A full reset is sometimes referred to as a hard reset. Perform a full reset when you want to clear all settings, programs and data from RAM.
Caution if you perform a full reset, your BlackBerry 8800, 8820 or 8830 returns to its default settings and looses all information that is not recorded in ROM.
Before you delete your BlackBerry® device data or media card files, consider backing up these items so that you have a copy on your computer.

If you reset your device, the process restarts after the device restarts.
