App cannot launch on TV NU7452 : Error "closed", sdb install "closed" - "tizen install -n" working with strange behaviour

Hi All,

 

I have a strange behaviour on my NU7452 TV,

I cannot launch the application on the TV from Studio or through sdb,

TV is in dev mode to IP of the Tizen studio PC.

permit to install - working fine.

tizen install -working fine  - with some side effects : one icon present - allways just for the latest installed app.

tizen run - working fine - even for the app which has no icon in the apps lists

tizen uninstall - not working - "failed to uninstall",

sdb uninstall - working fine

sdb install - not working. error message "closed"

tried several things and studio version, 1.3, 2.5, 3.0, 3.1 - with extension 2.3, 3.0, 4.0 - allways the same issue.

according to my info the TV  should support extension 4.0.

 

with tizen install -n I can install the apps, but I have strange behaviour. just one icon is visible for the app in the apps lists.

when I want to install 2 version of the app for testing purposes( with changed application ID, changed icon etc...) - (on other TV it is working fine..) , the icon is allways launching the latest installed app(no icon present for the earlier installed app), although tizen run $APP_ID is starting the earlier installed app without issue.

 

Could you please help me with this ?

why the icon is missing, and how to solve the "closed" message?

Thanks.
