I was updating the flashcart to 1.1 today. I put the flashcart back to 3DS after the updating. The build-in LED started to flash (1 second on, 1 second off) when I powered on 3DS (According to manual, it was 'chip error'). I still could enter mt card menu, but it said 'read card error' when I tried to select games. I tried several micro SD cards and 3DS roms (with or without sav files), still no luck. Any idea? Thank you.
