Delete all data from my device
Before you delete the data from your BlackBerry® device, consider backing up your data so that you have a copy on your computer before you delete it
from your device.
Research In Motion recommends that you regularly create and save a backup file on your computer, especially before you update any software. Maintaining an up-to-date backup file on your computer might allow you to recover device data if your device is lost, stolen, or corrupted by an unforeseen issue.
CAUTION:
If you have turned on encryption, the process for deleting all device data can take up to an hour to complete. You cannot
stop the process after you start it. If you reset your device, the process continues after the device restarts.
