Charge 3 Firmware Update, How To, Tips, Help

Here, we demonstrate the Charge 3 Firmware Update on the JBL Charge 3 Bluetooth speaker. This upgrade can take up to thirty minutes depending on the speed of your internet connection. Plus, it cannot easily be undone. You won’t be able to return to the previous firmware version once you complete this software upgrade. So, be sure that you indeed wish the upgrade and have considered all of its ramifications before proceeding.





Prepare for Charge 3 Firmware Update

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 Charge 3 speaker itself.

So, get your mobile device connected to the internet and install the Connect+ app if you haven’t already.

Connect your 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 corrupted version of the firmware in the speaker’s memory, and brick the speaker, rendering it useless and not repairable.

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

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

Charge 3 Firmware Update, How To

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+ (JBL Connect Plus) App

The app takes a few seconds to show you some pretty animations when you first start it. But then it locates your paired Charge 3 Bluetooth 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.

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

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

This screen gives details about the available firmware update. In our case here, it tells us that we need this upgrade to enable JBL Connect+ functionality on our Charge 3 speaker. Specifically, this software upgrade enhances the speaker operation by allowing it to connect into a group of up to a hundred JBL Connect+ compatible wireless speakers, such that they all stream the same content, in synchronization with each other. You would do this when you wish to blanket a large area with music for dancing for example.





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

This page warns us that this particular speaker firmware cannot be undone, and that once done, this software upgrade is permanent in the speaker. It also says that after this upgrade, the speaker we’re updating will no longer be able to connect with other Charge 3 Bluetooth speakers that are running older versions of the firmware. You will also lose connectivity with older speakers such as the 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 Charge 3 firmware upgrade confirmation prompt screen, as shown next.

This prompt again warns us that we won’t be able to fall back to the old firmware version once this upgrade is complete. It then asks us to decide whether to install the new firmware or to cancel out. We’re going ahead, in the next step.

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

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

This page tells us to connect our Charge 3 speaker to AC power if we’ve not done so already (You would have already done this if you were following the instructions in the preliminaries section above).

7. Connect the Charge 3 to AC Power if Not Done Already

We connected our Charge 3 to an AC outlet via the included power adapter and cable, as shown in the next picture.

8. Tap the OK Button

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.

The firmware update then begins, with the download of the firmware update file from the internet, through your mobile device, to the speaker via the Bluetooth connection, as shown in the next screenshots.

8a. Charge 3 Firmware Update 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.

8d. Firmware Upgrade File Transfer 100 Percent Complete

Once the app copies the upgrade file to the Charge 3 speaker, you get the Upgrade Successful screen, as shown next. However, note that the Charge 3 is still upgrading to the new firmware for nearly a minute after you first see this green and white screen. Thus, this screen warns us that our speaker will restart automatically, and it asks us not to unplug the Charge 3 while it’s running the update process.

The speaker may or may not turn itself back on again. Ours did not. If, like ours, yours did not come back up after the firmware upgrade, 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 Charge 3

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

11. Press the Done Button

With your Charge 3 successfully paired to the JBL Connect+ app again, press the green Done button, as shown in the last screenshot.

The app then displays the Charge 3 status screen once again. However, this time, note that there’s no longer the orange circled explanation point (!), as shown next. This indicates that the firmware update succeeded and that the speaker is now running the current firmware version.
