If you’re experiencing problems with your BlackBerry Torch 9800 smartphone, you may want to try to hard reset the device.
The BlackBerry Torch manual describes a hard reset as removing the battery for about 10 seconds, then placing the battery back into the device. This does clear up many temporary issues with the device, but there are other resets you can perform.
Press ALT + RIGHT SHIFT(CAP) + DELETE.
Press ALT + RIGHT SHIFT(CAP) + DELETE . The screen will go blank for a few seconds. When the screen comes back on, immediately press ALT + RIGHT SHIFT(CAP) + DELETE again.
If none of these help your issues, you may want to wipe all data from the device and start anew with factory default settings.
