Berry nuked? It should have a white screen that has the number 507 somewhere. Yes? Now to reinstall the OS.
open BBDM. Instead, uninstall all operating systems for the lobotomized berry. Find a current official OS and install it after you banish all other OSs from your system.
Now that the new OS is installed, find the vendor.xml file on your computer and delete it. On a vista machine it will be in c:\program files\common files\research in motion\apploader.
While in this folder double click on Loader.exe. This will install the new OS. Follow the directions and your berry will be back up in no time. Ok, maybe an hour. Probably less.
Do not restore your berry. This will reinstall the IT policy we just nuked. Instead, use the sync option to get back your address book, tasks, memos, and calender.
