Smart TV certificaate issue

Hi all,

We also encountered this issue today. We will check for the new tizen-distributor-certificate provided by the Certificate Manager.

Yet, our worry is: is it expected that all current installations will stop working ? Or, will this certificate change will only impact new (and updated) installation ?

Thanks for your feedback

I tried creating a new certificate but it always return the same error. Did you found how to renew the distribution certificate?

Do you know where does the new tizen-distributor-certificate can be download? The one I have it always shows expire date has 10/27/2022.
And those are very good questions, I would belive this certificate change will impact the new updates, because all the other ones are already in store, but I am not sure.

I just created a new Consumer Display Steps certificate as in the instructions on the link indicating my Samsung account and the DUID of the TV. And it worked for me, as an application developer, I was able to connect to my application via the IDE to SmartTV. Distribution certificate I just specified in the option when creating the certificate.

And now my certificate that I created yesterday is available for exactly one year.

If this doesn’t work for you, I think you should write to Samsung support with a request to provide you with a new certificate instead of the one that ends on 10.27.

As a long-time developer, I now have the exact same problems as you with installing apps and renewing certificates. Is there a workable solution now?

In my case of me, I changed the emulator date to that
Right click on the emulator → Control Panel → Menu → Clock → manual-> Date
I changed it to 10/28/2022 and the issue was solved.
I changed it by 10/27/2022 and the issue still occurs.
I think that the about 10/27 date may be the last date
Anyway, please change the date and then try to test it again

deleted, issue fixed by replacing new distributor cert

Unzip the attached cert and then follow the instructions in the pdf. I also updated Tizen Studio after adding the new cert.

Yes, creating a new certificate fix the issue. But you need to create a Samsung certificate instead of samsung to allow to creata a distributor certificate.

Thank you all for the help

Thank you bob-lang!

Is there a guide I can follow to generate my own distributor certificate?

Felix, I believe that’s something specific to samsung that only they have the ability to create.

Hi @bob-lang , I’ve created a new tizen certificate profile and added the distributor certificate that has been provided by you and followed the same steps but still not able to install the application in the TV. Can you please provide a link where I can find a proper way to generate a tizen certificate profile.

@tharunkoti I basically just followed the pdf that I attached.

Did you create a new Tizen cert or samsung cert, I think it needs to be a samsung cert now for this. I also updated Tizen Studio afterwards, so try that.

You replaced your current dist cert with the one attached?

Yeah I’ve updated the current dist cert with your cert.
I’ve updated the Tizen Studio and tried with this but still facing the same issue. Created a Samsung cert that is also not working.
Can i create a certificate with an existing Author and change the dist cert?

hey, where did you get this cert file and pdf?
i would like to create it on my own

[EDIT] I can create custom one with specific DUIDs but it will be easier if i could have default one


For normal Smart TV’s

The creating Certificate Documentation is on this page

Author Certificates tell the Smart TV Seller Office who you are
The Distributor Certificates tell an individual TV that it is OK to install on that TV and only that devices DUID
You can have many more Device IDs in your distributor list

To run on a Samsung TV you must be the Samsung Tizen Distributor certificate not the certificate.
When you upload to the store Samsung replaces your Distributor Certificate with Samsung. That is probably what you are thinking of as default and there is no way that is available.

B2B and Hospitality and Signage have different requirements and you need to ask for help for those from the Smart TV Seller Office.

Hope this helps,

:grinning: :grinning:Thank you very much, the problem can be solved by using the certificate you provided, but why can’t the certificate I created myself, it is very strange, the distributor certificate created according to the official document has only a 1-year period, (Creating Certificates | Samsung Developers),
Is it convenient to provide the method you created? thank you very much


Can we share the same author and distributor certificate which has been generated using the Samsung certificate to the other developers and use it for the development purposes?

yes, FUBIL008 that was my point.
I was curious about how bob’s distributor certificate will be expiring in 2027 and can be used for any device.
I’m able to create Samsung Tizen certificate but with DUIDs and expiration day 1 year from now.
What is the secret behind bob’s long term certificate :slight_smile:

You can share the Author Certificate (Businesses do that all the time) but the Distributor Certificate is linked to a device (and I think computer) so unless they are testing on your device you would need to add the DUID to the list of devices manually.

The distributor license is purely for running on a device it is replaced when you submit to a store.
