Beta operating systems are not officially released for good reason: They're often full of bugs and could potentially void your warranty or worse, render your Black Berry unusable.
What follows is our step-by-step guide on how to upgrade your Black Berry's OS, or install a different version, as well as how to prepare beforehand to make the process run as smoothly as possible.
To start a new operating system install, you'll need your Black Berry, an Internet-connected PC, a USB cable and about an hour and half of free time—50 minutes or an hour for the upgrade process and 30 minutes or catch-up time afterwards.
Once logged in, locate the system upgrades section, check to see if there's an OS version that's more recent than the one you're currently running, and if so, download and save it to your PC's desktop.
Save the latest BBOS onto your Windows-powered computer If you decide to download and install an unofficial version of the Black Berry OS, you should beware that you're doing so at your own risk.
Black Berry Desktop Manager version 4.5 If you're not running Desktop Manager v4.5, visit RIM's site and download and install the latest version of the software.
