How to reset your Blackberry.
A reset of a BlackBerry smartphone is a troubleshooting method that will completely power off and restart the BlackBerry smartphone's operating system software and applications. It is a useful first step if a BlackBerry smartphone is experiencing hardware, software, or network problems.
Note: A reset of a BlackBerry smartphone does not delete any settings or data.
There are two options for performing a reset: a hard reset and a soft reset.
A hard reset involves physically removing the battery from the smartphone and then reinserting it. To perform a hard reset, complete the following steps: 1) Remove the battery cover from the back of the BlackBerry smartphone.
2) Remove the battery, and then reinsert it after a few seconds.
3) Replace the battery cover.
A soft reset is a three key combination that resets the BlackBerry smartphone without removing the battery. It is only available on BlackBerry smartphone models with a QWERTY keyboard. SureType® technology and touch screen BlackBerry smartphones, such as the BlackBerry® Pearl™ smartphone, BlackBerry® Pearl™ Flip smartphone, and BlackBerry® Storm™ smartphone cannot be reset in this manner.
To perform a soft reset, complete the following steps: 1) Press and hold down the ALT key on the smartphone.
2) While holding down the ALT key, press and hold down the right-hand CAP key.
3) With both of those buttons still pressed, press the DELETE key. The display on the BlackBerry smartphone will turn off to indicate that the reset has started, and the keys can now be released.
Note: Some BlackBerry smartphones do not display the ALT, CAP, and DELETE keys in the same manner. However, the location of the keys does not change. Please refer to the following graphic for key position:

Additional Information
It is normal behavior for a BlackBerry smartphone to take several minutes to completely start up following a reset.
Some wireless carriers and third-party device manufacturers have processes called master reset, factory reset, or master clear, which erases all user data and settings for non-BlackBerry carrier devices, restoring them to a "factory" state. The wipe handheld command will perform this same function on a BlackBerry smartphone. For further information on the wipe handheld command, see KB14058.
To reset a legacy BlackBerry device ( Research In Motion® (RIM®) 850, 857, 950, 957 devices), insert the end of a paper clip into the small hole on the back of the device.
