How to Hard Reset a Windows Mobile 6
Technical issues may cause your Windows Mobile 6 device to require a hard reset, which clears out all data from the phone and reverts all programming back to the original manufacturer's default settings. A hard reset cannot be reversed; once it is done all your personal information will be cleared from the mobile phone. Windows Mobile 6 phones either have built in software programs that you can access to clear the storage, or you can click the reset button on the device.
Press both the soft keys used to select and access software.
Simultaneously press and hold the "Reset" button with a small pointed object like a toothpick or gem clip for five or more seconds. The "Reset" button is located on the back of the phone.
Wait for the phone to power off and turn it back on, if it does not do so automatically.
Clear Storage Program
Access the menu of the Windows Mobile 6 and navigate to "Settings." Select the "System" tab.
Click on the option to clear storage.
Type in the password "1234." When prompted to accept the warning that your data will be erased, click "Yes."
