How To – Part 10 (Blackberry Tip) How to Install or Upgrade to a New RIM BlackBerry Operating System (OS)

Research In Motion (RIM) is constantly developing and testing new software and applications for your BlackBerry.  Keeping up to date with the newest operating system (OS) software for your smartphone ensures that you have access to all the latest and greatest features and performance tweaks.

First of all, take a deep breath. Everything’s going to be just fine. 😉

What follows is a step-by-step guide on how to upgrade your BlackBerry’s OS.

1) Download New BlackBerry OS Software

2) Download and Install the Latest BlackBerry Desktop Manager Software

I’ll describe the process of removing the XML file in the tutorial, but I’m using a Windows 7 machine. Perhaps the process is different if you’re running Vista or XP?

For the record, here’s how to remove the vendor XML file on a Windows 7 machine:

I.) Open your PC’s Program Files, which are usually found the C drive.

II.) Open your Common Files (within Program Files)

III.) Open the Research In Motion file (within Common Files)

IV.) Open AppLoader (within Research In Motion)

V.) Scroll through the AppLoader folder until you find a file called “Vendor,” that’s in XML format. The file will likely look like a document with a picture of the earth on it and the text next to the image will look like this:

XML document
14 KB

Highlight the file and delete it.

Then run the AppLoader and proceed to your upgrade/update.

Hope that helps…
