FIXONICBefore you begin
If your cartridge reader is not working on your original Nintendo 3DS model, use this guide to replace the cartridge reader (also known as a Game reader). The cartridge reader, when working, sends the game info from the reader to the main system, which allows gameplay by the user on the 3DS. Before attempting to use this guide to repair the 3DS, inspect the inside of the cartridge reader or the outside of the game cartridge for any built-up debris that may cause reading problems. Dust buildup can cause issues, but it can be resolved by using a dust blower or a small brush to clear it out. Before beginning, ensure that your device is powered off and disconnected from all external power sources. Recommended skills: should have a good understanding of soldering, as the cartridge reader needs to be soldered to the motherboard. Once completed, you will be able to get back to enjoying playing your games on the go!
