1 - Backup your BB
2. If you haven't already, download and install the latest "released" version of your device from DMFM. (this will create folders discussed later).
3 - Open up Finder and go to
Library>Application Support>BlackberryDesktop>Device Applications
There will be two folders, go to the folder that has a combination of #'s and letters. The other folder is your device apps.
4 - Open up the Java/Hybrid file folder in another finder window.
5 - Copy all the COD files from the Java/Hybrid folder and paste them into the folder that is labeled with #'s and letters that you opened up in the first Finder window. Make sure you "Replace All" when you paste.
6 - Open up Mac DM and click on "Applications" in the top right hand corner.
7 - Another window will open up, click on "Check for Updates"
8 - Window will then minimize. Click on "Show Other Versions"
9 - Another window will open up which might be blank or show another OS. Click "Cancel"
10 - You will then see the window showing current OS. Click on "Start Update".
11 - This will start uploading the OS files that you pasted in the folder with #'s and letters as well as your Device apps.
12 - Grab a beer as this part takes 15-25 minutes to complete update.
BTW, We think the folder Device Applications is created when you install an OS on your device. So one approach would be to wipe your device. Connect to DM and install OS, and then do the hybrid updates as above.
