This video explains the firmware update process for the JBL Flip4 wireless Bluetooth speaker. The update of the firmware / software on the speaker requires an Android phone or an iPhone with the JBL Connect app installed. The app can be found in the Google Play Store or the App Store. Once the app identifies the speaker, check for the little red dot on the settings icon at the bottom of the screen. This indicates that there is an update available. The update process takes about 20minutes. Make sure not to close the app at any time during the update. Otherwise the speaker may not be functional afterwards! Wait for the speaker to reset and restart on its own. Then the speaker and the phone can be used again.
