Updating your blackberry OS

 Updating your blackberry OS
So after a great mess, wasting a lot of money I finally figured it how to update my blackberry OS or reinstall one.

So here is the process to help everyone out their struggling with their phones.

1. Install the blackberry desktop software from here.
2. Install the blackberry os for your mobile from here. 
3. Please enable the Show Hidden Files from the Tools options for windows.
4. Now I tried this on Windows XP. Go to C:\Program Files\Common Files\Research In Motion\AppLoader and remove the Vendor.XML file.
5. Next go to C:\Documents and Settings\YOUR_USERNAME\Application Data\Research In Motion\BlackBerry\Loader XML and remove the vendor.xml file again present here.
6. Go to C:\Program Files\Common Files\Research In Motion\AppLoader and click on Loader.exe
7. Follow the steps by clicking next and you should be good to go :)
