JBL Flip 6 Firmware Update Instructions

Here’s our JBL Flip 6 firmware update instructions.  This routine can take five to ten minutes to finish, depending on the speed of your WiFi connection and how fast your mobile device is.  Note though that you can’t reverse this once done.  That is, you won’t be able to return to any prior firmware version once you complete this speaker update.  So, be sure that you indeed want the update before going ahead with it.

JBL Flip 6 Firmware Update Instructions: Preparation Steps

You’ll need and internet connection, a Bluetooth enabled mobile or desktop computer device, the JBL Portable app, and the JBL Flip 6 speaker itself.

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

As a precaution, we recommend that you connect your speaker to household power, because we don’t want its battery going dead during the firmware update.  A dying battery could corrupt the speaker’s memory, and so, brick the speaker. This could leave 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-C cord into a strong enough AC power adapter, and plug that adapter into a working AC outlet.

Then, pair your mobile device with the speaker

But then it finds your paired JBL Flip 6 BT speaker and shows you its status screen, as pictured next.

Note the presence of the Software update available link near the top of the speaker’s home page, as pointed at by the blue arrow next.  This means that a firmware update is available for this speaker.  But if no newer firmware version has yet been released, this button does not appear here.

Now this screen gives details about the available firmware update.  In our case here, it suggests the Flip 6 upgrade to firmware version 0.6.4.0.





4. Tap the Orange Update Button to Continue with the JBL Flip 6 Firmware Update 

If your speaker battery has enough charge, and / or you connected it to an external power source as instructed to above, then the firmware update process starts.

But if your battery is low and you’ve not yet connected your JBL Flip 6 to power, you will be asked to do so at this time.  Then if you are asked, plug in the speaker, and follow any screen prompts to begin the update.

5. The Firmware Update Process on JBL Flip 6 Begins

The update then starts.  So the Portable app displays a progress screen as shown next, to let you know how far along the update is.

At this point, the speaker is installing the new firmware into its primary memory.  This takes roughly two minutes.

The speaker will restart automatically when it finishes updating.

6. Wait for the Speaker to Shut Off and Power On Again

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

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 7).  But if yours did come back online though, then skip Step 7 and pick up with Step 8.

7. Power On the JBL Flip 6

Next, 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 Portable app.  The Pairing button glows solid white  as your speaker successfully pairs again with your tablet or phone, as we see next.

Then meanwhile, back in the Portable App, the Update Successful appears when the app receives confirmation from the speaker that the firmware upgrade completed without errors, as shown next.

8. Press the Let’s Party Button

With your speaker successfully paired to the JBL Portable app again, press the orange Let’s Party button, as pointed at by the blue arrow in the last screenshot.

The app then displays the JBL Flip 6 home screen once again.  But now, notice that the Software Update Available bar is now gone, as we see next.
