Detailed instructions on how to update the firmware of your Apollo Bold.

To better assist you to update the firmware of Apollo Bold, we provide you with detailed instructions.



a) Before updating, you need to take out one of the earbuds and make sure the other earbud is placed in the charging case. Start to update the first earbud. When the update is finished, put it into the charging case and take out the other earbud to update the firmware.

b) If you cannot connect the APP after updating, please delete the connected Bluetooth name on the Bluetooth setting interface, and then search again to connect.


Here is how to update:

*Download the ‘Tronsmart’ APP on APP Store (IOS) or Google Play Store (Android). 

Method 1: (For IOS & Android)

First, you should download the firmware and wait for the installation to be completed. During the installation process, it’ll disconnect your earbuds and then reconnect automatically. No action is needed until the installation is done.


After completing the update of one of the earbuds, update the other earbud in the same way. Make sure that both earbuds are successfully updated separately.

When two earbuds are successfully updated separately, you’re all set to enjoy the music with your updated Apollo Bold.
