Here, we detail the software update procedure for the Sony XB33 cordless speaker. This routine can take ten (10) to fifteen (15) minutes depending on the speed of your internet connection, source device used to update the speaker, distance between speaker and that device, Etc. Plus, you cannot roll back the update once installed. That is, you’ll be unable to return to the prior software after you finish this upgrade. So, be sure that you indeed want the update, and have thought through all ramifications before proceeding.
Prepare for Sony XB33 Software Update
You’ll need the following items:
-
- High speed internet connection,
- Bluetooth enabled mobile device,
- The Sony Music Center app that runs on said mobile device,
- the Sony XB33 BT speaker you’re updating.
- Compatible power adapters and charge cables for your speaker and mobile device.
Summary for Sony XB33 Software Update Directions
Next, do the following to update the speaker. In short…
-
- Connect your source device to the internet. We suggest using WiFi for this operation, and not your cellular connection.
- Install the Sony Music Center app if you haven’t already.
- Then, plug both the XB33 and your mobile device to AC power. Why? Because we don’t want either of their batteries going dead while updating the firmware. In fact, a low battery could leave a corrupted version of the software in the speaker’s memory. This could, and probably would brick the speaker. This would then likely render the unit useless and non repairable. So once again, connect the speaker to power before proceeding. Please !
- Disconnect any other wireless speakers and devices from your source mobile device for this process.
- Then, power up your speaker and source device, if not already running.
- Next, pair your mobile device with the XB33.
- Run the Sony Music Center app. The app should then find your speaker and display the home screen for the 33, showing that a software update is available.
- Follow the on-screen instructions for updating.
Sony XB33 Software Update, Step by Step Details
1. Connect the XB33 and your Mobile Device to AC Power
We connected ours to an AC outlet using a common USB power supply, as well as a common micro USB to USB-A cable. E.g. See this in the next picture.
You’ll know that the speaker is receiving outside power if you see the charging light glowing orange.
2. Pair this BT Speaker with your Source Device
Connect the speaker to your phone / tablet where you will run the update. Here’s an example screenshot of the XB33 connected to an iPad.
Now keep both the speaker and your mobile device powered up and close to each other throughout the update, lest the update fail and result in a malfunctioning speaker.
3. Find the Sony Music Center App on your Source Device
We made a folder for all of Bluetooth speaker apps and put the Sony Music Center app in there on our test iPad, as you see in the next picture.
4. Run the Sony Music Center App to Continue with the Sony XB33 Software Update
As the app runs, it scans the host device running it for compatible Sony speakers. Wo, the app needs a brief period to find the XB 33. But eventually, it does, and then displays its status screen, as we show next.
If the speaker does not appear in the app after thirty seconds or so, move it closer to your mobile device. Next, close the Music Center app, and then run it again.
Note the tan bar on the XB33’s home screen. This appears only when a software update is available.
Note that if there are no software updates pending for the 33, then you will see no brown bar. This situation we show in the next picture.
5. Tap the More Info Button Inside the Brown Update Bar
Tapping the More Info button brings up the Software Information screen, as follows.
6. Tap the OK Button
Tapping the OK button may bring up the following screen if you haven’t followed the above directions, and failed to plug your speaker into AC power.
You might also get the following screen, even though you do indeed have the speaker connected to AC power.
This happens when the speaker has too little battery reserve power to complete the update should a power failure occur while you update. In fact, we suggest that you fully charge both speaker and the smart device before proceeding. Doing so protects your XB33 speaker from a corrupt software upload in the event of a prolonged power outage, where the batteries could die before software updating is over. Also, as a further safety measure, once you fully recharge both devices, please leave both of them connected to external power throughout the entire update process.
So, once both the speaker and smart device are charged, tap the OK button on the Connect Speaker to Power Supply window. That should then take you back to the previous page once again, as follows.
Or, if you quit the app, go ahead and restart it and repeat the above steps. This time, you should not get the Connect Speaker to Power Supply page. But instead, you will see the Software Information page that we see in the last picture.
7. The Sony XB33 Software Update Begins
The updating then starts, as we show in the following screenshots. The Music Center app first downloads the new software package.
Once the app downloads the package, it unpacks and transfers it to the XB33 as the next pictures show.
Additionally, during the transfer to the speaker, the Power lamp on the speaker’s top flashes green in groups of four pulses then a pause. E.g. Pulse-pulse-pulse-pulse-pause, pulse-pulse-pulse-pulse-pause,… During this time, all other lamps on the speaker are OFF.
7a. The Software Update Continues at Thirty Percent Complete
Now as we see in these screenshots, the Sony Music Center app displays a progress line, that gradually gets more brown as the updating proceeds.
7b. Now at Seventy Percent Complete
Now we’re probably about five minutes into the update. Indeed this process takes a relatively short time as compared to some of the other speaker models we’ve tested.
7c. Now at Ninety-Nine Percent Done
The next screen shows that the software transfer and update to the speaker have almost finished (99 percent done). E.g. The progress bar is practically all brown now.
7d. Software Update on the Sony XB33 Begins
Now that the software uploads from your device to the speaker, the update process on the 33 starts when you see this page.
7e Tap the OK Button
Touching the OK button takes you to the Speaker & Group page, where you see a list of previously connected speakers that the app knows about. Note that all are grayed out. So none are connected to the app during the XB33 update process.
8. Wait for the Sony XB33 to Shut OFF After Updating its Software
While the speaker updates itself, its Power lamp flashes green.
Then after a minute or two, once the 33 finishes updating, the Power light goes dark. No more blinking.
9. Press the Power Button To Boot the Speaker Again
Press the Power button to turn this 33 on again, as pictured next.
The XB33 should again pair with your mobile device where you’re running the Sony Music Center app. The Power light turns solid green, and the Pairing lamp also glows steadily blue once the speaker has again linked to your mobile device.
Now after the XB33 reconnects to your smart device, the Sony Music Center app discovers that your speaker has come back online, and thus, displays an update-complete message, as follows.
10. Press the OK Button Back in the Sony Music Center App
With your speaker successfully paired to the app again, press the OK button, as we show in the last screenshot.
The app then displays the Sony XB33 home screen once again. But this time, note that there’s no longer the brown bar, as we see next. This means that the updating of the software worked, and that the speaker is now running the current program version.
11. Done with Sony XB33 Software Update !
You’re now finished updating the software to the current version in your Sony XB33 BT speaker.
