Hi @micaelasalde, welcome to the Sonos Community!
I’m sorry to hear that you’re having trouble updating your Era 100.
You’ve done all the steps I would suggest, however if you haven’t tried using the Desktop Controller to update (either Windows or Mac), try that first. If that doesn’t help though, then I’d recommend submitting a diagnostics after the update error shows then reach out to our support team. They have the tools available to look into your system to see what’s going wrong and help you resolve it.
I hope this helps!
Did this work? I'm having the same problem on Sonos Five Gen 2 and a Play:3
I have the same problem. Just bought two Era 100, but when I try to connect them to the system I keep getting “Error code 1108 - We couldnt update your Era 100”. This is driving me insane and I am very close to throwing these bloody speakers in the bin. I have updated my system using the web app and its now fully updated (No updates required). What do I do????. Also, as soon as I plug them in the web app stops working…. This is totally rubbish. If I had not spent so much money on other Sonos products I would gone for another, more reliable product, but it seems I am stuck with this inferior system, and I need it to work
Have you tried with the mobile controller, rather than the web app? If so, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, they get sensitive about GDPR.
There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.
When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.
Thanks. I have contacted Sonos Support, provided diagnostic results/number, reset the speakers (3 times) etc, but, they were unable to help me. Bought the speakers on Amazon. Just spoke to them and I will be returning the speakers tomorrow. Very, very disappointed!
