Here, we detail the Sony SRS XG300 software update procedure. This routine can take ten (10) to fifteen (15) minutes depending on the speed of your internet connection, source device used to update the 300, distance between speaker and that device, Etc. Plus, you cannot revert the update once you install it. That is, you’ll be unable to return to the earlier software version after you finish this upgrade. So, be sure that you indeed want the update, and have thought through all ramifications before continuing.
You’ll need the following items:
Next, do the following to update the speaker. In short…
We plugged ours to an AC outlet using the power supply that comes with the unit. E.g. See this in the next picture.
You’ll know that the 300 is receiving external power if you see the charging light glowing orange.
Next, connect the 300 to your phone / tablet where you will run the update. Here’s an example screenshot of the XG300 linked to an iPad.
Now keep both the 300 and your mobile device powered up and close to each other throughout the process, lest the update fail and result in a malfunctioning speaker.
We made a folder for all of Bluetooth apps and put the Sony Music Center app in there on our test iPad, as you see in the next picture.
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 XG 300 . But eventually, it does so, and displays its status screen, as we show next.
If the 300 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 XG300’s home screen. This appears only when a firmware update is available for this particular unit.
Note that if there are no software updates pending for the 300, then you will see no brown bar. This situation we show in the next picture.
Tapping the More Info button brings up the Software Information screen, as follows.
Tapping the OK button may bring up the following screen if you haven’t followed the above directions, and did not plug the 300 into external power.
In fact, we suggest that you fully charge both the 300 and the smart device before proceeding with this update. Doing so protects the 300 from a corrupt software upload in the event of a longer power outage, where the batteries could go dead before updating is done. Also, as a further precaution, once you fully recharge both devices, please leave both of them connected to external power until the update finishes.
Once the unit and smart device finish charging, 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.
The updating then starts, as we show in the following screenshots. The Music Center app first downloads the new firmware package.
Once the app downloads the package, it unpacks and transfers it to the XG300 as the next pictures show.
Additionally, during the transfer to the 300, the Power lamp on it pulses 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 unit are OFF.
Now as we see in these screenshots, the Sony Music Center app displays a progress line, that gradually gets more brown as the software updating proceeds.
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.
The next screen shows that the software transfer and update to the 300 are almost complete (99 percent complete). So the progress bar is practically all brown now.
Now that the new program has been transferred from your device to the speaker, the software update process on the XG300 begins when you see this page.
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 XG300 update process.
While the 300 updates, its Power lamp slowly pulses green.
Then after a minute or two, once the 300 finishes updating, the Power light goes dark. No more blinking.
Press the Power button to turn the unit on again, as pictured next.
The XG300 should again pair with your mobile device where you’re running the Sony Music Center app. The Power lamp glows solid green, and the Pairing lamp also glows steady blue once the 300 again links to your mobile device.
Now after the XG300 reconnects to your smart device, the Sony Music Center app discovers that your speaker has come back online, and thus, displays a software-update-complete message, as follows.
With your speaker successfully paired to the app again, press the OK button, as shown in the last screenshot.
The app then displays the XG 300 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 300 is now running the latest version.
Updating the Sony SRS XG300 is now complete.
