Nike is constantly seeking ways to improve the Nike+ FuelBand SE and first generation FuelBand experience. We occasionally update the device firmware to enable smarter analysis of your movement and a more accurate view of your activity.
If a firmware update is available, Nike+ Connect will present a notification with the firmware details after you plug in your device. Click Update within the notification to install the new firmware on your FuelBand.
Note: Due to a known issue we're working to resolve, some Nike+ FuelBand App users are receiving an in-app prompt to update their device firmware when their firmware is already current, and as a result cannot complete their sync attempts. We are working to resolve this issue. If you are experiencing this problem, please sync your FuelBand or FuelBand SE via your computer (using Nike+ Connect) rather than via your Nike+ FuelBand App. We appreciate your patience and hope to have this resolved soon.
