1. Download and install DM 4.3.
2. Hook blackberry up and run a backup on phone.
3. Download and Install JL_cmder
4. Wipe BB using JL_cmder
5. Download and Install 4.5 OS update
6. Delete vendor.xml file
7. Pull battery out after phone is wiped. Hook up to computer and start DM.
8. Click on application loader
9. Because the battery is out, the computer may act like it cannot find the phone. Just click next to continue
10. DM should show the new 4.5 os update in the application list. Check the programs you want to install and click next/install
11. As soon as the DM begins the OS install (I believe it erases applications first) pop the battery back in. If you don't do it in time, then the install will fail.
12. Let DM install the OS update
13. After DM says it is done with the update, unplug the phone and wait patiently. The phone initialization will take FOREVER (mine took almost 15 mins).
14. After BB comes back to life, hook BB up to computer again and run Restore.
15. Enjoy!
