I just purchased three ROAM SLs that were listed as “new” on a big box electronic store website but sold through a third party “marketplace seller”.
While attempting setup on one unit I kept encountering numerous errors (Errors 36 and 1032/1002 on mobile, 888 on the windows desktop app...), all of which suggested a hangup in software/firmware updates. Ok, no sweat I thought - we’ll just perform a reset per community instructions. However, when the time came to unplug the unit to perform the reset, the Sonos just blacked out. I thought maybe the battery fully depleted so I plugged it in to adequate charger per Sonos instructions - 1 hour, 2 hours, overnight. No matter what, the unit would only turn on if plugged in - and even then, no sound from the unit itself.
That had me thinking perhaps I had 1 bad unit - but this exact issue presented on each of the 3 Roams I purchased. To be clear: (1) no evidence of shipping damage; (2) no evidence of used or “open box” status - everything looked “factory clean”; (3) the units themselves look brand new; (4) when plugged in, the unit detects and wants to connect to my network, but can’t because the firm/software update shuts the process down.
I tried just about every fix sequence suggested by Sonos, forums, community (even chatGPT). Soft reset, hard reset, factory reset; uninstall-reinstalling all apps; removing entire system (including other Sonos devices) from network, attempting to build from scratch; purged cache, purged data...about to purge my brain at this point.
It is my understanding that a unit that has been sitting on a shelf too long maybe so battery depleted or so out of date soft/firmware wise that it can interfere with battery charging - but for a seller to sell THREE units that all express this failure mode with no apparent fix seems suspicious.
Am I missing something?
