i downloaded the multi-language 4.5.0.57 update for my 8120 but when i start the device manager it doesnt update. I have the latest 4.5 version of the desktop manager. My friend upgraded his 8100 on my computer with the 8100 4.5 installer and it worked. I then uninstalled that and installed 8120 4.5 and it doesnt work. Anyone with solutions?
1. Download and install the latest version of Desktop Manager
2. Download OS and install it to the PC.
3. Delete the vendor.xml file located in c:\program files\common files\research in motion\apploader (this step is necessary any time an OS is installed from a different carrier than what is branded on the BB.)
4. Plug in BB and open Desktop Manager. You should be prompted to upgrade.
