    Thumbs down Backup Error: Could not establish communications with the device....

    Advertisement



    While attempting to backup my Blackberry Pearl 8100 (4.2.1.107 / 2.3.0.83) via Blackberry Desktop Manager 4.3.0.15 I got this message:

    "Could not establish communications with the device. A required application is missing from the device."

    I was having problems using the WAP Browser and getting e-mail on my Blackberry, but not the OperaMini browser. A while back a T-Mobile Blackberry tech said that doing a "battery pull" would refresh the device and the Service Books - after I did that the WAP browser worked and I started getting all my e-mail. Today I wanted to do a backup and got the above message.



    What could have happened here? I have not called T-Moble because thier tech desk is closed.

    Thanks in advance.

    Paul.
