After BlackBerry Desktop Manager is installed on your PC, do the following to access Application Loader: 1. On your PC, select Start –> Programs –> BlackBerry –> Desktop Manager. BlackBerry Desktop Manager opens. Connect your BlackBerry to your PC via your USB cable. Doing so connects your BlackBerry to your PC. I also tried downgrading BB Desktop Manager. Also when I tried to 'Add' to the application list, it says 'This application is not compatible with.

Hi guys, First time posting here, not sure which section this should go. I had a bit trouble with my BB 9780.

For some reason, when I tried to upgrade to newer OS version (from leak), AppLoader does not detect for the OS core files installed on my PC. It only detects 3rd apps that I installed from BB AppWorld and/or via OTA I already tried every thing that I can think of but no luck, run out of idea what I should do. Installed BB Desktop Manager 6.1 2.

Installed BB OS 6.0.0.600 from leak for 9780 3. Deleted vendor.xml 4. Run loader.exe, phone plugged in, PIN detected and then next. No OS core files detected, only 3rd apps on the list I already tried with other OS version such.534,.570, it still won't work.

I also tried downgrading BB Desktop Manager. Also when I tried to 'Add' to the application list, it says 'This application is not compatible with your device and cannot be loaded'. I also tried wiping and not wiping the phone. Hi guys, First time posting here, not sure which section this should go. I had a bit trouble with my BB 9780.

I heard that the MaxHybrid messes up your registry making Loader look for an OS in a different path, which is why you can never load a new OS unless you use the uninstaller for that Hybrid to rectify the registry entriesI did use hybrid but it was not an installer, just drag-and-drop from zip files to the OS folder but since sometimes hybrid have a problem itself, now I decided just use the official OS Last edited by valkyr1e; 09-15-11 at 10:59 AM.

Hm interesting. After my Blackberry Desktop Manager got updated (It usually asks you to update when you click on Applications tab on BB Desktop Manager interface), the OS files that are installed in my computer are detected via apploader.exe, it even got detected via Applications tab on BB Desktop Manager. It says 'Local Installation for your Blackberry (model number)' So for you whoever have the same problem as mine might want to try out what I did for BB Desktop Manager. If it is still doesn't work, I suggest uninstall Blackberry Desktop Manager and any OS files that are installed.

Clean registry with CCleaner (free software). Also go to registry editor (regedit) and find (Ctrl-F) any left over Research in Motion keys and delete it manually (Warning: for advanced users, so be careful not too delete other keys otherwise your computer might stuffs up).

And then re-install BB Desktop Manager and your chosen OS files. Those all what I did prior to updating my BB Desktop Manager.
