The JBL Connect app, displaying the Boombox speaker and its battery status.
Here, we offer JBL Boombox firmware update instructions for this awesome sounding power bank BT speaker. But be aware that this upgrade can take up to fifteen minutes depending on the speed of your internet connection. Plus, you cannot easily reverse it. So you won’t be able to downgrade to the earlier version once you complete this upgrade. Thus, be sure that you truly wish the upgrade, considering all its potential gotchas before proceeding.
You’ll need and internet connection and a Bluetooth source device. You also need the latest version of the JBL Connect app, and the JBL Boombox itself.
So, get on the internet on your mobile device. Then install the Connect app if you haven’t already.
Connect your Boombox to AC power. Why? Because we don’t want its internal battery going dead during the upgrade. Such a mishap could leave corrupted firmware in the speaker’s memory, and thus, render it useless and not repairable.
Then, pair your phone or tablet with the Boombox JBL speaker.
You are now ready to begin the firmware updating process on that JBL Bluetooth speaker.
First of all, we find ours on the fourth home page in our Apple iPad Air.
The app takes a few seconds to start. And while it does so, it shows you some nifty animations. It also searches for eligible connected JBL speakers during this time.
But then it finds your paired JBL Boombox speaker and shows you its status screen, as shown next.
Note the red dot at the top right edge of the speaker’s Settings gear control. The presence of this dot means that there are important messages to read.
Note that no read dot means that there are no current messages or firmware updates for this speaker.
Tapping the Settings button New Firmware Version screen, as shown next.
This screen gives version number details about the available firmware update.
Touching this link brings up a screen that gives details about the enhancements made to the new firmware version.
In our case here, it tells us that in version 2.9.0.0, there are just minor but fixes.
Tap the X button in the top right corner of the Firmware Details page. This then takes us back to the New Firmware Screen.
Find the Upgrade button, as pointed at by the green arrow in the last picture above. Then touch it.
Now if you have not yet plugged your JBL Boombox into AC power, you will get the following screen.
Note that the I Followed the Instructions button is gray. Indeed it will remain that way until you connect your speaker to AC power.
Then, once you make that connection, the screen changes to the following.
Note that the I Followed the Instructions button is no longer gray. It has in fact, turned orange, meaning that you can tap it now to continue with the firmware update.
Find the I Followed the Instructions button, in the center of the page.
When you tap this, the firmware update begins, and the screen changes to the Upgrading… page, as shown next.
The page that shows next displays firmware update progress.
This screens keep showing as the percentage complete of the operation counts up to 100.
Now this was probably around four minutes into the firmware update at this point in the process.
The next screen shows that the firmware file transfer is complete (100 percent). So the speaker now restarts.
After some seconds, the Connect app notifies you that the JBL Boombox firmware update is now complete.
You should see this happen while the Restarting screen displays on your mobile device, as shown next.
Watch the power light on the speaker, as shown in the last picture.
Eventually it will go dark, as shown.
Now the Boombox may or may not turn itself back on again after the upgrade. Ours did come back on. But if yours did not come back up, then press the Power button to manually turn it on.
The app then copies and installs the upgrade file. After that, the speaker comes on again and you get the Upgrade Successful screen.
With your Boombox successfully pairing to the JBL Connect app again, press the orange OK button on the screen.
The app then displays the JBL Boombox speaker home screen once again. But this time, note that there’s no longer the red dot. So this means that the firmware update worked. Also, the speaker is now running the current firmware version.
Finally, your firmware firmware is now up to date on your JBL Boombox Bluetooth speaker.
