Research in Motion’s BlackBerry has undergone a lot of changes over the years, becoming a powerhouse personal digital assistant brand and even branching into the smartphone market. In the spirit of those changes, there comes a time when you may feel the need to give your BlackBerry a clean slate. Maybe it’s to fix a glitch that’s otherwise rendered the device useless. Maybe it’s to roll back to an older OS that you liked better. Maybe it’s just to give it a fresh start, with a fresh installation to give it that “out of the box” performance. Whatever your reason, completely wiping and reinstalling the OS on a BlackBerry is a relatively simple procedure with the right tools.
