    back up your information, wipe the phone and load the 4.2. you could also download the 4.2 OS to the desk top and delete the vendor.xml file and delete the 4.5 OS and see if the DM prompts you to downgrade.
    Color---it's nothing but a hue of the rainbow...why do people place such importance in it?

    Not necessary to wipe.

    Delete the 4.5 OS from your desktop, install the 4.2 OS. When you launch DM / App Loader and connect the phone it should prompt you to install the 4.2. Check Red's FAQs in my blog (click on the link to the left) for downgrade instructions.

    You need to go into your control panel on your computer and uninstall the 4.5 operating system from your desktop. Then you need to download and install the 4.2 OS you want on your desktop. If it is not from your carrier you will need to delete the vendor.xml file.

    gary is right, a wipe using jl_cmder is NOT necessary.
    i have NEVER had to wipe the bb to do a downgrade.

    all you have to do is uninstall the 4.5, reinstall the 4.2, delete the vendor.xml file and off you go application loader will prompt you and ask if you want to downgrade. you *shouldn't* lose anything.
