Tickets, activity logs, system data, etc. is ALL stored in the NAND partitions. The most that could be stored elsewhere would be the installation folders that I made sure to delete.
Then I don't have any ideas about the exact reason why you still hit even if you remained offline until restored your NAND backup and deleted game folder in Nintendo 3DS folder, maybe something else still stuck in somewhere else.
