JBL Xtreme 3 Firmware / Software Update Instructions

Here, we offer JBL Xtreme 3 firmware update instructions for this revised version of the Xtreme series power bank Bluetooth speaker. This update can take up to fifteen minutes depending on the speed of your internet connection. Plus, you cannot easily back it out. That is, you won’t be able to downgrade to the earlier firmware version once you complete this upgrade. So, be sure that you truly wish the upgrade, and that you’ve considering all its potential gotchas before going ahead with it.





Disclaimers for JBL Xtreme 3 Firmware Update

We were unable to update our JBL Xtreme 3 firmware when we received this speaker at the time of this writing.  Why?  Because the speaker already had the current version.  So, we borrowed some pictures below from the firmware updates we did on our JBL Charge 3 speaker.  We used pictures of the JBL Xtreme 3 speaker where we could though.  Indeed the firmware update processes are similar for both speakers.  Finally, if or when we receive an actual firmware update notification for our JBL Xtreme 3, we’ll update these photos to show the actual update in progress.

Prepare for JBL Xtreme 3 Firmware Update

Get Connected to the Internet

You’ll need and internet connection, a Bluetooth enabled mobile or desktop computer device, and the JBL Connect Plus (Connect+) app, as well as the JBL Xtreme 3 speaker itself.

Install the Connect App

So, log your mobile device into the internet and install the Connect app if you haven’t already.

Plug your JBL Xtreme 3 into AC Power

Connect your speaker to AC power. Why? Because we don’t want its battery going dead during the firmware update. This accident could leave corrupted firmware in the speaker’s memory with no way to refresh it, and thus, render the speaker useless and not repairable.





Pair your Speaker with your Internet Connected Mobile Device

Then, pair your phone or tablet with the speaker.

You are now ready to begin the firmware updating process on that JBL Bluetooth speaker.

JBL Xtreme 3 Firmware Update Instructions

1. Find the JBL Connect App on your Mobile Device

We found ours on the fourth home page in our Apple iPad Air, as shown next.

2. Run the JBL Connect App

The app takes a few seconds to show you some nifty animations when you first start it. But then it finds your paired JBL Xtreme 3 speaker and shows you its status screen, as shown next.

Note the explanation point inside the orange circle in the top right corner of the speaker’s picture, as pointed at by the dark green arrow. This means that there are important messages about this speaker pending for your to read and act upon.

Note that if there are no current messages or firmware updates available for this particular wireless speaker, then you will see no explanation point.  Also note that the above picture, while it applies to the Charge 3 speaker, is similar to what you’d see with the JBL Xtreme 3.





3. Tap the Orange Circled Explanation Point (!)

Tapping the Important Messages (!) circle brings up the first IMPORTANT NOTICE screen about the available firmware upgrade, as shown next.

Touching the INSTALL button brings up the Upgrade Speaker screen as shown next.

We connected our JBL to an AC outlet in the preliminary firmware update steps above, as shown in the next pictures.

Next, go back to the JBL Connect app running on your mobile device, and tap the OK button. See this button in the last screenshot picture above.

8a. The JBL Xtreme 3 Firmware Update Process Begins

Copying the file from the internet to the speaker is the slowest part of the firmware upgrade process. But as shown in these screenshots, the JBL Connect app shows you a progress pie-chart picture, that gradually becomes more orange as the firmware file transfer proceeds.

The JBL Xtreme 3 may or may not turn itself back on again after the upgrade. Ours did not. So if, like ours, yours did not come back up, then go ahead with the next step (Step 10). But if yours did come back online though, then skip Step 10 and pick up with Step 11.

10. Power On the JBL Xtreme 3

Press the dark Power button to turn the speaker on again. Then it should again pair with your mobile device where you’re running the JBL Connect app. The Bluetooth button turns solid white when your speaker has successfully paired again with your tablet or phone, as shown next.

11. Press the Done Button in the App

With your JBL Xtreme 3 successfully paired to the JBL Connect app again, press the green Done button in the Connect app, as shown above.

The app then displays the JBL Xtreme 3 speaker status screen once again. However, this time, note that there’s not any upgrade button, as shown next. This means that the firmware update succeeded and that the speaker is now running the current firmware version.
