I installed the 4.5.0.81 on blackberry a couple of weeks ago and it has been pretty buggy for me. How can I go back to my old OS (I think it was like 4.3 or something.) Thanks for any help you can give me.
Uninstall the newer OS, install the older one, and DM should alert you that's there's an OS update. Thankfully, DM considers a different OS to be an update. Doesn't matter if it's an older version.
