Hi Sandy,

As a last resort, the phone can be factory reset.

1. Press and hold the power and volume up button.

2. When boot window appears use the volume up and down button to navigate through the menu.

3. Hover over "wipe data/factory reset" and press the home button once.

4. Confirm the reset when prompted.

这个答案有帮助吗?
