn’t been connected to the internet. What’s the safest way to try and make it secure for online use? (At least the solution with the highest chance of success). Thanks!

So there's no workaround it...

Nope if you don't have a CLEAN Sysnand OFW then you can't go online, if you used Sysnand CFW with NSP then it is dirty.

you need a nand backup to be completely safe during the process. but as you said you dont have one. If you are reselling this switch you are talking about. If you used any nsps on sysnand, for whatever reasons even if its just homebrew apps then your nand is essentially marked for banning as soon as you connect to nintendos servers nothing can fix it, no factory reset. only thing that can is restoring a backup before you modded the switch.

if you used a emunand however you are in a much better space and there are plenty of guides on the process

only thing that can is restoring a clean backup before you modded the switch and after the last time it was online, if ever.
