To remove an IT policy from a BlackBerry smartphone, use one of the following methods:
Method 1
Before removing the account from the BlackBerry Enterprise Server, create a blank IT policy on the BlackBerry Enterprise Server, and assign it to the BlackBerry smartphone user account.
Method 2
You can remove the IT policy using the loader.exe application included with BlackBerry Desktop Manager 4.7 to 6.0 on a Windows based computer.
Important: This method can only be used on BlackBerry smartphones that are running BlackBerry Device Software 4.3 to 6.0.
Note: When using BlackBerry Desktop Manager 4.6 or earlier, the loader.exe application can be updated by going to www.blackberry.com/update and installing the software when prompted.
Warning: This procedure deletes all data on the BlackBerry smartphone. Back up the data before performing this procedure.
1. Connect the smartphone to the computer.
2. From the Start menu, click Programs > Accessories > Command Prompt.
Note: When a computer running Windows Vista or Windows 7 is used, the user might need to right-click the Command Prompt application and choose Run as administrator.
3. Find the Apploader folder by typing cd C:\Program Files\Common Files\Research In Motion\Apploader and then pressing ENTER.
Note: For computers using a 64-bit version of Windows, navigate to C:\Program Files (x86)\Common Files\Research In Motion\Apploader
4. Type loader.exe /resettofactory
5. Type the BlackBerry smartphone password if prompted.
