How to Update JBL Charge 3 Firmware

Here, we show how to update JBL Charge 3 firmware for this popular Bluetooth speaker. This update can take up to thirty minutes depending on the speed of your internet connection. Plus, you cannot easily undo the update. So you won’t be able to return to the prior firmware version once you complete this software upgrade. So, be sure that you indeed want the update and have ruled out any possible problems with it before proceeding.

How to Update JBL Charge 3 Firmware: Preparation

You’ll need the following…

    1. An internet connection.
    2. A Bluetooth mobile device.
    3. The JBL Connect app.
    4. The JBL Charge 3 itself.

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

Connect your JBL Charge 3 to AC power. Why? Because we don’t want its battery power bank going dead during the update. This mishap could leave a corrupt version of the firmware in the speaker’s memory. Then this might brick the speaker, rendering it useless and not repairable.

Then, pair your mobile device with the JBL Charge 3 Bluetooth speaker.

You are now ready to begin the firmware update process.

How to Update JBL Charge 3 Firmware, Step by Step

1. Find the JBL Connect App on your Mobile Device

We found ours on the fourth home page on an Apple iPad Air.

2. Run the JBL Connect App

Then the app takes a few seconds to show you some pretty animations when you first start it. But then it finds your paired JBL Charge 3 and displays for you its status screen.

Note the explanation point inside the orange circle in the top right corner of the speaker’s picture. This means that there are important messages about this speaker pending for you to act on.

Note that if there are no messages or firmware updates, then you will see no explanation point. Note that you can’t update the speaker unless this app invites you to do so.





3. Tap the Orange Circled Explanation Point (!)  to Continue with How to Update JBL Charge 3 Firmware

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

This screen gives details about the available firmware update. Here, it tells us that we need this upgrade to enable JBL Connect+ functionality on our speaker. Specifically, this update allows it to connect into a group of up to a hundred JBL Connect+ compatible speakers. So you might want this for blanketing a large area with music for dancing and partying.

4. Flick to the Left to See the Next IMPORTANT NOTICE Page

Then this page warns that you cannot undo the update.  It says that once done, this software upgrade is permanent.

Furthermore, after this upgrade, our speaker will no longer connect with older models. So you will lose connectivity with JBL Flip 3, JBL Pulse 2, JBL Xtreme, JBL Boost, and Cinema 5B450.

5. Flick Once More to the Left to See the Next IMPORTANT NOTICE Page

Another left flick brings up the JBL Charge 3 firmware update confirmation prompt screen.

6. Tap the INSTALL Button to Continue with How to Update JBL Charge 3 Firmware 

Touching the INSTALL button brings up the   Upgrade Speaker   screen.

Then we connected our speaker into an AC outlet via the included power adapter and cable.

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

8a. JBL Charge 3 Firmware Update Begins

Copying the file from the internet to the speaker is the slowest part of the firmware upgrade process. But these screenshots show the progress pie-chart picture.  The “pie” gradually fills in with more orange as the firmware file transfer proceeds.

But note that the JBL Charge 3 is still upgrading after you first see this green and white page. This can last for up to a minute. Thus, this screen warns that our speaker will restart automatically when it installs the update. Further, the app asks us not to unplug the speaker during this time.

9. Wait for the JBL Charge 3 to Shut Off

Watch the Power light on the speaker, as shown next. Eventually it goes dark.

The speaker may or may not turn itself back on again. Ours did not. If, like ours, yours did not, then go ahead with the next step (Step 10). But if yours did, then skip Step 10, and pick up with Step 11.





10. Power On the JBL Charge 3

Press the dark   Power  button to turn the speaker on. It should again pair with your mobile device where you’re running the JBL Connect app. The  Power button turns solid blue when your speaker has successfully paired again with your tablet or phone.

11. Back in the App, Press the Done Button

Then with your speaker successfully paired to the JBL Connect app again, press the green  Done  button.

The app then displays the JBL Charge 3 status screen once again. But this time, note that there’s no longer the orange circled explanation point (!). This means that the firmware update succeeded. So now, the speaker is running the current version.
