If Nike+ Connect displays a Code 12 message after you plug in your Nike+ FuelBand SE or first generation FuelBand, it means your device is no longer linked to NikePlus. You'll need to perform a factory reset in Nike+ Connect to resolve the problem.
If you're experiencing Code 12, try the troubleshooting steps below:
- In the Code 12 message box, click "Report." This provides Nike with important details about why you've experienced this issue. You will not receive a response to the report you submit. These reports are strictly for research and development purposes. To receive individual support, please contact us.
- Click "Reset", which will initiate a factory reset of your FuelBand. Please note that a factory reset removes all user data and other information from the FuelBand.
- If the factory reset cannot be completed on the first attempt, please retry two more times.
- If three or more factory reset attempts through Nike+ Connect fail to resolve the issue, please attempt an alternative FuelBand factory reset.
If you're unable to resolve Code 12, please contact us.
