If you're on Windows, as opposed to a Mac, DL the Passport autoloader Passport_10.3.02.2789_SQW100-1-2-3-4.7z, and use that after unzipping it. Run the program, it'll bring up a CMD screen looking for the BB Boot Rom, connect the Passport via USB, holding the top button long enough to turn it off, first, if possible. I've never had it fail, so long as BB Link is also installed on the computer (but not running). There is also a thread here about what to do if you get the "blue light" on the BB and how to fix it--BlackBerry has a Windows based program for that. Most likely, though, the autoloader will work. If you do get the autoloader to install--and don't restore /anything/, of course--and you still have the auto reboot problem, then the only thing to do is to send the device back.
