Google finally rolls out fix for ‘Untrusted Device’ errors on older Chromecasts

What you need to know

• The “Untrusted device” error early this month primarily affected older Chromecast and Chromecast Audio users and caused a significant inconvenience.

• For users who’d factory reset their devices, the search giant advises updating the Google Home app and setting up the affected devices again to resolve the issue.

Early this month, several older Chromecast owners reported issues with their devices as they were seeing “Untrusted device” errors. The issue was particularly faced by 2nd-generation Chromecast and Chromecast Audio users. While the search giant has already addressed the issue, it is now finally rolling out a fix.

Earlier this week, the Google Nest Team, in a corresponding support page, apologized for the inconvenience and disruption caused and further notes that they are “committed to ensuring all users are back up and running as quickly as possible.”

For users who’ve faced the issue and their devices still don’t function as intended, the Google Nest team advises them to check the firmware version of the device — firmware version 1.56.467165 for 2nd gen Chromecast and firmware version 1.56.467166 for the Chromecast Audio — and follow with an accompanying instruction page.

Further, if their device doesn’t match the corresponding firmware version, users need to reboot their devices and start the update process, which seemingly should make the broken devices function normally.

When Google addressed the issue last week, it recommended users not factory reset their Chromecast devices. However, for those who have already done that, here’s what you need to do.
