    Good for you, always a good idea to have a roll back plan in place... just in case.

    Every OS I have seen has a Vendor.xml file in C:\Program Files\Common Files\Research In Motion\AppLoader

    There's no guarantee that ths will work for you but here's how I downgraded my 8310.

    - Delete the newer OS (I also deleted the Apploader folder)
    - Install the older OS. In your case 4.3.0.124 from here.
    - Delete Vendor.xml from the folder above.
    - Run DM
    - Connect you BB to the PC
    - Launch App Loader and it should ask if you want to install the older OS.

    If that does not work then I am out of ideas (apart from using JL_Cmder to brick your phone and starting over) BUT, there are many, other here who can certainly help more.
