THERE ARE TWO WAY TO DO THIS
back up all file on your unit before doing this.
1. GO TO SETTINGS>privacy>factory data reset
2. IF YOUR UNIT LOCKS UP OR YOU CAN'T ACCESS THE MAIN SCREEN
turn your unit off>hold the + volume tap and hit the power button the unit will look like its going to boot up but you will get an android screen with yellow letters> use the + volume button to scroll to factory data reset -- volume button to enter> follow the same steps to scroll to reboot unit.......Mark A.
