Firmware Update Troubleshooting

If you experience trouble while attempting a manual firmware update, try the following:

• Ensure your ring's battery level is at least 30% when attempting to update your firmware
• Ensure your ring is connected throughout the updating process — don’t close the app or toggle your Bluetooth on/off while the update is taking place
• Keep your device's screen unlocked during the update to prevent potential interruptions
• Make sure your device’s operating system is up to date. You can check this by opening your phone's Settings
• Restart your phone
• Attempt the firmware update in a room where the signal interference is low (no other devices nearby)
• If you're unable to see the firmware update, uninstall and reinstall the Oura App, then check the home screen for a firmware update message
• Attempt the firmware update through a different device (e.g., a tablet)

If none of the above steps help with the firmware issue, please try uninstalling and reinstalling Oura on your phone:

1. Complete a data backup by tapping the menu in the upper left-hand corner of the home screen > Settings > Back up all data
2. Delete the Oura App from your device
3. Reinstall the Oura App
4. Place your ring on the charger, ensuring the small light on the front of the charger appears
5. Go to your device's Bluetooth settings
6. Locate your ring in the list of connected Bluetooth devices (look for "Oura" in the name) and tap the icon to the right to unpair/forget the device
7. Unpair other connected Bluetooth devices to eliminate potential interference with the Bluetooth signal
8. Make sure the ring is on the charger and charger is plugged in
9. Relaunch the Oura App
10. Follow the in-app onboarding flow to set up your ring
