Hi everyone my 3DS XL is still bricked after tried unbricking with Arduino Uno.
I tried multiple setups:
1. With 74HC125 and 1117-3.3 for voltage converter and this LC Soft SD card module circuit (I created my own
http://www.element14.com/community/servlet/JiveServlet/download/40595-65625/lcsoft SD module.pdf).
Result: Sometimes detected, but with CID 0xFFFFFFFFFFFFFFFFF...
2. With CD4050BE and 1117-3.3 for voltage converter and this LC Soft SD card module circuit (I created my own
http://www.element14.com/community/servlet/JiveServlet/download/40595-65625/lcsoft SD module.pdf).
Result: Never detected. After unwiring my 3DS won't turn on at all. To turn it on I need to connect the charger and battery to my 3DS -> strange (battery voltage is 4.13v).
3. Wire it to SD adapter and connect it to Laptop SD card reader.
Result: Not detected at all.
4. Modified my Arduino Uno to work at 3.3V and wire it directly to 3DS with some capacitors and pull ups from
http://www.element14.com/community/servlet/JiveServlet/download/40595-65625/lcsoft SD module.pdf).
Result: Never detected.
Anyone can help me reviving my 3DS from death, and the battery problem? Thanks.
