JBL Flip 4 Software Update Instructions

JBL Flip 4 unboxed with its accessories laid out around this portable Bluetooth speaker.

Here’s our JBL Flip 4 software update instructions. This routine can take up to thirty minutes to finish, as affected by the speed of your WiFi connection. Plus, you can’t easily reverse this once done. That is, you won’t be able to return to any prior software version once you complete this speaker update. So, be sure that you indeed want the update before going ahead with it.

JBL Flip 4 Software Update Instructions: Preparation Steps

You’ll need and internet connection, a Bluetooth enabled mobile or desktop computer device, the JBL Connect app, and the JBL Flip 4 speaker itself.

So, connect your mobile device to the internet and install the JBL Connect app if you haven’t already.

Connect your speaker to household power, because we don’t want its battery going dead during the upgrade. A dying battery could corrupt the speaker’s memory, and so, brick the speaker, rendering it useless and not repairable.

So, to be safe, plug the speaker into AC power, using the included USB cable, as shown in the next picture.

Finally, connect the other end of the USB cord into a strong enough AC adapter, and plug that adapter into a working AC outlet.

Then, pair your mobile device with the speaker

You are now ready to begin the software update process.

But note that the speaker is still in the process of installing the new software for a few moments after the Restarting screen comes up. This screen warns that our speaker will restart automatically. Plus, it asks us not to unplug the speaker while it’s running the update. During this time, keep your speaker close to the mobile device running the app.

7. Wait for the JBL Flip 4 to Shut Off and then Power On Again

Watch the Power light on the speaker, as shown next. That lamp will soon go dark, as shown next, inside the green circle.

The speaker may or may not turn itself back on again. Ours did come back on by itself for this update. If yours did not, then go ahead with the next step (Step 8). But if yours did come back online though, then skip the next step and pick up with Step 9.

8. Power Up the JBL Flip 4

Press the dark Power button to turn the speaker ON again. The unit should again pair with your mobile device where you’re running the JBL Connect app. The Power button glows solid blue as your speaker successfully pairs again with your tablet or phone, as shown next.

With your speaker successfully paired to the JBL Connect app again, press the orange OK button, as pointed at by the dark blue arrow in the last screenshot.

The app then displays the JBL Flip 4 status screen once again. However, this time, see that there’s no longer the red dot on the Settings button, as shown next. This means that the software update succeeded and that the speaker is now running the current software version. In this case, it’s version 4.0.0.
