Hello, I accidentally factory reset my Chromecast, what can I do now?

[JPablo]

Pleased I need the instructions to re-setup my chromecast! 

[zuchero]

Change date  on your mobile phone to 7-march-2025 and then you should be able to setup the device.

[Nusra]

Unfortunately i factory reset, because of alert that came up 

what to do now 

[Dee5]

Wow I have struggled with this for 4 days now 

Now I tried the help section 

And found out it's nothing to do with me ..

So what am I supposed to do now ? 

I can't watch anything on my TV anymore and I have paid for media subscriptions ? 

[Tanja1973]

Same here, i got the Problem 10 days now

[Anonymous]

surely this was not caused by an expired certificate or incomplete testing like people are saying? 😳

Please update us GoogleNestTeam - mine stopped working three days ago mid-stream and id like to use my product that I purchased through you. 

Oh and heaps of us would have factory reset seeing as that’s what your troubleshooting pages tell people to do for fixes. 

[Carolinenb]

Estamos aguardando urgente pois necessito do uso do aparelho para estudos

[frzjwz]

[cesar4]

Meu Chromecast não está configurando

[Pedro11]

Hi, any update on this issue? I didn’t receive any email related to my Chromecast v2.0. That still not working. Thanks!

[remil]

You should consider stopping giving your money to Trump, and investing it in those who actually support you: your customers 😋

[Miracleee]

I got email that the problem is fixed but am still can’t connect to the wifi network and i want to inform you that I already reset factory before I contact the customer support so I don’t know how to deal with my device now 

[tazz2]

due to illness I cant come out of bed.. just streaming tv.. now starring at the cealing! TY

[skellyplace]

It’s Thursday morning and this issue with Chromecasts not connecting or being recognized has been happening since Sunday, that’s 5 days of interrupted service. That’s 5 days of not being able to access streaming services we are paying for in the meantime. One of your traditional troubleshooting suggestions is to reboot the device. A day after the initial interruption you post a strong suggestion not to do that…likely a little too late for many who took this advice. This is an epic fail for Google. I really hope that a solution is still in the works. If the units that were reset have been bricked then compensation is in order regardless of the age of the units.

SSL certificate expired for a few million Chromecasts , there’re possible ways of fixing the issue which all involve code changes because I don’t see how they can fix it without code changes.  This will take time to fix if fixable at all .  I don’t believe we’ll have a fix quickly .

[edus17]

Fico no aguardo 

[Marpac58]

Vorrei cortesemente sapere quando pensate di risolvere il problema...sono passati diversi giorni ormai...è  sempre impossibile autenticare il dispositivo chromecast......grazie 

[Benrie]

First: I'm sorry about my "bad english", I'm tryeing my best to communicate with language that is not my usual speaking language.

At sunday I thought we had issues with wifi... And I tried to fix connection by multiple little things that I have had from advices earlier. After several hours of trying I did factory reset my device BECAUSE support.google.com/chromecast advices said so, "if these steps didn't help you can factory reset your device". There was not any info about this problem and that we can not factory reset our deviced.

Very late at Sunday-monday night I thought my chormecast device is broken and that I have to buy new device because our family use Chromecast every day. 

At monday I tried to find out if there is any Chromecast on stores to buy... But no, there is not. Then I saw small headline about this problem... And I realized I'm not the only one who is having problems with Chromecast. After that I have been searching for information about this on my own language (finnish) but there is not much info about it in finnish. Now it's thursday, and yet there is very little information about this.

I really hope that they will tell us very soon how to solve this problem AFTER factory reset... It would have been so great, if this info was here sooner, like immediately on sunday night.

[Revhead2u]

Is something in the device to stop it 10 years on? And  is it a coincidence you stopped developing a new version and now it’s obsolete? I thought It was something I done. Please fix it, how hard can it be? 

[BadFlash]

Just fricking be patient .  The pinned post says they are working on a solution.  They didn’t say the product was dropped .  Learn to read !

[BadFlash]

It can be pretty hard and even impossible sometimes … just be patient , this is a community page and that question already have been asked many times .

[MikaelFamgra]

What is the problem? Either tell us that you (Google) don't have the intention of supporting old devices anymore or just fix it. It´s not like you don´t have the manpower nor knowledge to fix this today if you really wanted to. Right know this issue just damages the Google brand and the companys credibility. 

[johnnyzero2]

It's much more complicated than you think. But If you really must know...

https://www.reddit.com/r/Chromecast/comments/1j8wtxa/heres_why_a_fix_is_taking_so_long/

[BadFlash]

Just relax!  They are working on a fix and this is a community forum, not a google bashing page nor a google support page .

[NeilJames]

Factory reset has been one of the suggested fixes for years, but now it's not?

[BadFlash]

The issue is different this time .  Until they fix the chromecast firmware and/or servers, if you remove it you can’t add it back to your google home without tweaking the date on your phone .  I feel like google  community manager could just provide a bit more information but would be more confusing to computer illiterates entitled people .  Silence is better , just annoying for community members that are actually computer literates 😉

[FabienHoulmont]

Dans quel délai ce correctif sera-t-il disponible ?

Merci

[BadFlash]

On ne sait pas !  Lis le pinned post et tu auras la même information que le reste de la communauté 

[johnnyzero2]

I can confirm that the workarounds posted on Reddit and elsewhere will indeed restore Gen2 casting from Android devices and Chrome browser (sorry, iPhone users). I had mine back up 'n running by Monday morning. Not perfect, but for those who are impatient (and reasonably tech-savvy), it's a viable option until Google issues a proper security certificate fix.

Jag har redan gjort en återställning, innan jag såg erat meddelande. Hur ska jag gå tillväga? 

[Chemawuay]

Buenas tardes!!!....yo tengo Chromecast de 2 generación he restablecido lo de fábrica que debo hacer?....ya me indican 

[Rickyc560515]

This appeared in an Argentine newspaper, but I still haven't figured it out. How is this?

[BadFlash]

Again, I feel like a parrot, YOUR chromecast internal ssl certificate that your applications are using got invalidated because an intermediary CA certificate expired .  We have to wait for a fix .

[babek]

still waiting for update and yes - the first think what i do was "factory reset" and now nothing works - i can also don't install it again with my ios device... very sad...

[BadFlash]

Just wait for the fix and solution 

[Mgr100]

Pedir paciencia está muy bien, pero es el cuarto día sin solución. Cuando lo van a restablecer? Si nos van a dejar sin Chromecast díganlo abiertamente y buscaremos otras soluciones, pero díganlo ya!
