    use the search button....

    first remove the previous os from your pc, install the os 7.1 and delete the xml file
    back up data and use the apploader

    Assuming you're using a PC.

    Go to Control Panel -> App/Remove Programs (Programs and Features) and find BlackBerry Device Software. Click on it and remove it.

    Next you want to download and install the OS you want on your phone.

    I use BBBoss to shrink the OS, remove features I don't need or want. You can also have it delete the vendor.xml files.

    Once this is done I go to C:\PROGRAM FILES\COMMON FILES\RESEARCH IN MOTION\APP LOADER and select Loader.exe.

    Then just follow the on screen instructions.
