    Plug your phone into a computer via USB cable, start up. Blackberry Link and select restore. It. Will put your phone back to factory reset.

    Backup your phone and know that there might be calendar settings inconsistancy if you choose to back up from a higher version and then downgrade... Other than that you can basicly choose any leak you want or reset to carrier as described above.
