Hola Google si hicieron el factor y reset para volver a configurarlo sólo deben poner fecha de 8 de marzo en sus móviles y volver a levantarlo. Luego solo queda esperar la actualización 

[Elrick26]

Para los que lo resetearon.

Vayan a sus ajustes de su telefono/tablet y pongan la fecha antes del 9 de marzo. Depues, abran la aplicación de Home y vuelvan a configurar su Chromecast, una vez que teeminen de volver a instalar y configurar, regresan I afecha normal a su dispositivo y tratan de trasmitir algo a su Chromecast, les va a salir un mensaje de que el firware no wsta actualizado. Con esto quedara otra vez configura y enlazado su chrome como si no lo hubiesen reseteado. Esto es oara volverlo a configurar.

Y de ahi esperar a que Google solucione el problema

For those who reset their device:

Go to your phone or tablet settings and set the date to before March 9. Then, open the Google Home app and set up your Chromecast again.

Once you’ve finished reinstalling and configuring it, change your device’s date back to the current date. When you try to cast something to your Chromecast, you’ll see a message saying that the firmware is not up to date.

This process will restore your Chromecast as if it had never been reset. This is just a workaround to get it set up again while we wait for Google to fix the issue.

[Sejer]

When I set the correct date afterwards and try to cast - I am not getting the msessage you mention. Neither do I get it if I try to set the date back to prior to 9th march. In either case, I get a message indicating that the connection failed.

@Elrick26

sauf que moi l’appareil essaie bien de se connecter au Chromecast pendant un moment puis échoue mais il n’y a ensuite aucun message

[Pennyfenfen]

Please fix it. And also its ridiculous to say no factory reset because that's what the troubleshoot says to do. Please I don't want to buy another thing it worked so well for so many years. 😫 Please try 🙏 

[LaconchadetuH]

Take your time mutterfukeer we are allready 5 days of service down. If it takes too long and I end up buying some other device, beleive me it wont be from google and I will never ever spend a cent in you ash*les.

[Richard-J]

Time for an update Google.  Either that or you replace devices you have rendered inoperable at your expense. 

[Visito1]

Awesome, i already factory reset. What a joke. 

[Hyde]

Biensur j'ai reset mon chromecast.

Merci pour l'info 

[Tmoh5vV6dxyoSEu]

Still not working, causing severe business disruption.

[LaconchadetuH]

ABSOLUTELLY EVERYBODY DID A FACTORY RESET, you retarsd put the reset buttom in the device to solve this kind of problems - Move your fucingk assss quicker, or loose a lot of customers.

[DrWig]

My trusty Chromecast Audio has been rock solid for years, so I'm very glad it hasn't bricked, and it's just a bug.  Very much looking forward to it coming back online!

[Williams86]

I wait for the solution.

Thank you 

[AD57]

Grazie, per favore inviatemi le istruzioni per configurare il dispositivo Chromecast al seguente indirizzo email #

[Anonymous]

Ho prutroppo effettuato il reset ma sono poi riuscito a ricollegare il Chromecast alla rete in questa maniera: ho disattivato data e ora automatico su smartphone ed ho impostato una data antecedente al giorno del bug. Dopodiché riprovando a configurare sono riuscito a comunicare con il Chromecast e a ricollegarlo al wifi. Ora attendo paziente l'aggiornamento. Provate!

[AlfieTheCat]

How long do I have to leave it turned on? I get rolling wallpaper pictures but no connection to my phone to stream.

[pattysp23]

Hello everyone, how are you?

Great. Unfortunately, I reinstalled the factory settings, so it still hasn't started working again. I'll follow up here to see if we can find a solution.

Thanks team

JUST CHANGE THE DATE ON YOUR PHONE TO SET UP YOUR CHROMECAST 2nd GEN AFTER A FACTORY RESET!

Hey everybody,

I performed a factory reset on my Chromecast 2nd gen and I found a way how to set it up back again - just change the date on your phone to anything before March 9, 2025 (when the certificate in our Chromecasts 2nd Gen expired) and using Google Home app just set it up as you normally would. It works!

But it didn't fix the issue of streaming. I will wait for the official fix from Google to install. At the moment, at least here in Slovakia, it has not been rolled out.

But if you can't wait, then read here. They found a way:

[Cristinagarri]

Yo restablecí el mio de fabrica,  espero la ayuda urgente.  Gracias 

[joelios]

Si lo restableciste como yo, solo cambia la fecha de tu teléfono al 8 de marzo o fecha anterior e inicia el proceso de configurar tu Chromecast desde la app de Google Home. Lastimosamente ésto aún no soluciona el problema de enviar contenido, pero sí te deja en la pantalla de fondos pantalla de Chromecast para que pueda recibir la actualización

[meriane]

Como será avisado que o problema está solucionado 

[Sammie1sam]

So what do I do if I’ve already reset it, As all info online suggests? What now? 

[Sitraek]

La actualización nunca llego a mi dispositivo claramente conectado a la red. No logro comprender como google llego a ser tan ineficiente

[Dante515]

No RUSH bro... just 5 days into THE MESS YOU FOLKS CREATED!!!

[Chandii]

Hi Team, 

Will you be posting the updates on the fixes on those that have performed a factory reset or cannot re setup our devices on this page? That would be helpful. Cheers

[Anonymous]

Hola si lo reinicie de fábrica que hago ahora gracias 

[Missgem]

Its been over four days since you recognized the issue. Why do I feel like you just bricked all our devices so we'd have to upgrade? 

[Juanma64]

Al día de hoy 12/3 mis cromecast 2 sigue sin andar solo me muestra imágenes fotográficas de google

[Jadorewulf]

And when will can find out ? Can you guys email us ?

[Daiacurtis]

La gran mayoría de los usuarios restablecimos de fábrica. Hay gente que utiliza el Chromecasr g2 todo el tiempo todo los días. Si tan solo hubieran enviado un comunicado previo no estaríamos en estos aprietos. Si esto no tiene solución van a perder miles de clientes, que seguridad me da que si compro otro de los más actuales el año que viene ya no funcione. Saludos

[Juanlu78]

Hi,

I cannot configure mu device so how can it be connected?

I reseted it the first time and I cannot connect now. What should I do?

[LuisAr91]

I have chromecast 3 and still have the errro! 

[IW]

So days after the issue came to light, you tell people not to factory reset? Guess what? That horse has long bolted! Your Help page told users TO DO A FACTORY RESET! Shessshhhhh

[FuksiarZ]

We are waiting impatiently, little daughter Olivia, no bedtime stories, well, we keep our fingers crossed that you will solve the problem 👍 soon

[Silvia1]

Como faz a restauração de fabrica? Eu resetei o Chromecast, isso que restaurar?

[unkeith]

If a user has conducted a factort reset, why not just roll back date on moblie device to pre certificate expiration date. Shouldn't this allow Chromecast device connectivity to recieve fix (updated certificate) ?

[PeanuttyRandy]

Awww man. I factory reset my chromecast before seeing this post. 

[Orel2]

Bonjour 

Cela fait 3 jours que sa ne fonctionne pas , impossible de me connecter à Netflix je paye mon abonnement pour rien 😡

[Taissa]

Mas quanto tempo isso vai levar ? Eu preciso do aparelho para trabalhar 😢 não consigo conectar. Fica um silêncio aqui no meu salão. Da pra imaginar um salão sen televisão e sem música?

[Jsoca]

Cuanto hay que esperar para que se actualice mi dispositivo?
