Visual studio 2019 with Tizen - certificate error 12 / 14 when deploy to samsung galaxy watch

Question

Hi, this is second day that I can't just deploy my wearable app from VS2019 through the tizen device manager to my samsung galaxy watch. I have been developing this app for few months without any problem, every day 10 times deploy with no problem.

I go through all of google site / forums, where talking about this, but without any results.

VS2019 + Tizen SDK (certificate manager and device manager). Samsug Galaxy Watch - dev mode, wifi on, RSA key accepted. Certificate with Samsung acc signed.

I really try everything. Restart / Reset my watches, Restart PC, delete all certificates and create new one, nothing helped. I am succesfully connected to my watch via Tizen Device manager I can build and send my app to debug or release to my watch.. Loading dialog appear for 0-25% in 5 seconds, after it dissapear and it look like I am in debug mode, my app is open but not my new version. When I stopped debug, in log console:

signature error in certificate profile (Error: -12)

20 times I try delete, create new certificate, set default certificate, restart / reset whatches.. Even completly uinstal VS, clean all files, clean instal of VS2019 with tizen SDK, new connect to watch, new certificate.. NOTHINK :-(

What is happening? :(

Hi @Roman Rusz ,

Welcome to Microsoft Q&A forum.

From the error message “signature error in certificate profile (Error: -12)”, it seems the issue is related to the certificate profile and signature.

Did you change something(signature or certificate profile related) or perform some different operations before this error appeared? I’m not very familiar with Tizen, are there any conflicts between certain processes?

Since you mentioned that you have tried everything include reinstalling Visual Studio, I may also suggest you post this issue in Tizen forum for some Tizen or certificate related suggestions.

Best Regards,
Tianyu
