Chromecast defined in Home as previously registered by different user even after factory reset

[Heffatussi]

My internet was out during the day, and when i got home  none of my streaming apps are able to connect to my chromecast. I tried on Home, but nothing.  What has worked for me before is to remove the device an re-install it in Home, but not this time. I have done an insane amount of factory reset attemtps in the last hour. But no matter what i do Home keeps saying the device has preciously been set up by a different user. I have tried restarting the router twice, unplugged everything. Any advice?

Hi @Heffatussi,

Thank you for reaching out to the community! I'm sorry to hear you're having setup issues with your Chromecast, as the Google Home app provides the message that the device is already set up under another account. I appreciate you taking the time to troubleshoot this! Let me take it from here.

To get a better handle on what's happening with your Chromecast, could you tell me a bit more about it:

• Which Chromecast model are you using? If you're not sure, no worries! You can find all the details in our 'Chromecast and Google TV Streamer specifications' Help Center.
• Is your Google Home app up to date?
• Do you have a dual-band router?
• Is your Chromecast currently connected to the 5 GHz network?

While you're gathering that info, you could also try these steps to remove your Chromecast:

• Directly through your Google Account:
  • Head over to Device Activity and log in to your Google account.
  • Spot your Chromecast in the list of devices.
  • Click on it, and then choose either Sign out or Remove.
• Using the Google Home App (if you can access it):
• Open up the Google Home app.
• Tap and hold the Chromecast's tile.
• Tap the Settings icon (it usually looks like a gear).
• Look for an option like Remove device or Unlink account. If you see it, tap it and confirm.

Once you have this information, I will be more than ready to assist you with this.

Best regards,

Debora
