You can do a factory reset from the system recovery. This will delete everthing off the phone, even the password.
To do this:
- Pull the battery and power back while holding the X button. Once you see an Android with the triangle & exclamation point, press the Search button on the keyboard.
- The Motorola Droid 2 Global is now in the factory recovery image, use the arrow keys on the keyboard to move around and the Camera button or OK on the keyboard to select.
- Select the option to Wipe data/factory reset.
Once the wipe is finished, select Reboot system now.
