Google fixed Chromecast: how to update it and what to do if you factory reset it

Second-generation Chromecast and Chromecast Audio users were unable to use their devices after receiving a message indicating "untrusted device". This prevented them from executing any function.

The problem was caused by the expiration of an authentication certificate, which blocked the connection to Google's servers. After several complaints, the company released a firmware update that fixes the issue.

Google released an update to fix the problem

Google recommended not performing a factory reset, as this could cause more complications. Instead, it confirmed that the solution comes through an automatic firmware update.

Users who haven't reset their device should receive the update without needing to make any manual adjustments. This will allow their Chromecast to function normally again.

What if you already factory reset your Chromecast?

Many users tried to solve the problem with a factory reset, but this measure left the devices unusable. By doing so, the Chromecast can't complete the initial setup, preventing its use.

Google reported that it will soon provide specific instructions for affected users to set up their devices again. Meanwhile, it advised waiting for the official update before attempting a new installation.

How to know if your Chromecast has already received the update?

• If you haven't factory reset it, try connecting it and check if it already works.
• If it still doesn't respond, restart it and check if it receives the update.
• If you have factory reset it, wait for Google's instructions before reconfiguring it.

The solution is already underway, and it is expected that all devices will be functioning without issues in the coming days.
