Advice on how to reset Flare to factory settings

After attempting firmware update, one of my flares won’t pair with the other for stereo sound. Any advice appreciated.

did you complete the firmware update via the app? I had one of my speakers not complete the firmware update and I had to do it a second time.

once the firmware update is done and your all set have one speaker connect to your phone, then on that speaker press and hold down the bluetooth button for 2 to 3 seconds and you will hear it double beep, go to the second speaker and press and hold the bluetooth button on that for 2 to 3 seconds and then wait as they should automatically pair together
