The following are codes that you can use on a BlackBerry.

Hard reset
The first step in troubleshooting a network, software or hardware error is often to perform a hard reset. With Java® based devices, this is accomplished by removing the battery, while the BlackBerry device is powered on. Hold the battery out for about 30 seconds, and replace. The BlackBerry device will reboot.
Note: A hard reset on a C++ based device is accomplished by pressing the Reset button.
Note: To perform a hard reset on a RIM models 850, 857, 950, or 957 device, insert the end of a paperclip inside the small hole on the back of the handheld.
