Error 507 means the device does not detect any operating system installed on the device.


See the link below for the download, and follow these simple installation instructions.

First locate your carrier and the OS file you wish to use.

1. Download the OS file to the PC then install it to the PC by running (double clicking) the file you downloaded.
2. Go to c:\program files\common files\research in motion\apploader and delete the file named "vendor.xml."
3. Plug in BB and double click on "Loader.exe." It's located in the same place as the above vendor.xml file.

I've exactly the same problem. It says:

error 507

Reload Software


I've dowloaded the last OS version. Deleted the vendor.xml, and tryed to connect it with the loader.exe from folder APPloader.


zero. The application doesn't recognize any port 


Pull -off the battery from the phone, connected only with the USB cord to the PC, but the message “USB-PIN: UNKNOWN” never comes...


Any Ideas?


Help will be highly appreciated.
