I was trying to test my app on a new iPad to see if Retina support is working.

Like anyother devices I used for development, I attached the device and pressed "Use For Development" is XCode Organizer.

The process started but a few seconds later the progress bar went away and I received this error message : " An Unknown Error Occurred "

I registered its UDID in devices section manually and the provisioning profile is successfully installed on the device but there still is a yellow dot in front of iPad's name in organizer and the device is not appearing in the iOS Devices list ( so that I cannot run my app on it ).

I tried anything came to my mind but nothing worked out :(

enter image description here

Any ideas ?

Additional Info :

  • XCode version : 4.4.1
  • iOS SDK version : 5.1
  • Minimum Deployment Target : 5.0
  • Device iOS Version : 5.1.1 (9B206)
  • Device type : 3rd Gen New iPad ( Wifi + 4G )

Try disconnecting / reconnecting the iPad, quit and restart XCode, ... Sometimes it just won't work and restarting everything solves it !
