Try updating the 3DS firmware to 11.9 either through Recovery Mode or System Settings → Other Settings → System Update. If updating doesn't go through, disassemble the o3DS and reseat the WiFi module. The o3DS / o2DS / o3DSXL are known to have boot issues if this is loose or unconnected.Yes. I did manage to get the system to boot to homescreen however. Is it safe to update to try and see if that improves things?
