1. First you will need to go to the Control Panel> Uninstall> Programs and then uninstall all program that does not read "BlackBerry device software. And here I will suggest you to make sure that there is desktop management software.
2. And before opening the Desktop Manager, download the OS 5.0.
3. And after the downloading is finished at that time go to C: / Program Files / Common Files / Research in Motion / Application Loader and delete the file Vedor.

I have wiped my device and displays a blank screen with 507 errors. I'm trying to connect my BLACKBERRY with DM, but not connected. What I can do? For that I deleted the files from vendors and DM before loading. by the way the model of my device is a bold 9000. White screen with 507 errors.

Here I would like to say that Did you use to clean the device. If so, then you're in the right direction. Have you tried with the following :

• BlackBerry OS 5.0 uninstall the team, going into Add / Remove Programs
• re-download the OS 4.6 for your company, if you can find and install. Or try to Downloads OS directly use the application loader and then go to C:> Program Files> Common Files Research> In Motion> apploader> apploader.exe

I have used this method to downgrade from 6.0 to 5.0. Luis mentioned this in the first place. The important thing is to get rid of the latest operating system first
