I had 5.0 loaded on my 8900. I then loaded the new bbm 5.0 and lost the icon, I got frustrated and went back to the newest 4.?? from tmo and now cant get the 5.0 to load back. When I try, I download 5.0 again and hook up th bb but the dm does not find it and automatically do it. How do I get 5.0 back on it?
Once it is installed to your PC, go to C:/Program Files/Common Files/Research In Motion/Apploader, in this folder you will see a file name "vendor.xml", rt click on this file and delete. This will allow you to install the OS. In the same folder double click the Loader.exe icon (looks like a phone) this will launch the loader program.
