Hi jcambusa

 

Welcome to the Community

 

 

There are multiple thread available regarding OS upgrade .You can also Try this :

 

 

 1.Locate your Carrier and Download the OS you desire from here and Install it in your PC or Laptop Carriers

  •    (make sure you are downloading for the same model as you have )

2. Download and install the latest BlackBerry desktop software from here BlackBerry desktop software

  •     Then using desktop software perform your full backup of your device.   

3.Search your C: drive for Vendor.xml and delete them, there may be one or two vendor.xml ( On your Pc change your folders option to show hidden files/folders ) :

  •     C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
  •     C:\Users\Windows UserName\AppData\Roaming\Research In Motion\BlackBerry\Loader XML

5. Go to C:\Program Files\Common Files\Research In Motion\AppLoader. (For 64-bit Vista or Windows 7, the path       will be C: > Program Files x86 > Common Files > Research In Motion > AppLoader) double click Loader.exe

 

      Upgrade will continue then After Installation of New OS restore your backup from BlackBerry desktop

Software.

 

Try it and let us know.
