How to Upgrade Blackberry OS

1. Locate and identify your current BlackBerry OS version
2. Find it here: Options > About
3. You need to identify your current OS version to know whether you are upgrading or downgrading. For the purpose of this guide you are upgrading, but the process is the same for downgrading your OS.
4. Download and install the BlackBerry OS you want to upgrade to.
5. You can get the latest BlackBerry OS for your BlackBerry at your service provider’s website. An example would be tmobile.com/bbupgrade for T-Mobile USA. Your service provider will have the latest official OS for your BlackBerry.
6. You can also check for and upgrade to the latest OS for your BlackBerry at the RIM BlackBerry Site here http://us.blackberry.com/support/downloads/download_sites.jsp
7. In the event that you decide you want to install an unofficial BlackBerry OS or an OS from another service provider you must follow these steps:

• Download and install the unofficial OS or other service provider’s OS.
• On your PC go to Program Files > Common Files > Research In Motion > AppLoader
• Delete the vendor.xml file.

8. To install/upgrade the BlackBerry OS you installed on your PC you can do one of two things.

• If the OS you installed on your PC is your service provider’s, simply run BlackBerry Desktop Manager and select Application Loader.

• If the OS you installed on your PC is unofficial or from another service provider you must use the Loader program, which you can find in the same location the vendor.xml file was: On your PC go to Program Files > Common Files > Research In Motion > AppLoader

Using the Loader program (official OS or not) > it is basically the Application Loader without theBlackBerry Desktop Manager running in the background.

This guide using the Loader program.

9. Run the Loader program.
10. Go through the prompts and make sure all the settings are the way you want them to be, including which applications will be included in the update, which languages you want, etc
11. You will come to a screen that asks you if you want to automatically backup device application data (including messages) and then restore the backup after the process is complete. It is highly recommended that you do this even though we made an initial backup in the beginning
12. In the next screen you will come to a summary page of what will happen in the update process. Click finish.
13. Your BlackBerry OS will now be upgraded, along with the other settings you specified.
14. After the loading operation is complete your BlackBerry might take a few minutes to load up completely
