Sometimes when trying to update a MusicFlow product, the update fails.
You can update the Music Flow system in different ways:
The app will be updated automatically by the appstore or market.
The speakers are update by using the app.
Open the menu and go to settings>version info
Wait until the app has scanned your network for all speakers.
Behind every speaker you can see if the speaker firmware needs updating.
If any speaker needs updating you can press the two-arrow icon next to "device version info"
When this update fails the best way to solve this is to keep trying.
The main cause is a bad network connection. The speaker will continue downloading and after a couple of tries
the update should be downloaded and the speaker will install it. If it does not work, just keep trying.
If the update really does not work, try to turn off all the speakers but one. open the app and go to the update page.
Run the update, keep trying until the update is downloaded, and repeat this for every speaker.
This method can be tedious, but I will work, even though you might need to try several times.
keep trying if at first it seems it does not work.
