Step 1 : Download BlackBerry Desktop Manager latest version from the official BlackBerry Site.

Step 2 : Download the OS that you want to install on your device. You can find and download the latest official and leaked OS from 2-Soft of course. Is not necessary to download your carrier’s specific OS, any leaked version is good as long is compatible with your device.
Step 3 : Install the downloaded file on your PC.
Step 4 : Delete file vendor.xml from the path C:\Program Files\Common Files\Research In Motion\AppLoader (the path depends on where you have installed your BlackBerry Desktop Manager).
Step 5 : Use the USB cable and connect your BlackBerry device to your computer.
VERY IMPORTANT: The mass storage mode must be turned off during the OS update.
Step 6 : Run Desktop Manager- Your new OS should be detected automatically.
Step 7 : Fallow the steps that will appear on your screen.
Step 8 : Your BlackBerry will be update after the reboot. Be patient because the reboot could last for over 30 minutes.
IMPORTANT: Don’t forget to back up your data before beginning the update. If you don’t do this you LOSE all of your data!
