Always backup your settings using Desktop Manager before performing any OS upgrade.

1. Remove all Blackberry OS version from your PC... Add/Remove programs, then be sure all Blackberry OS version are deleted.
2. Download and install the OS from the Sticky thread at the top of the Forum.
3. Delete the Vendor.xml file in the "C:\Program Files\Common Files\Research In Motion\AppLoader" folder
4. Start the upgrade by starting the Loader.exe file, located in the same folder as the Vendor.xml file you deleted above.
