Hi @Jump_of_Stupid,
I’m sorry to hear that you’re having trouble with your Sonos Roam.
I’ve had a look into the case linked on your account and the agent you spoke with has performed all the steps I’d suggest doing. You could try to hold the power button for 15 seconds with the Roam disconnected from any charging cable, but if the LED goes back to and stays flashing white after you let go of the power button after 15 seconds, then any other steps I could suggest would be something you’ve done already.
For out of warranty products, the discount you’d get can be used towards any Sonos product. You could use return the Roam and then keep the discount to use on a different product if a replacement Roam doesn’t suit your needs. You’ll likely need to get new return information generated from looking at the date on the case, but all you need to do is: contact our support team, give them the email address linked to your system, and request new return labels.
I hope this information helps!
