Having trouble with issues while trying to download and install updates for your Sonos system? Follow this step-by-step guide with details on how to fix error codes 888, 1009, 1010 and 1011 when updating Sonos speaker!
How to Troubleshoot & Fix Error 1011, 1009, 888 or 1010 when Updating your Sonos Firmware or Device Software
One of these errors occur due to low battery power, usually below the 20% level, during the fimware update installation. Another cause could be an issue with your WiFi Internet network connection which is very common. Lastly, Sonos device software updates fail because the update was cancelled manually on the Sonos app.

Whatever the case may be, you can find the troubleshooting methods and solutions below to be helpful in finding an effective fix for error code 1011, 1009, 1010 or 888 when updating Sonos smart speakers.
Reset your Sonos
Most of the time, a Sonos system with error code 888, 1009, 1010, or 1011 can be fixed by just resetting the device. Press and hold the Mute and Volume Up buttons on your device for 10 seconds, or until you hear a voice alert. This will reset the system. Try testing your device again to see if the error code is still there after it has fully restarted and updated itself with the latest software.
Logout from your Account
Another thing you could do to fix these problems is log out of your account and then log back in.
- To do this, open the app and go to Settings, Advanced Settings, and My Sonos Account.
- Choose “Sign Out” from the title bar at the top of the screen, and then sign back in with your email address or username for that account.
- Try running a test update again to see if it works correctly.
Use Ethernet Cables to Update (When Possible)
If you’re using wireless connections from one or more devices to connect to Sonos products, you might want to try updating them all through an Ethernet cable connection instead, only if it is possible.
This could help fix latency problems that are making updating hard. Before trying another update test with Sonos products on these networks, plug both ends of an Ethernet cable into their correct ports on your router and device.
Keep Wireless Networks Separate if Sonos Products are Using Them

Wireless connections can experience interference, which can lead to bad results when trying to update multiple products in a single home network environment.
You should try to isolate all Internet activity that has nothing to do with what you’re doing with your Sonos products. This means turning off any other devices, like computers or tablets, that are using the same Wi-Fi signal at the same time.
Any unnecessary devices should also be turned off or removed from the settings so that your attempts to update aren’t hampered by other traffic overloading local networks, routers, etc.
Move The Ailerons Away From Other Equipment Or Sources Of Interference
In addition to isolating Wi-Fi sources used by multiple devices in a given home space, we also recommend moving any wireless transmitters (such as aerial antennas) away from where they may interfere with each other, if possible.
This is especially important if they are mounted close together or use similar wavelengths that give priority to certain kinds of signals over others during different stages of downloading updates, etc.
The workaround will help reduce instability caused by changes in signal strength caused by radiated energy fields that temporarily block communication between connected parts whenever information needs to be sent back and forth (like during downloads).
Make Sure the Firmware Version Matches the Software Version your System is Using

It’s very important for users who try to do complex installations without help from Universal technical support staff to double check any updates they do manually against their official documentation online before rolling out changes on their own.
This could save them time and money in the long run.
Check the Network Infrastructure for Relevant Firewall Settings or Permission Groups
If members of a company’s departments have recently changed any settings related to internet access or traffic control, it’s possible that firewalls running on specific networks that have been segmented off for security reasons are blocking access to certain areas because of privileges assigned to individual users.
Checking that users have the right authority levels will let Sonos products like smart speakers connect to the internet successfully.
It would stop the needless chaos that happens when unintentional changes are made without the owner’s knowledge and cause IT workers who are in charge of managing systems to be confused.
