Re: how to install os

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

http://na.blackberry.com/eng/support/downloads/download_sites.jsp

2. Download the OS file from step 1 to the PC then install it to the PC by running (double clicking) the file you downloaded.

3. Go to c:\program files\common files\research in motion\apploader and delete the file named "vendor.xml." Also check the following locations for vendor.xml files and delete any instances of the file:

On Windows Vista/7 navigate to C:\Users\YOUR_USER\AppData\Roaming\Research In Motion\BlackBerry\Loader XML (Where "YOUR_USER" is your username)

On Windows XP navigate to C:\Documents and Settings\YOUR_USER\Application Data\Research In Motion\BlackBerry\Loader XML (Where "YOUR_USER" is your username)

4. Plug in BlackBerry and double click on "Loader.exe." It's located in c:\program files\common files\research in motion\apploader
