I left it in my bag and someone stole the card. Can I get my games back if I have another, formatted card with me? Or should I uninstall it and reinstall lumaCFW on the new card? thanks to anyone who can help
If you don't have FBI just follow https://3ds.guide/finalizing-setup. Then you can install cias using FBI or use FBI to install freeShop (see the OP of the Noob Paradise thread in the 3DS forum).
