I was installing a software upgrade on a BB7780 when it locked up tight with a "Device Error: 400" message. Cannot reset using keystrokes or paper clip. Tried removing battery too but no go. Any suggestions?
 
I received an error 507 on the 6750 model when I was trying to use the Application Loader. The results were identical to what you report here.

It turned out that the Belkin Serial-to-USB adapter I was using was the culprit.

The connectivity was problematic in the sense that something was corrupting the data transfer in some fashion.

Out of the 4 I "killed" this way (2 on purpose to isolate the problem), all had to be returned as they could not be reset or made to function again.
