Tenho 2 dispositivos. Um voltou, outro não. O que voltou não cheguei a fazer o reset. Esse que não voltou não voltava se jeito nenhum, daí tive que tentar o reset. Continua sem conexão à rede Google. 

[Loppy]

I've managed to get my chromecast linked back to my TV

I've checked the firmware as per this thread and it is the same

So how do I actually start using it to cast again?

[si1127]

Thanks, it works now.

Hola a todos.

Yo restablecí el dispositivo a valores de fábrica  el domingo 8. El jueves 13 hice lo de configurar el chromecast cambiando la fecha del móvil a un día anterior al 8 de marzo y se pudo conectar a WiFi, pero seguía sin funcionar. El viernes por la tarde lo reinicié desenchufandolo y al rato ya podía enviar contenido como siempre.

# Chromecast Bug Solution: How I Fixed the Update Issue

## Problem Context
Following the recent bug affecting Chromecast devices, I encountered difficulties with my device that was no longer working properly. After several unsuccessful attempts with the usual solutions, I discovered an alternative method that worked perfectly.

## Step-by-Step Solution

1. **Factory Reset the Chromecast**
- I first performed a complete factory reset of my Chromecast to start with a clean slate.

2. **Change the Date on my Smartphone**
- Instead of attempting a standard configuration, I modified the date on my phone to set it to an earlier date.

3. **Configure the Chromecast with the Modified Date**
- I then proceeded to configure my Chromecast while my phone was set to this past date.
- This allowed the Chromecast to start the update process without encountering the current bug.

4. **Successful Update**
- The Chromecast was able to download and install the update correctly.
- The device restarted after the update.

5. **Return to the Current Date**
- Once the update was complete, I set my phone and the Chromecast back to the current date.
- The device is now perfectly functional.

## Why Does This Method Work?
It appears that the current bug is related to a date verification or certificate issue in the latest version. By setting the device to an earlier date, we allow the device to access a firmware version that is not affected by this problem.

## Conclusion
This simple but effective solution allowed me to regain the use of my Chromecast without waiting for an official fix from Google. I hope this trick can help other users facing the same problem.

Feel free to contact me if you have any questions about the procedure!

A lot of people including me have factory reset the device while troubleshooting. Waiting eagerly for an update on that.

If I try to add chromecast as new device now through google home it does find it over bluetooth but fails to connect.

[Lori27]

The connection is dodgy, keeps wavering in and out. So annoying 😑

いつ頃になりますか？

工場出荷に戻してしまったので、早く解決することを心待ちにしています。

Bonjour, 

Si cela peut vous être utile, j'avais effectué une réinitialisation d'usine et malgré le débranchement du chromecast de la prise secteur pendant quelques minutes pour redémarrage, cela ne fonctionne pas.

Il semble qu'il ne reçoive pas la mise à jour... 

Certains membres préconisent le changement d'une date pour que cela fonctionne à nouveau, mais je n'ose pas le faire de peur que cela affecte la suite puisque vous êtes dessus... 

Pensez-vous que cela puisse être le cas ou puis-je tenter cette méthode ?

Merci pour votre réponse et bon courage ! 

[Nozza]

Any news for those that factory reset?

[Gerbhead]

When chromecast stops workin factory reset is a top option to get goin again. By the the time google sent an email that issue was on their end i had factory reset my chromecasts multiple times. Let’s go Google, fix it or send me new chromecasts

[gerzellmann]

It works again, thanks. 

[shellengo]

I am still not able to setup my device, as I have made a reset 😞

Please help

[Antosss]

For those who performed a factory reset, simply manually set your smartphone date before march 9th and pair your Chromecast again, it will connect correctly and download the latest firmware.

[Prave]

I still have a problem to authentication  between GoogleHome and Chromecast device in registering operation. I had already reset my device , before your communication.

[Wepsty]

Il Chromecast non riesce a connettersi con il wifi e avevo fatto purtroppo l' aggiornamento

[Camille68]

Tjs pas de solution pour ceux  qui ont tenté la reconfig d'usine ????

[L71]

Setting the date back on smartphones seems to solve the factory reset issue. It has helped alot of people here in the chat.

[Anouk1]

I did factory reset when trouble first started. Android and iPhones still can’t communicate with chromecast.

[Joel_for]

For those who did perform factory reset, change the date of your phone at before March 6th (for example March 1st) and redo the setup of the chromecast. 
It should works 

[No0op]

Have performed factory reset and error is "couldn't not communicate with Chromecast" Awaiting for resolution. 

[Debora12]

Isso é muito bonito, mas como devem saber, a primeira coisa que muita gente fez, quando percebeu que isto não funcionava, foi refazer os padrões de fábrica.. 

Para quando essa solução?? 

[Jgamble32]

So I went a step further after factory resetting and removed the device from my Google home in hopes of reinstalling it and it working. Now I don’t have the option to update my firmware. Any suggestions on how I can proceed from here?

[OBusch]

I did the reset (of course). But today I could easily re-install my CCA, fist time failed, second time succesfully. Done.

[Johnsvv1180]

When trying to access Chromecast,I'm getting the message "Couldn't communicate with your Chromecast"

[JorgeAmaral]

I performed a factory reset. What do I do now?

[Bobo4]

Go to settings on your phone,  change the date to March 5th, perform setup again once completed switch you're phone back to correct date.. this should fix it

[Marietta1989]

Ça ne fonctionne toujours pas

[Anonymous]

Unfortunately, I did a factory reset due to the desperation of so many days without the system. I hope there is a solution.

[David73]

I am one of the customers that performed a factory reset. Unfortunately, at that same time,  I also removed my device tile for Google Home. I  tried to add it again without success. So I cannot access my Chromecast firmware version to see what it is. Anyway, I have not received any fixes for someone who did a factory reset. Can you help? 

[Starplus7]

Still not working due to reboot. Cant wait for it proper fix 

[Barbot]

Bonjour 

Je n'arrive toujours pas a le connecter !!!

[Bravo1]

I did a factory reset, so I continue having issues, waiting for your help please.

[Jgamble32]

For iPhone users you can turn all your location services off which will allow you to change your date and time. I was able to update my firmware by doing that and changing the date like suggested by many users

[Tommykearney2]

When will a fix be released for people who did a factory reset?
