Receiving "unknown error" when attempting to backup device. I cleared the entire browser cache but still receive the error.
What's my next step?
Go to Browser>Menu (BlackBerry Button)> Options>Cache Operations, and clear all of the tabs.
If you continue to receive an error, open the Desktop Manager in your computer.
In Desktop Manager, under backup/restore, go to Advanced.
You should see a list of databases in the right box, and an empty box on the left. If you select an item on the right, and then hit the left arrow button in between the boxes, it will back it up, and it will show up on the left.
To avoid having to do that 1 by 1, is highlight about 10 at a time and transfer them over. Eventually you will find the error, but it will be narrowed down to 10 databases, then go through individually with those 10 and find the one with the error. Then hit clear database right underneath the right box.
Now you can go back out to the backup/restore page, and it should work.
