    Make sure you dont have the 4.5 OS installed on your pc. Download and install 4.2 to your pc. Delete the vendor.xml file if the 4.2 OS isnt from Tmobile. Its located in C:/program files/common files/research in motion/apploader. Make sure you backup whatever it is you want to backup. Keep in mind that some apps/themes you may have now might not work on 4.2
    After you have all that taken care of I would wipe the device with jl_cmdr get it here http://forums.crackberry.com/f2/how-...l_cmder-53502/
    No go back to C:/program files/common files/research in motion/apploader and click on the loader.exe it looks like a phone. That will start the downgrade.
