Following these practices will help ensure your firmware update goes smoothly from start to finish.

Please refer to the soundcore installation guidelines:

• Keep the earbuds in the charging case and ensure the case is open.

• Make sure the earbuds have enough power (over 20%).

• Do not use the earbuds during the update.

• Try again if the update fails.

• Try using another device if possible.

• Do not update the firmware in areas with strong signal interference, such as dense Wi-Fi networks or cell phone towers. Move to a different location and try again.
