i have the same problem on a 8700g, but i am unable to load a new OS since the startup proces of the blackberry doenst seem to finish (running for 2 hours now). Even after re-instering the battery the hourglass is all i see.
The BlackBErry device manager doesnt see the device so i cannot re-install the OS. Also tried connecting the BlackBerry without a battery but doenst work. I cannot believe i destroyed it within 2 hours after arrival, there has to be a way.
It happened after the battery drained during a security wipe operation.
