Please follow the instruction below.
- Power off and restart the headphones.
- Set off the bluetooth of your smartphone and on again.
- Un install the app and re download the app.
- Try the firmware update again.
The light blinking means in the update mode.
BLE (Bluetooth data connection) will resume the connection after the restart automatically, even though the name does not appear in the list, nor reject the manual paring.
Music or the beep sound will not work until the update completed.
If it happens again, please retry the same process.
