A battery pull (hard reset), restart the operating system on your BlackBerry just like rebooting on your PC. It’s not same as using the power off option. A battery pull (remove the battery from your device) will solve various minor problems, frees up application memory and keep your device running like new. But for those who want to avoid accidentally breaking the battery cover or breaking a nail when remove the battery, there are a few free third applications -that simulate a battery pull- available to download (QuickPull, RestartMe, etc). The other way (similar to simulate a battery pull/hard reset) is perform a “double soft reset”.
How to perform a double soft reset?
- Press and hold the Alt key on the BlackBerry smartphone
- While holding down the Alt key, press and hold the Right Shift key
- With both of those buttons still pressed, press the Backspace/Delete key. The display on the BlackBerry smartphone turns off to indicate that the reset has started, and the keys can now be released. The red indicator light will appear and the screen will go blank
- When the screen is no longer blank, press the keys again (point 1 to 3). You should then see another black screen followed by the red indicator light appear.
- SIM card errors
- Keypad (trackball) stops responding or does not work
- Device display freezes
- Memory leak
- LED notification keeps flashing when there are no new texts-emails, alarms, etc.
- Theme issues
- Java code or module errors appear on screen (e.g. Uncaught exception)
- Bluetooth errors (connecting, pairing, etc.)
- Installing/uninstalling applications & theme
- Social networking applications (Twitter/Facebook) indicate there is no connection available
- Etc.
