While attempting to backup my Blackberry Pearl 8100 (220.127.116.11 / 18.104.22.168) via Blackberry Desktop Manager ... BlackBerry Pearl forum
Backup Error: Could not establish communications with the device....
While attempting to backup my Blackberry Pearl 8100 (22.214.171.124 / 126.96.36.199) via Blackberry Desktop Manager 188.8.131.52 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.
I'm not sure about it, but have you thought. In upgrading your device DM?
