Service Error on GoBe U: What It Means and How to Fix It

If your GoBe U smart band displays a Service Error, don’t worry — in most cases, the issue can be resolved with a few simple steps. This article explains what the error means and how to perform a factory reset if needed.

What Is a Service Error?

When a Service Error occurs, GoBe U enters a special mode to signal that something went wrong in the system. In this mode:

• The band displays a solid red backlight at 30% brightness

• It emits short red flashes at 100% brightness

• The number of flashes corresponds to the error code

Error codes and meanings:

• 01 – Memory error

• 02 – Functional firmware won’t launch

• 03 – Internal system error

• 04 – System bus error

• 05 / 06 – Communication controller error

Important: Data Loss Warning

To resolve the error, you may need to perform a factory reset. Please note: any unsaved data (e.g., recent steps or calorie intake) may be lost during this process.

Special Case: SERVICE 02

If your device shows SERVICE 02, you might not need a reset. If the band successfully connects to the HEALBE app, the app will prompt a firmware update automatically. Only if this update fails should you proceed with a factory reset.

How to Perform a Factory Reset

Follow these steps:

1. Turn off the band by pressing and holding the control button for 3 seconds

2. Press and hold the button again for 7 seconds, then release

3. Open the HEALBE app and reconnect the band

4. Set a new PIN code and complete the firmware update

If these steps don’t work or you’re unsure how to proceed, don’t hesitate to contact HEALBE Customer Care. We’re here to help!
