Turn off Content Protection before manually erasing all data and applications from the BlackBerry smartphone, in order to avoid triggering the scrubbing process:

1). On the Home screen of the BlackBerry smartphone, go to Options > Security Options.
2). Under General Settings, go to Content Protection.
3). If Content Protection shows as "enabled," click the trackwheel of the BlackBerry smartphone and select Change Option to turn off, or "disable," Content Protection.
4). Click the trackwheel again to save and close.
Once scrubbing has been triggered, there is no way of stopping it. The process must be fully completed before the BlackBerry smartphone may be used. Removing and reinserting the battery of the BlackBerry smartphone will only start the scrubbing process again from the beginning.
The duration of the scrubbing process depends on factors such as the actual processor speed of the BlackBerry smartphone, the amount of memory that it has, and the actual memory speed.
