Hi and Welcome to the Community!

What you describe is a bit brief, so let's start with the full and complete process that is required:

1) Make sure you have a current and complete backup of your BB...you can find complete instructions via the link in my auto-sig below.

2) Uninstall, from your PC, any BB OS packages

3) Make sure you have the BB Desktop Software already installed

4) Download and install, to your PC, the BB OS package you desire:

  • http://us.blackberry.com/support/downloads/download_sites.jsp
  • It is sorted first by carrier -- so if all you want are the OS levels your carrier supports, your search will be quick. However, some carriers are much slower than others to release updates. To truly seek out the most up-to-date OS package for your BB, you must dig through and find all carriers that support your specific model BB, and then compare the OS levels that they support.

5) Delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:

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

6a) For changing your installed BB OS level (upgrade or downgrade), you can launch the Desktop Software and connect your BB...the software should offer you the OS package you installed to your PC.

6b) Or, for reloading your currently installed BB OS level as well as for changing it, bypass the Desktop Software and use LOADER.EXE directly, by proceeding to step 2 in this process:

If, during the processes of 6a or 6b, your BB presents a "507" error, simply unplug the USB cord from the BB and re-insert it...don't do anything else...this should allow the install to continue.


 

Give that a try and see if you can resolve the problem. If not, then the typical reasons for what you see are:

  • There is no BB OS Package installed to the PC
  • There is a BBOS package installed to the PC, but it's for the wrong BB model number
  • There is a BBOS package installed to the PC, but its' for the exact same version that is already running on the device, and you used 6a from the above
  • Both copies of Vendor.XML have not been deleted

It is very easy to make an error...and if ANY error is made, then the process is invalidated, and the automatic process takes over, ignoring what you are attempting to manually push to your device.

 

Good luck and let us know!
