I have a 7290 bberry that after power on - will just blnk the red light very, very fast - like 1-2 blinks per second - & the main screen is just showing me the rotating hourglass..

The desktop manager will only detect the unit upon initial power on & I can't get the app loader to re-initialize this unit.

Any idea as to what is happening.

I had this unit for 3-4 months without any problems

Thanks

Did you take the battery out and replace it?
