Here, we demo how updating firmware on JBL Xtreme speaker works for this awesome sounding wireless speaker. This updating might take up to a half hour, depending on the speed of your internet. Plus, you cannot reverse it without a lot of effort. That is, you won’t be able to downgrade to the prior firmware version once you upgrade to the latest firmware version. So, know for sure that you really wish the update, thinking about all its gotchas before updating.
We were unable to update our JBL Xtreme firmware when we received this speaker at the time of this writing. Why? Because the firmware there was already at 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 Xtreme speaker where we could however. The firmware updating processes are alike for both speakers. Finally, if we see an actual firmware update notification for our Xtreme, we’ll update these photos to show the update in progress on that speaker.
Prepare for Updating Firmware on JBL Xtreme
Connect to the Internet
You must have internet connection, a Bluetooth enabled mobile or desktop computer device, and the JBL Connect Plus (Connect+) app, as well as the JBL Xtreme speaker when updating the speaker firmware.
Install the Connect+ App
So, log your mobile device onto the internet. Then install the Connect+ app if you haven’t yet done so.
Plug your JBL Xtreme into AC Power
Connect your Xstreme to AC power. Why? Because we don’t want its battery going dead while updating the firmware. This could result in corrupted software in the speaker’s memory, and thus, break it forever.
Connect your Xtreme with your Mobile Device
Then, pair your phone or tablet with the Xtreme JBL speaker.
You are now ready to begin the firmware updating process on that speaker.
Updating Firmware on JBL Xtreme Speaker, How To
1. Find the JBL Connect+ App on your Mobile Device
We found ours on the fourth home page in our iPad Air, as seen next.
2. Run the JBL Connect+ (JBL Connect Plus) App
The app displays some animations when you first start it. But then it finds your paired JBL Xtreme speaker and shows you its status screen, as shown next.
Note the bang point inside the orange circle in the top right corner of the speaker’s picture, as pointed at by the dark green arrow. This shows that there are important messages about this speaker for you to read and act upon.
Note that if there are no current messages or firmware updates available for this 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. Tap the Orange Circled Bang Point (!)
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 this case, it tells us to upgrade to enable JBL Connect+ functionality. Detail: This software upgrade improves speaker operation by letting it join a group of up to a hundred JBL Connect+ wireless speakers. Then, they all play the same content. E.g. You would do this when you want to fill a large area with music for dancing.
4. Flick to the Left to See the Next IMPORTANT NOTICE Page to Continue with Updating Firmware on JBL Xtreme
This page warns us that we cannot undo the speaker firmware updating, and that once done, this upgrade is permanent. It also says that after this upgrade, the speaker will no longer connect with other Xtreme 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 JBL Xtreme updating firmware 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 updating finishes. It then asks us to decide whether to install the new firmware, or to cancel the operation. We’re going ahead, in the next step.
6. Tap the INSTALL Button
Touching the INSTALL button brings up the Upgrade Speaker screen as shown next.
This page tells us to connect our Xtreme speaker to AC power if we’ve not done so already (You would have already done this if you followed the instructions in the first section above).
7. Connect the JBL Xtreme to AC Power if Not Done Already to Continue with Updating Firmware on JBL Xtreme
We plugged our Xtreme into an AC outlet in the prep for firmware updating steps above, using the included power adapter and cable, as shown in the next picture.
8. Tap the OK Button on the Upgrade Speaker Screen
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.
The firmware updating on the JBL Xtreme then starts. It begins by downloading the software update file from the internet. This file moves through your mobile device, to the speaker via the Bluetooth connection, as shown in the next screenshots.
8a. The JBL Xtreme Updating Firmware Process Starts
Copying the file from the internet to the speaker is the slowest part of the firmware updating process. But as shown in these screenshots, the JBL Connect+ app displays a progress pie-chart, that fills in with more orange as the firmware file transfer proceeds.
8b. JBL Xtreme Updating Firmware at Forty Percent Complete
This was probably around fourteen minutes into the firmware updating at this point in the process.
8c. JBL Xtreme Firmware Updating at 65.7 Percent Done
The next screenshot shows the upgrade file transfer at 65.7 percent complete.
8d. Firmware Upgrade File Transfer 100 Percent Complete
The next screen shows that the firmware file transfer to the speaker has finished (100 percent done). The pie chart is fully orange now.
8e. The Upgrade Successful Screen Appears
Once the app copies the upgrade file to the Xtreme speaker, you get the Upgrade Successful screen, as shown next.
But note that the JBL Xtreme is still upgrading to the new firmware for nearly a minute after you first see this green and white screen. Thus, this screen warns that our speaker will restart by itself after it installs the new firmware. So it asks us not to unplug the Xtreme while it’s running the update process.
9. Wait for the JBL Xtreme to Shut Off to Continue with Updating Firmware on JBL Xtreme
Watch the power light on the speaker, as shown next.
Eventually the lamp goes dark, as shown next, pointed at by the green arrow.
The Xtreme may or may not turn itself back on again after the updating. Ours did not though. 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
Press the dark Power button to turn the Xtrene 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 Xtreme successfully paired to the JBL Connect+ app again, press the green Done button in the Connect+ app, as shown in the last screenshot above.
The app then shows the JBL Xtreme speaker status screen again. But this time, we no longer see the orange circled bang point (!), as shown next. This means that updating the firmware worked, and thus, the speaker is now running the current firmware version.
12. Done with Updating Firmware on the JBL Xtreme !
You have now updated the firmware to the current version in your JBL Xtreme Bluetooth speaker. Enjoy all the new features.
