Hard reset your Motorola Droid Bionic if you wish to set the device back to factory default settings. A hard reset will wipe all data from the memory of the device and return settings to where they were out of the box. This is useful if you are selling your phone or returning it to the store. It can also be useful for recovering a malfunctioning device.
Note: These steps will delete all data from the memory of your phone. Be sure to backup your data first before performing any of these steps if you’ll need it in the future.
Using the OS menus
If you can start the Droid Bionic normally and access the menus, this method is preferred.
1. Open the Settings app.
2. Select Privacy.
3. Tap Factory data reset.
4. If you wish to erase the photos, music and other personal data on the SD card, you may want to check the Erase SD card option. To keep the SD card data and just clear the memory and settings on the phone, leave the selection unchecked. Tap Reset phone.
5. Select Erase everything.
6. The phone will then shut down and start the factory hard reset process. When the device restarts, all data will be set back to factory default settings.
