For the Android phones you can do factory reset from the Android System Recovery Menu. This will erase all your data.
Switch off the phone. To go into the Recovery menu, press and hold the Power On button and some other key (Volume Up, Volume Down, Home ). The combination is different for the different models.
When you are in the Android system recovery menu, use The Volume Up/Down keys for navigation and the Power button for confirmation.
Choose "wipe data / factory reset"
