Re: 'Syncing and starting application has encountered problem

Are you able to connect the device through the setup wizard? Ensure the IP youre connecting to is the one shown in the  simulator :


Do you get any error message?

As I told you, the QML Preview is not working with Java 7, Im having the same problem

Re: 'Syncing and starting application has encountered problem

This is a known issue in some releases of BlackBerry OS 10.1. See the link below for details and a workaround.


Application Deployment may hang or fail after OTA Update to 10.1.

Re: 'Syncing and starting application has encountered problem

Dear All,

but still facing the same problem. you can find more details here
Here I am facing a small probem regarding BB 10 native cascades .bar Installation and debug. I am using Blackberry 10 Dev Alpha B .
Please find the Blackberry Z10 Details here.
Model : Blackberry Z10
Model Number : STL 100-1
OS version:
my machine Configurations :
Operating System  : windows -7 
I am developing one BB 10 native application and I successfully Install the bar file once from my QNX IDE as Blackberry Tools->Install. Later I unstall the app.
now when I try to Install in the same way, I am getting the bellow Error. 
After getting the Install Error, I am unable to make even  device debug from my QNX IDE.
and getting the same Install Error.. I also tried Hello world to install/ debug. but getting the same error which means that this error is not related to app coding.
Is there any idea why this problem is getting while Installing the bar file and making the device debug. 
I would be very happy If I get a solution from your side and looking forward for your reply.
syncing and starting the application has encountered a problem
